1.0) What is ColecoVision?

Coleco (a contraction of COnneticut LEather COmpany) was the first
company to introduce a "dedicated chip" home video game system, with
the Telstar Arcade in 1976.  (The Magnavox Odyssey, based on Analog
technology, was the first home video game system overall, debuting
in 1973.)  Trying to build upon the enormous initial success of the
unit, Coleco decided to bring out nine different Telstar models.  But
within a year, 75 other manufacturers had introduced similar units, 
and combined with with production snags, a shortage of chips, and a 
push towards hand held games, Coleco skirted with disaster.  While
Coleco sold over $20 million of hand held games, it had to dump over
a million Telstar units, and the company lost $22.3 million in 1978.
With the introduction of units with games stored on interchangeable 
cartridges, Fairchild and then Atari had eliminated any remaining
market for the simple pong games.

On June 1, 1982, Coleco re-entered the fray with the announcement of
its "third generation" video game system, ColecoVision.  Touting
"arcade quality", ColecoVision took aim at the seemingly unassailable
Atari 2600.  Coleco wanted "Donkey Kong", a very hot arcade hit, to be
their pack-in.  In December '81, they went to Japan to make a deal with
Nintendo for the rights to Donkey Kong.  The Coleco executive wanted to
return to the US to show his lawyers the contract before signing, but was
told to sign now, or risk losing Donkey Kong to Atari or Mattel, who were
currently going though channels to get the rights themselves.  Under the
pressure, the Coleco executive signed.

In April '82 Coleco and Nintendo were threatened with lawsuits from Universal
Studios who claimed Donkey Kong was an infringement on their King Kong.
Coleco had invested a fortune in the ColecoVision version of Donkey Kong
that was only 4 months from its premiere release.  Thinking that they didn't
stand a chance in court, Coleco decided to settle, agreeing to pay Universal
3% of all Donkey Kong sales.  Nintendo decided to fight it, and some time
later actually won.  Coleco then filed suit and got some of their lost
royalties back.

The bulk of Coleco's library, however, was comprised of overlooked coin-op
games such as Venture and Lady Bug.  With a library of twelve games, and
a catalog showing ten more on the way (many of which were never released),
the first one million ColecoVisions sold in record time.  In 1983 it topped
sales charts, beating out Atari and Mattel, with much of its success being
contributed to its pack-in, Donkey Kong.  The ColecoVision soon had more
cartridges than any system except the Atari 2600, and with the 2600
converter still today has more playable games than any other system.

The ColecoVision introduced two new concepts to the home videogame
industry - the ability to expand the hardware system, and the ability
to play other video game system games.

The Atari 2600 expansion kit caused a flurry of lawsuits between Atari
and Coleco.  After the dust cleared, the courts had decided that it was
acceptable for Coleco to sell the units.  As a result of this Coleco
was also able to make and sell the Gemini game system which was an exact
clone of an Atari 2600 with combined joystick/paddle controllers.

Coleco was also the first home videogame maker to devote the majority of
their product line to arcade conversions, using the superior graphics
of the ColecoVision to produce nearly arcade-quality games, albeit often
missing a screen or level.

Coleco truly shocked the industry by doing so well.  In a year, the stock
rose in value from 6 7/8 a share to 36 3/4.  The following items were 
taken from Fortune or March 7, 1983:

"Six months ago, hardly anyone expected Coleco to ride so high.  [Company 
 President Arnold] Greenberg was known in the industry as a  self-promoter 
 overly sanguine about Coleco's prospects.  Says one security analyst: 
 "He was always gilding the lily.  Wall Street developed a basic distrust 
 of the company."  So did the Securities and Exchange Commission.  In 1980 
 it charged Coleco with misstating financial results to mask troubles."
 
"But almost overnight Coleco's image has changed.  ColecoVision, the 
 video game player introduced last August, is one of the most popular 
 consumer products around.  The trade, paying homage to its technological 
 advancement, has dubbed it "the third wave" - wave one being the Atari 
 VCS, wave two being Mattel's Intellivision - and the most discerning 
 critics, kids, love it.  The 550,000 game players Coleco made last year 
 flew off the shelves by Christmas-time.  Coleco's sales nearly tripled 
 from $178 million in 1981 to $510 million last year, and the net income 
 shot up 420% to $40 million."

"Coleco's charge into the market last summer was well timed.  Atari and
 Mattel were engaged in a multimillion-dollar mud-slinging battle on
 television.  George Plimpton in Mattel commercials lampooned the graphics 
 on Atari's VCS game player, while Atari blasted Intellivision's dearth 
 of hit games.  Then Coleco suddenly arrived on the scene with the best 
 of both: good graphics and good games.  With a greater amount of memory 
 allocated to screen graphics, ColecoVision provided a much better 
 picture than Atari.  Although ColecoVision at $175 was $75 more 
 expensive than Atari's VCS, discerning video players were willing to pay 
 a higher price for more lifelike graphics.  ColecoVision's pictures were 
 also better than those of Intellivision, and the retail was $35 lower."

"To make ColecoVision even more attractive the company gave away with 
 each unit a $35 Donkey Kong cartridge.  "Donkey Kong was a very 
 serviceable gorilla," says Greenberg.  "Once we convinced the consumer 
 of the merits of the hardware, Donkey Kong pushed him into buying.""

"Another popular feature has been ColecoVision's expandability. 
 Accessories like the $55 Turbo module, a steering wheel, gas pedal, 
 and gear shift used to play a road racing game, can be plugged into 
 the console.  The company's $60 Atari adapter enables ColecoVision to 
 play Atari VCS-compatible cartridges.  Atari doesn't approve - it's 
 suing Coleco for $850 million, charging patent infringement - but game 
 addicts do.  Coleco sold 150,000 Atari adapters in just two months.  
 Coleco's latest add-on, the Super Game module, was shown at last 
 week's American Toy Fair. It adds more memory to ColecoVision and 
 provides additional play variations."

"Coleco's software approach was to go after licensed arcade games and 
 to make cartridges for Atari's VCS and Intellivision in addition to 
 it's own game player.  Although Coleco hadn't built a single 
 ColecoVision when it was negotiating licensees in 1981, the licensers 
 liked Coleco's plan to make products for all three leading game systems.  
 Coleco reached agreements with five firms, landing nine hit arcade 
 licensees. Last year the company sold eight million cartridges."

"Flush with last year's successful foray in video games, Arnold Greenberg 
 predicts even more good news is on the way.  "We are a terror in the 
 marketplace," he boasts.  Greenberg proclaims that Coleco will increase 
 it's market share in video game players this year from 8% to 25%, 
 supplanting Mattel as No. 2."

"Achieving such lofty goals may be difficult.  Coleco last year paid 
 only $250,000 for the rights to Donkey Kong, but Atari later had to pay 
 an estimated $21 million to license E.T. for it's coin-operated and 
 home video games.  Late last year Coleco reached an agreement with the 
 game maker Centuri for licenses to three arcade games: Phoenix, 
 Vanguard, and Challenger.  Then just before the contract was to be 
 signed, Atari won the license by making a higher offer.  Parker 
 Brothers also outbid Coleco for the Popeye license.  "Coleco's position
 is still not assured," says Barbara S. Isgur, a security analyst at Paine
 Webber.  "They were helped last year by the phenomenal success of Donkey 
 Kong.  What will they do for an encore?"

"Arnold Greenberg remains optimistic. He notes that Coleco has already 
 signed license agreements to bring out 30 new games by year-end.  In 
 January, Coleco made CBS the principal foreign distributor for it's 
 products.  In return Coleco will begin developing and marketing for 
 ColecoVision home video cartridges licensed by CBS from Bally, a major 
 arcade game maker."

Unfortunately, the ColecoVision suffered the same fate as the rest in
the great video game shake-out of 1984.  Coleco's unsuccessful bug-ridden
ADAM computer only complicated the problem.  Some believe if it wasn't
for Coleco's Cabbage Patch dolls, they would have completely disappeared.
Even the Cabbage Patch dolls couldn't keep Coleco going forever, though;
the company went under for good a few years later.  Ironically, Mattel
(the producers of Intellivision) now own the rights to the Cabbage Patch
dolls.

Coleco stopped production of the ColecoVision in 1984.  Their last few
titles (Illusions, Spy Hunter, Telly Turtle, and Root Beer Tapper) were
barely seen in stores.  Soon after that, Telegames bought much of
Coleco's stock and even produced a few titles of their own that didn't
reach the shelves before the shake-out.  As recently as 1991 a mail
order electronics store was known to sell ColecoVision motherboards
and joysticks.

When Coleco left the industry they had sold more than 6 million
ColecoVisions in just two years, even with the last year being troubled
by the shake-out.  Many in the industry believe if it wasn't for the
videogame crash of '84, that Coleco could have gone through the 80's as
the system of choice, especially with its proposed Super Game Module.  It
was clearly beating Atari and Mattel, but just didn't have the installed 
base to last out the crash.

What really distinguished the ColecoVision from other systems of the era
was its 32 sprite capability.  It made it easier to design sprite intensive
games like Slither.

Scrolling on the Coleco was sort of chunky because they did not have special
hardware for scrolling like the Atari units did - but some games (notably
Jungle Hunt and Defender) _do_ manage to scroll well, so there was a
software workaround of some kind. 

All Coleco cartridges, and many third party titles, incorporated a
patience-testing twelve second delay before the game select screen showed
up.  One story commonly cited (and apparently mentioned in Electronic
Games magazine at the time) is the following: before ColecoVision reached 
the marketplace, Coleco invested heavily in advertising for the system, 
building up significant demand.  The problem was software support.  Few 
programmers knew the ColecoVision's quirky assembly language, and there 
wasn't time to train more.  So the engineers at Coleco designed an emulator 
that allowed progammers to code in a far more common and well known 
language, Pascal.  Coleco then hired programmers familiar with Pascal to 
design software for the ColecoVision, and thus were able to provide 
software to meet the demand.  The only problem with the scheme was the 
twelve second delay the emulator caused while starting up.  

As good a story as this makes, it's incorrect.  The real reason behind
the twelve second delay is a loop in the ColecoVision BIOS - the delay
was purely intentional.  The way companies such as Parker Brothers,
Activision, and Micro Fun avoided the delay was to simply bypass the 
ColecoVision BIOS. - JC, 08, 10, 12, 27, 29

Expansion Module #3 (Super Game Module - wafer version) by Coleco.

  With 30K RAM and 128K "microwafers" shaped like miniature diskettes. The
  games were to have intermissions, high-score lists, and extra levels.
  It was to be packaged with Super Donkey Kong; later, that was changed
  to Super Buck Rogers and Super Gorf.  It could have been an excellent
  addition to the ColecoVision system allowing you to play your old carts
  and the new Super Games, but Coleco decided to turn it into the ADAM
  computer. - JC, 25
  
  Kevin Slywka submits the following: 

  The following is a quote from the article, One million A.C.(after 
  ColecoVision)  Brown, Michael William;  Electronic Fun: Computers and 
  Games; June 1983

  -Note: The article contains several screen shots and a what appears to be 
  a mock up of the Super Game and several game wafers.

  "...the Super Games are stored on mini-cassettes (which are about 
   the length and width of a business card) called Super Game Wafers...
   the module has a magnetic micro-tape drive mechanism behind a slot in 
   the front left panel.  Inside the wafers is approximately 50 feet of 
   specially formulated magnetic tape about an eighth of an inch wide."
  (Brown p41)

  Brown claims to have played the system for 8 hours over two different 
  days.  Load time for the wafers is clocked at about 10 seconds.  Super 
  Games Brown tested:  Super Donkey Kong, Super Donkey Kong Jr., Super 
  Smurf Rescue in Gargamel's Castle.  Brown further notes better colors 
  and additional levels in all three games.  Planned titles included:  
  Zaxxon, Buck Rogers Planet of Zoom, Time Pilot, Turbo and Sub-Roc.  
  Brown also notes the ability to enter your initials for high score, 
  which is then stored on the tape.  

  In Video Games Magazine(Feb.'84) an article on the Texas Instruments 
  Compact Computer 40(a peripheral for the TI 99/4A) mentions the tape 
  wafers meant for the Super Games: "...this system uses the Entrepo 
  floppy wafer system that is in use elsewhere, and was almost part 
  of Coleco's Super Game Module and ADAM."

  The Super Game Module appeared to not have a realistic chance of 
  success at Coleco Industries.  In an interview of Coleco president, 
  Arnold Greenberg, by Steve Bloom (Video Games, Oct. '82) Bloom 
  paraphrases Greenberg as saying, "...it is Colecos resolve to market 
  a keyboard (Module #3) some time next year."   In Electronic Games
  (Jan. '83): Test Lab (Cohen, Henry B.) writes that, "...Coleco is 
  working on a keyboard and Ram Cram for ColecoVision which should 
  turn the system into a full-scale, high powered home computer system."  
  Clearly Coleco intended to develop a ADAM-like computer all along, 
  but the question remains as to why they decided to develop the Super 
  system in the first place.  If the Super module had been released it 
  likely would have insured Colecos success for at least a while longer.  
  Although given the cynicism of magazine writers and consumers after 
  the Super Module failed to appear it is uncertain if it would have 
  been enough to save Coleco from its eventual fate.  

  Description of the pictures in the Electronic Fun magazine article(kws):

  The module shown appears to be the real thing(although almost 
  certainly a mock-up) with a slot for the super tape wafers on the left 
  side of the module(even a small slot that corresponds to the door on the 
  super wafer can be seen).  A small LED is near the super wafer door, 
  probably to indicate a read\write or power light.  The "Expansion Module 
  Interface" is on the lower right of the module.  The top of the unit has 
  the ColecoVision face-plate and a reset button on the far right.  

  Below the module three wafers are shown:  They have the appearance 
  of micro-cassettes, they are all black and appear to have a door on 
  the left rear of the wafer.  Super Donkey Kong, Super Donkey Kong 
  Junior, and Super Smurf (in fine print: Rescue in Gargamel's Castle) are 
  represented.  There is a game package which bears a striking resemblance 
  to a CD jewel case(although it appears to be made of vinyl) has Buck 
  Rogers Planet of Doom on the cover.  The by-line on the case states:

	"For use with ColecoVision Expansion Module #3"
	"AN ADVANCED VIDEO GAME THAT"
	"PLAYS ALL SCREENS INCLUDING"
	"BEST SCORES AND INITIALS!"

  The vinyl game case carries a part number of "#2645" - 25

Expansion Module #3 (Super Game Module - CED version) by Coleco.

  A second Super Game module was also rumored.  It used a format called 
  CED, using video records - vinyl records with much finer grooves, 
  stored in cases so as to avoid contact save by the needle of the system.  
  In an interview with Ralph Baer, who worked on this system, he said it 
  was really zippy and in some respects better than CDROM. - 11, 34

  CED stands for Capacitance Electronic Disk system, and was pioneered
  by RCA.  RCA used this technology in all of there CED video disk players,
  which competed with the Laserdisc format until 1985 when RCA discontinued
  all of its players.  Coleco chose the CED format because RCA could create
  a computer controllable random access machine that was very affordable.
  The Coleco CED system would have come with two major components: the Coleco
  "controller" Module (#3) that plugs into the front of the system, and
  the RCA/COLECO CED player that connected to the Module and the T.V. set.
  Reportedly the price would be around $395-$495 for a complete set-up.
  Interestingly, the Coleco CED system would still play all of RCA's
  movie and music video disks, which was a big selling point for RCA.
  So you would have a Video Quality arcade system, and movie player - all
  in one.

  From Video Games and Computer Entertainment, June 1991:

  'Talk of the future reminds Baer of the aborted, ahead-of-its-time 
   project he launched in 1982.  The ideal interface, the ColecoVision 
   video game console and an RCA CED player.  "Things advanced to the 
   point that RCA actually made a few CED peripherals.  Then along came 
   the ADAM computer and ended it all.  What I'd like to see is not 
   going to happen."  He'd like to see CED revived, instead of the 
   industry going to CD.  He worries that CD will fail to deliver the 
   full-motion video that people expect.' - 12

ColecoVision (THE ORIGINAL VERSION) by Coleco.

  Remember seeing the first "glimpses" of the ColecoVision system in
  Electronic Games magazine?  The first pictures of the system showed
  a much more attractive looking system than what we got as a final
  product.  The system itself had a white faceplate where the ColecoVision
  logo appears now and the controllers were very different.  They had blue
  side buttons, orange pound and star keys on the keypad, and the finger
  rollers that were later introduced on the Super Controllers.

  The finger rollers, which were to have been located between the keypad
  and joystick, were supposed to be available for use as either speed
  controllers, or as a paddle controller.  They were dropped at the last
  minute, though if you open up a controller you can see the schematic for
  it on the circuit board. - 07

  The finger rollers shown in Daniel Cohen's book "Video Games", page 57,
  are located beneath the keypad. - 24

Intellivision Adapter by Coleco.

  Coleco had plans for an adapter that would play Intellivision cartridges.
  Supposedly there are several working prototypes of this adapter that were
  shown at electronic shows. If Coleco would have only gone through with
  production, the ColecoVision would have been able to play Intellivision,
  2600, and ColecoVision cartridges! - JC

Modem by AT&T/Coleco.

  Not to be confused with the ADAM modem, which does exist.

  An article in Newsweek, September 19, 1983, on page 69 announced the
  following:

  'American Telephone and Telegraph Co. and Donkey Kong?  An unlikely
   combination, perhaps, but one that became a reality last week when the
   venerable communications giant hooked up with Coleco Industries, the
   videogame maker, in a join effort to make entertainment software
   available by telephone to 25 million owners of video games and home
   computers.'

  'Under the plan, AT&T and Coleco will develop a "modem", an electronic
   device that will connect a home computer or video game by telephone to
   a central data base.  Coleco will supply the software programs, such
   as Donkey Kong or two of its other popular video games, Smurf and
   Zaxxon.  The service will be offered sometime next year for about $20
   a month; the modem is expected to cost $100.' - 13

Sensory Grip Controller by Coleco.

   The Super Action Controllers were supposed to have a sensory feature,
   so that when (for example) Rocky threw a punch in Super Action Boxing,
   you would feel it in the handle. - 13

3.3) Review of the Telegames Personal Arcade		by James Carter

INTRODUCTION:

TELEGAMES produces and sells a ColecoVision compatible system called the
"Personal Arcade". The Personal Arcade was originally produced several
years after Coleco stopped production of the ColecoVision. It's very small
(12"x5"x1"), white, and comes with Nintendo-like gamepads. It uses a normal
sized power supply (6' cord) which is less than 1/2 the size of the
ColecoVision's ridiculously bulky one. It also comes with a game/TV
switchbox (10' cord) like the ColecoVision. It also contains two separate
expansion ports that were never taken advantage of.

COMPATIBILITY:

The ads and box say "Compatible with over 100 ColecoVision cartridges".
TELEGAMES operators claim that it is compatible with 95% of all the
ColecoVision cartridges, but won't provide a list of which ones it won't
work with.  So far I've come up with 10 after testing it on 65 cartridges.
Actually, *all* the cartridges work, it's just that the "Personal Arcade"
uses different joystick wiring and any cartridge made specifically for
the Super Action Controllers, Driving Module, or the Roller Controller
will be unplayable, among others.  In fact, regular ColecoVision or Atari
compatible joysticks cannot be used on the Personal Arcade either.

GAMEPADS:

The gamepads are 1 3/4" x 4 3/4" and nicely fit into the sides of the
unit.  The cables are 3 feet long and stiffer than normal.  A personal
grudge is the fact that the cables attach to the side of the gamepad
instead of the rear, making it harder to comfortably grasp.  They are
also slightly too small and cheaply made in my opinion.

KEYPAD:

A single keypad is built into the unit and the buttons are a smaller
3/8"  square, compared to the 5/8" square of the normal ColecoVision
controller. It is made of a thin membrane that works with the slightest
touch. The keypad has no frame like on the ColecoVision controller.
It looks like the following:
      1 2 3 4 5 *
      6 7 8 9 0 #
This changed keypad size and format means overlays cannot be used. It
also means it is very difficult to play keypad intensive games where
quick reflexes are needed.  Now you must take your hand off the gamepad,
and look down to press the right key, instead of the ColecoVision
joystick where you just move your thumb without looking.

NON-COMPATIBLE LIST:

The following are unplayable on the Personal Arcade due to controller problems:
  Fortune Builder (needs 2 separate keypads in 2-player head-to-head mode)
  Front Line (Super Action Controller game)
  Rocky Super Action Boxing (Super Action Controller game)
  Slither (Roller Controller game)
  Super Action Baseball (Super Action Controller game)
  Super Action Football (Super Action Controller game)
  Super Action Soccer (Super Action Controller game)
  Super Cobra (2nd button "bomb" doesn't work)
  Turbo (Driving Module Game)
  Victory (Roller Controller game)

KEYPAD INTENSIVE LIST:

The following do work perfectly on the Personal Arcade, but are difficult
to play because of the need for very quick keypad presses:
  Aquattack
  Blockade Runner
  Mouse Trap
  Spy Hunter
  War Games

BUILT IN GAME:

The Personal Arcade comes with a built-in game called "Meteoric Shower".
A decent shoot'em up game in which you have a ship in the middle of the
screen and you shoot waves of enemy ships that attack from above and below.

DISPLAY:
The Personal Arcade removes the famous multi-colored "ColecoVision"
opening screen from all of Coleco's cartridges, replacing it with a green
background and Japanese writing, with the words "1986 BIT CORPORATION".
Other publisher's opening screens are unaffected.

FINAL THOUGHTS

PROS:

The best thing the personal arcade has going for it is the price. Only
$39.95 for a brand new system, with a decent built in game, and you get
to choose 1 brand new cartridge ($19.95 or less, about 40 to choose from)
also.  If you prefer gamepads, then that is a plus also.  The smallness
of the system makes it much easier to store and move around.

CONS:

If you have a perfectly working ColecoVision there is really no reason
to buy the Personal arcade, unless you want a back-up system.  (...or you
have a burning desire to play Meteoric Shower. - JH)  The gamepads are
less than desired, and no other joysticks can be used in their place.
The fact that you can't use Super Action or Roller Controller games
(not to mention others) is a big thumbs down for those that already
invested in those controllers and cartridges.  The keypad on the system
may be great for choosing levels, but is a pain to use keypad intensive
games.

NOTE: Telegames lost all of their Personal Arcade stock to a tornado
      in April, 1994.

3.4) Hardware Tidbits

Atari Touch Pad / Children's Controller / Star Raiders Controller -

    The following buttons and/or combinations of buttons correspond to
    various inputs on the ColecoVision:

    DESIRED      PRESS THIS ON 
    COLECO KEY   ATARI TOUCH PAD

    Left button  
    Right button 1 + 3, or 4 + 6, or 7 + 9, or * + #. - 20
 
CBS ColecoVision -

    Looks and operates just like my 'standard' ColecoVisions, but the 
    metallic faceplates are different.  On top, it says "1 / 0" instead of
    "Off / On", and the front plate reads:

    ________________________________________________________________________
    CBS  Coleco   Video Game/Home Computer System     [expansion slot]   CBS
         Vision                                                      
    Electronics
    ________________________________________________________________________

    CBS Electronics bought out the Coleco rights when Coleco bit the bullet.
    They marketed mostly in Europe. You can find most if not all of the Coleco
    games with a CBS label.  They are all or mostly all PAL games.  However,
    since the ColecoVision doesn't care, it doesn't matter.  Plug them in and
    they play like NTSC! - 20, 22

Champ Adapter -

    A near exact duplicate of the Coleco Keypad, minus the upper half that
    contains the joystick.  Instead it has a 9-pin slot so you can plug
    in your favorite joystick and still have use of the keypad.  It also
    can double as a joystick extension cable since the Champ Adapter cable
    is 6' long. - JC

Co-Stickler -

    Plastic "snap" on joysticks for the standard ColecoVision 
    controllers. - JH

Expansion Module #1 -
    
    The following Atari 2600 cartridges are incompatible with the 2600 
    Adapter:

    Texas Chainsaw Massacre - JH
    Most Tigervision titles - 19 (but Miner 2049'er works - JH)
    All Supercharger games - 19 (will work, but only if cover of 
	expansion module has been removed) - 26

Expansion Module #1 Adapter -

    This device plugs into Expansion Module #1 (2600 Adapter) to allow
    some Atari 2600 cartridges which have compatibility problems to be
    played.  Supposedly it was only sent through the mail to those
    customers who called Coleco with complaints of 2600 cartridge
    problems. - JC

Expansion Module #2 -

    The driving controller can be used to play Victory, which officially
    requires the Roller Controller. - 46

Grabber Balls -

    They're red balls of a stick that snap on the ColecoVision controller,
    making it more arcade-style.  Work *fantastic* when locked into the
    Roller Controller, and played with Robotron on the 7800. - JC

Joy Sensor -

    A lot like an Intellivision II controler.  Has a membrane kepad area
    and a membrane joystick, plus what appear to be rapid fire controls 
    that might be variable.  Well made. - 41

Perma Power Battery Eliminator/AC Adapter -

    Replaces the batteries in Expansion Module #2 (Driving Controller) - JC

    This is a _weird_ device.  Since the only way to power the unit is with 
    batteries (there's no alternate for a power source, so the connection
    is required), the "Battery Eliminator" is shaped like batteries. - JH

Power Stick -

    A great joystick for non-keypad, one button games.  Having the keypad
    and second button above the joystick makes it awkward for those games,
    though. - JH

Roller Controller -

    To use the Roller Controller on a game which doesn't require its use
    (such as Centipede or Omega Rage), leave the Joystick/Roller switch
    in the Joystick position. - JH

    Driving Module games can be played with the Roller Controller by
    doing the following:

	1) Switch the setting to "Joystick".
	2) Choose the game you wish to play.
	3) Switch the setting to "Roller Controller".
	4) Go.  The leftmost button acts as the accelerator.

    Direction can be changed using the joystick in some as-yet
    undetermined manner. - 24

    You can get very strange behavior by using the roller controller 
    for joystick games?  Try wiggling it around while playing Smurf 
    and you can move above or under the proper "ground" area
    so that none of the enemies can kill you! - 14

Super Sketch Pad -

    Came in a box with a black background and a horizontal rainbow across 
    the top, marked "Super Sketch".  In addition to the ColecoVision
    version, there were Commodore 64, Atari 8-bit, & TI 99/4A models.
    The ColecoVision version has a silver sticker on the top right corner
    that says Model G2500 For Use with Colecovision.  The Sketch Unit 
    itself is white with a brown plastic piece used for the drawing.  One 
    of the strangest things about it is that it does not plug into the 
    joystick port.  The cable is attached directly to the right side of 
    the cartridge.  The cartridge label is mostly silver with Super 
    Sketch with the horizontal rainbow with it.  

    The sketch unit it has 5 controls.  Two "Lift" buttons, one on each 
    side, allow drawing to be turned off.  "Select" allows selection of
    colors and menu items on the left side of the screen; "Menu" brings
    the menu up and/or removes it.

    The program itself say Super Sketch while fluctuating through different 
    colors upon power-up.  Just below that it says:

		Copyright 1984 Personal Peripherals, Inc.  
				Irving,Texas   
			      By: Steve Roubik  
			   Press MENU to proceed.

    The program really is nothing more than a doodle program.  Menu
    options are:

	Clear
	Swap
	Expert
	Brush

	(The 16 Colors)

	Eraser
	Draw
	Fill
	Show

    It comes with a large white envelope that says Super Sketch starter 
    kit.  Inside is the owners manual, quick reference card, 6 drawings 
    to trace with, and a warranty card. - 42

Telegames Personal Arcade -

   The Personal Arcades were originally made by the Bit Corporation, and
   marked as DINA units with a second cartridge slot for some unknown
   purpose. - 30

   The joypads that come with the Personal Arcade are 2600 compatible;
   they also have an irksome quirk for anyone used to the ColecoVision:
   they're reversed (i.e. right is left, left is right).

   Besides the games listed above, Smurf Rescue in Gargamel's Castle is
   incompatible with some Personal Arcades, and the 2600 Adapter will
   not work due to power and RF cable positioning.

   The pause switch is incompatible with ColecoVision cartridges, so
   it is apparently used by cartridges which go in the second slot. - 14, 52

   At least two different version of the Personal Arcade (with different
   power supplies) exist. - JH

4.2) Carts believed -not- to exist

Coleco was infamous for not putting out advertised cartridges. Several
of the carts were shown in the catalog that came with the ColecoVision.
It is not known if the screen shots shown were simple artist renditions,
or if somewhere an actual demo or prototype of the cartridges exist. - JC

The following cartridges, put out by the listed manufacturer, reportedly
do not exist, even as a prototype or demo cart.  Solid evidence of their 
existence would be greatly appreciated.

4.3) CBS product numbers - 55

Coleco games for the European market were produced by CBS Electronics in
England.  The carts have the same size as the US ones, but the upper end
has a different shape.  There is a finger-thick indentation on each side,
probably to make it easier to get the cart out of the system slot.  The 
labels are black; on the upper half there's the CBS/Colecovision character 
and the name of the game.  Below is a white box with a lot of writing, 
copyright and production information, the model number (4Lxxxx), and often 
the sentence "for use on pal-tv-system only". Sometimes the labels are 
multilingual.

4.3) Cartridge Tidbits, Tips, and Easter Eggs:

Alcazar the Forgotten Fortress -

    This game was designed by Activision, but never released by them.
    All known copies were released by Telegames, but with a combined
    Activision/Telegames label.

B.C.'s Quest for Tires II: Grog's Revenge -

    The following secret codes can be used to change levels: - 17

    Mountain 1:   2,2 in cave 3
               	  3,3 in cave 5
		  4,4 in cave 1
		  5,5 in cave 1

    Mountain 2:	  2,2 in cave 1
		  2,3 in cave 1
		  4,4 in cave 1
		  4,5 in cave 5
		  6,2 in cave 10
		  7,8 in cave 5

    Mountain 3:	  3,1 in cave 5  (hint: "as easy as pi", ie. 3.1415925)
		  4,1 in cave 7
		  5,9 in cave 8
		  2,5 in cave 8

Blockade Runner -

    Need the manual - 01

Bump 'n' Jump -

    Pales in comparison to Intellivision version, with off-key music,
    washed-out colors, sluggish control, unforgiving collision detection,
    and other errors and annoyances. - 20

BurgerTime -

    After completing the first round of boards, the game speeds up.  Thus, 
    pepper is in short supply as well as your patience.  Includes six
    boards, two _more_ than the arcade version (the Intellivision version
    actually includes still two more).  Based upon the arcade game by Data 
    East. - 24

Cabbage Patch Kids Adventure in the Park -

    Prototype is an enhanced version of the released product, not a
    predecessor. - JH

Carnival -

    Shoot the hardest targets (pipes and letters) first; once you get
    down to a few targets the ducks come out in volume, leaving little
    time or ammunition to shoot the harder stuff. - JC

    Based upon the arcade game Sega. - 24

Centipede -

    Atarisoft made a perfect port of Centipede for ColecoVision.  With 
    roller controller, you have the arcade version at home!  Based upon
    the arcade game by Atari. - 24

    In the Centipede cart rom, there is a message at the end of the code:

        IF YOU ARE READING THIS, AND YOU WORK AT COLECO,        
	THEN PLEASE TELL GEORGE KISS I SAID HELLO.  THANKS.

                                   SINCERELY, LARRY CLAGUE

        PROGRAMMED BY:              L CLAGUE
        GRAPHICS AND ANIMATION BY:  L CLAGUE
        SOUND DATA SUPPLIED BY:     A FUCHS
        START DATE:                 04/20/83
        COMPLETION DATE:            08/23/83 - 31

Chess Challenger -

    From the catalog: - 24

    Chess Challenger by Fidelity (Chess Challenger (C) 1977)
    Strategy Game Cartridge
    #2438
  
    This game uses the World Champion Chess programs by Fidelity.  Plan 
    your defense with care -- the computer is a formidable opponent.  But 
    don't get too confident -- he'll never play the same way again!

Chuck Norris Superkicks -

    Also released as Kung Fu Superkicks, by Telegames. - JC

Congo Bongo - 

    Based upon the arcade game by Sega. - 24

Cosmic Avenger -

    With some skill, you can make the homing missile that come at you
    strike the UFO's by dodging the missile so it goes in front of you,
    then moving up and down, using it like a guided missile. - JC

    For a completely different gaming experience, trying seeing how long
    you can survive using bombs _only_. - JH

    Based upon the arcade game by Universal. - 24

The Dam Busters -

    This game is damn near impossible without the manuals - 01

    Survival tips:

    Don't fly over the icons on the map.  These are German bases that
    will throw up a bunch of flak.
 
    Don't let your engines overheat, turn down the throttle after takeoff. 
 
    If an engine catches fire extinguish it and shut down the 
    corresponding one on the other wing.  If you don't the Lanc. will
    be difficult to control.  Don't do this a second time.
 
    You must come in at a certain altitude and airspeed to drop the bomb.
    Don't forget to get the bomb spinning or the indicators will not
    come up on the pilot's window.
 
    Be certain to retract the landing gear after takeoff.
 
    To shake fighters, try a corkscrew maneuver (downward spiral). - 17

Dig Dug -

    Programming of this game was completed. - 53

Defender -

    Since the ColecoVision could not handle scrolling very well due its 
    electronic design, the scrolling leaves Defender to be desired.  
    However, it keeps true to the Williams arcade game. - 24
 
Donkey Kong -

    Move Mario up the first broken ladder then bring him back down, walk
    him to the left so that his back is almost touching the same broken
    ladder, and then move him a step of two to the right and jump.
    Depending on the version you have, he'll fall through the bottom and
    land in screen 2, or after several seconds he'll appear on the top
    girder next to Kong. This apparently doesn't work with all versions
    of the cartridge. - JC

    In the 3rd screen, get to the top right hand part of the screen where
    the purse is. Below is a short ladder, get right above it and wiggle
    up & down, you'll fall through the metal floor. - JC

    When climbing up or down any ladder, you can move at super speed by
    pausing momentarily (allowing the joystick to center), and then
    continuing your climb. - JC

    Perfect port of the original game except for two flaws.  First, Donkey 
    Kong is on the wrong side of the first board (easy for anyone to pick 
    up).  Second, there is no mudpie level which means the rivet and 
    elevator (with no "bouncing springs") levels are repeated.  Based
    upon the arcade game by Nintendo. - 24

    You can score for jumping when underneath a rolling barrel.  On the
    fourth girder (one level below Donkey Kong), wait until a barrel one
    level above comes to the lower end of the girder.  As it comes across,
    follow it, and jump while underneath it. - 24

    On the elevator screen, go up to donkey kong instead of climbing the 
    ladder.  He won't kill you; you could climb the second ladder and 
    jump around him and make his face turn brown. - 48
 
Donkey Kong Jr. -

    Uses the same music for the key-n-lock level as used for the final 
    level on Popeye for ColecoVision.  Based upon the arcade game by 
    Nintendo. - 24

    In the screen containing pelicans, you can actually climb through
    the dirt.  To do so, get underneath a patch of dirt, and climb all 
    the way up to the dirt.  At that point, move Donkey Kong Jr. left,
    right, and left again.  You can then climb right through the dirt. - 32

    On the springboard birds screen, jump to the top ledge on the right 
    of the screen, and approach the gap.  Walking off the ledge, Junior
    grabs an invisible vine that let you climb up to the celing in 
    midair. - 48

Dot to Dot Zot! -

    Originally created for the Nabu Home Computer network, a ColecoVision
    conversion was rumored but never completed. - 17

Dragon's Lair -

    Right before the crash, Coleco had the rights to Dragon's Lair, and
    was going to release an expansion unit to let you hook up an LD
    player.  The idea was the controller would be the ColecoVision, and
    you could play Dragon's Lair in its entirety. - 16

    A version of Dragon's Lair was released for ADAM. - JH

Dungeons & Dragons IV -

    The Intellivision D&D game then in development, Tower of Mystery,
    was the third D&D game from Mattel, so apparently this game was
    envisioned as an original.  Started 11/28/83. - 36

Epyx games -

    Two case variants, one has a normal rounded case end and the other has
    a tapered end much like Imagic carts.  Gateway To Apshai is normally
    the regular case and the other two normally have tapered cases." - 01

Escape From the Mindmaster -

    Of note: the startup screen is an EPYX screen, not an Arcadia or
    Starpath screen, so this effort apparently occured after Starpath
    had been acquired by Epyx. - 5

Facemaker -

    It's Mr. Potato-Head on a cartridge! - 01

    Also released as Make-A-Face. - JC

Flashlight -

    Conversion of an Intellivision/Atari game then in development.
    Scheduled start: 12/19/83. - 36

Flying Brassieres -

    Never intended for release, this prototype is actually a privately
    burned variation upon Moon Patrol, with a different variety of 
    objects (including bras) to shoot at. - 22

Fortune Builder -

    The mother of all Sim* games!  But you need both the manual and the
    "Strategy Guide" to play - 01

    And the overlays certainly don't hurt, either. - JH

Frenzy - 

    Pressing "#" during the game resets the game. - 24

    Killing Otto in the Big Otto maze is a deadly mistake - Big
    Otto sends out hordes of super-fast Ottos to get you. - 24

Frogger -

    Perfect port of the arcade game by Sega. - 24

Frontline -

    You can get away with using a normal controller by hitting 1-2-3 at
    once on the keypad to launch a grenade/get into the tank - 01

    You can move through the holes in the wall by rotating and pushing
    forward at the same time. - JC

Galaxian -

    The following dedication is coded into the ROM for the cart:

    DEDICATED TO THE ONE I LOVE
    I LOVE YOU JENEANE (sp?) - 08

Gateway to Apshai -

    Manual helpful but not necessary - 01

Gorf -

    Loses points for not having the "Galaxian" stage like the arcade
    game - 01

    Based upon the arcade game by Bally/Midway. - 24

Horse Racing -

    From the catalog: - 24

    Horse Racing by Fidelity (Original copyright is (C) 1982)
    Casino Game Cartridge
    #2442

    They're off and running!  Watch the board as the odds change.  The 
    horses start out of the gate -- then jockey for position on the 
    straightaway.  Which horse will win ... place ... show?  For the next 
    race, the computer changes the entries and if you want, even the 
    track conditions!  It's a different race every time!

Hydroplane -

    A point-of-view speedboat race, based on an Intellivision game in
    development at the time.  Program start 11/21/83. - 36

Illusions -

    Very surreal game once you figure out what to do... - 01

    And it makes -no- sense until you do... - JH

Journey -

    In 1983, Electronic Games magazine reported that Coleco had purchased
    exclusive rights to the Bally/Midway Journey arcade game (not to be
    confused with Journey Escape for the 2600). - 38

Joust -

    Programming was completed for this game. - 53

    I've had one report that Joust was released, but absolutely no
    independent confirmation of this. - JH

Kung Fu Superkicks -

    Also released as Chuck Norris Superkicks, by Xonox. - JC

Lady Bug -

    This is (IMHO) the BEST arcade conversion available on the 
    ColecoVision. - 18

    Based upon the arcade game by Universal. - 24

Linking Logic -

    Imagine this: a man on a pedestal sitting on the left side of the TV 
    screen.  You, his faithful fowl pet, are sitting on the other side on 
    a similar pedestal at the same height.  Your mission: help your master 
    make it through the room maze using parts lying around.  Can you fly 
    around placing the parts in the right spots before your master sets foot 
    into the maze?

    Like Sierra On-line's "The Incredible Machine," you must place the parts 
    (such as a ladder or crossover board) to help your master safely pass 
    through the maze.  You have a limited amount of time, though, because 
    the pedestals raise up every few seconds.  When it gets to the top floor, 
    your master will go through the maze. 

    Designed by Freida Lennekerker. - 24

Looping -

    Similar to the later game, Sopwith, for PC, you fly a plane around 
    the screen and shoot at things.  What Sopwith lacked in graphics, 
    this game lacked in gameplay.  Based upon the arcade game by Venture
    Line. - 24

Magic Carpet -

    Scheduled to begin 2/6/84.  Since the Nice group continued working 
    after 1/20/84, it's possible that a playable version of this game 
    was developed. - 36

Make-A-Face -

    Also released as Facemaker. - JC

    Listed as a pirated version in the Digital Press Price Guide. - JH

Masters of the Universe: The Power of He-Man -

    Programmed by Steve Roney, based upon the original Atari version
    of the game.  The game was completed just before Mattel Electronics
    closed down, but was never released. - 36

Masters of the Universe II -

    Being programmed by Eric del Sesto based upon the original 
    Intellivision version (which was never released by Mattel, but
    instead reworked by INTV Corp. using different characters and
    released as Diner, a sequel to BurgerTime).  Unfinished. - 36

Meteoric Shower -

    Not released as a cartridge, the game is only available in the built
    in version that comes with the Telegames Personal Arcade. - JH

Missile Command -

    A playable version was never developed.  Only a title screen was 
    created. - 53

Mr. Do! -

    If you drop two adjacent apples and get crushed by the first one, you
    are squished but don't die. You then have to restart the game. - JC

    The pause button is "*".  Hit it once for a blank screen with 
    repetitious music; hit is twice more to begin play again.  Based 
    upon the arcade game by Universal. - 24

    You can fire through thin walls at short distance in Mr. Do!, and
    can freeze all enemies by taking the "treat" in the middle when the
    Extra apple at the top of the screen is on a red letter. - 54

Mr. Do!'s Castle -

    In order to get the most alphamonsters in "Mr. Do!'s Castle", hit 
    one or two of the key blocks with your hammer as you cross the 
    board.  After destroying all the monsters except for two or three, 
    you can hit the last key block and run up to the top of the board 
    and stand near the door.  Wait for the unicorns to get near you and 
    get the door "prize" and hammer away!  This was an old arcade trick 
    I used quite frequently, and it still works for this game.

    In "Castle", red unicorns are the tamest ones.  Green unicorns are a 
    bit wilder, and both red and green unicorns can be knocked down a 
    level.  However, the blue unicorns are the meanest, and a lone 
    unicorn will double into two blue unicorns if it gets stuck in a 
    hole or cannot find you.  This can work to your advantage if you 
    have reached the door "prize" and let a lone unicorn get stuck in a 
    hole.  When it doubles and turns blue, they will immediately come up 
    to you at the top of the castle so you can grab the prize and knock 
    two of the letters out really quickly.

    "Castle" is the best arcade translation of all the ColecoVision games.  
    It also proves that Coleco's version of Mr. Do! could have been better,
    looking like a rush job in comparison.  However, both Mr. Do! games 
    are worth getting because they have a lot of replayability in them. - 24

    Most boards have sections with skulls such that you can kick a ladder 
    away, leaving only one path for the unicorns to approach from.  To take 
    maximum advantage of these setups, do the following:

    1) Knock out the frontmost skull (on the side enemies will approach 
       from).
    2) Hammer the frontmost cherry.
    3) As red unicorns approach, simply knock them through the hole.  
       There's no need to waste the skull traps on them, since they are 
       easy to deal with.
    4) When a lone green unicorn lands in the hole, knock it through.  It 
       will turn purple, but don't worry!  Back up to the next cherry, and 
       hammer it as the newly formed purple unicorn dashes forward, crushing 
       it.
    5) Back up and repeat the process until there are no cherrys left, 
       several green unicorns approach at once, or one or more purple 
       unicorns storm into the trap.  As soon as there are purples 
       approaching, continue retreating and hammer free any remaining 
       cherries, then hit the final skull to kill all squirming purples 
       as well as any unicorns unfortunate enough to be standing below the 
       platform.

    With good timing, it is possible to hammer a unicorn that is rising 
    out of a hole just as the new block forms, and kill it (or knock it 
    back into the hole if it is a purple one).  This is helpful when you 
    are cornered in a tight spot.

    To maximize the number of letters you catch on any given stage, try the
    following strategy:

    1) Hammer two of the keys, leaving the key closest to the top of the 
       screen.
    2) Hammer as many holes as you can while luring the unicorns downwards, 
       until you have a free path from the third key to the magic door at 
       the top of the screen.  Avoid killing the unicorns unless necessary.
    3) Hit the final key, and immediately dash to the top of the screen, 
       turning the unicorns into letters.  The longer you wait after 
       grabbing the third key before touching the magic door, the shorter 
       the period of time that the unicorns will remain as letters.  
       Conversely, if you do it quickly, the unicorns will remain letters 
       for a very long time!
    4) The letters will flee towards the bottom of the screen.  Chase them,
       dropping down the holes you already made whenever possible (this is 
       quicker than climbing down ladders, and better yet you can land on 
       top of letters and squish them).

    With this method (even on the difficult levels later in the game), you 
    can easily grab 3 or more letters per screen.  It's even possible to 
    get a full "EXTRA" all on one stage! - 45

Mr. Turtle -

    From the catalog: - 24

    Mr. Turtle (TM)
    Action Game Cartridge
    #2432

    Mr. Turtle (TM) comes to life on the screen, but needs your help on his
    treasure hunt.  His goal is to collect the prizes that are located on
    both land and under water.  But -- each prise is guarded by an animal,
    some firece, some funny.  Mr. Turtle (TM) must outwit the creatures to
    obtain each treasure and score points.

Mouse Trap -

    Since there's no pause feature in this game, you can trap yourself
    in one of the rooms if you need a break.  You can also trap the cats
    in rooms to make it easier for you to do the maze. - JC

    The keypad gets in the way of the gameplay.  The 2600 version is more 
    fun because it has one button, but Coleco could have chosen to make 
    the doors open using one button and eating the biscuit being the other 
    button.  Based upon the arcade game by Exidy. - 24

Nice Ideas -

    At one time a division of Mattel Electronics located in Nice, 
    France.  Due to French laws, Mattel was not allowed to shut down 
    their Nice office on January 20, 1984 with the rest of Mattel 
    Electronics - instead, they were required to find a buyer for 
    the division.  The programmers stayed on the Mattel payroll working 
    on their games until finally the division found investors that 
    enabled them to buy the operation themselves, renaming it Nice Ideas. 
    They sold two of their completed Intellivision games to INTV Corp. 
    and three of their completed ColecoVision games (Bump 'n' Jump,
    BurgerTime and Illusions) to Coleco. - 36

Omega Race -

    If you use Roller Controller for the two play game, you will make both 
    ships mirror the other's actions.  One RC controls both ships!  Based
    upon the arcade game by Bally/Midway. - 24

    In a one play game, rotate your ship so that it points straight up
    or down, and thrust until you bump into one of the walls.  You will
    then keep bouncing between the top and bottom, and can rotate your
    ship toward the right hand side of the screen, and fire away.  Works
    well until you get to higher levels. - 54

Parker Brothers -

    There are two boxes used by Parker Bros.  One is the typical "boxed" 
    game with two box parts that open up to reveal the game and 
    instructions.  The other is a clone of the standard Coleco box with 
    Parker Bros. written on it instead. - 24

    Parker Bros. used the same serial numbers for their games around the 
    world with one exception--for foreign release, a "A" was added
    to the serial number of the game. - 24

Pac-Man -

    Has the same aspect ratio as the 2600 (and 5200 - JH) version; plays
    really well, and maintains all the bonuses and intermissions.  The title
    screen includes a neat dissolve-in of "Pac Man".  Atari did not
    release the cartridge because of their advertising campaign at the
    time, which boasted "you will only be able to play Pac-Man on the
    Atari!". - 53

    The _best_ home version of Pac-Man I've ever played.  Scores over the
    competition on the basis of:

	2600 - absolutely everything (no big surprise)
	5200 - better detail (the ghosts have eyes) and better control
	NES  - better control (which outweighs the aspect ratio and
	       attract screen advantages of the NES version in my opinion)

    Seems to be 100% complete and ready for release. - JH

Pepper II -

    Graphics are very similar to those of the unreleased Side Trak.  Based
    upon the arcade game by Exidy. - 24

Pitfall! -

    You can walk through some walls by jumping at them. - JC

PizzaTime -

    The _real_ sequel to BurgerTime, started 1/3/84.  Since the
    Nice group continued working after 1/20/84, it's possible that
    a playable version of this game was developed. - 36

Popeye -

    Very good port, but the characters needed a bit more detail (which 
    I'm sure the ColecoVision could have handled).  On the other hand, 
    this is the only port I know of which has the Sea Hag and Sweet Pea.
    Based upon the arcade game by Nintendo. - 24

Porky's -

    The cartridge shell looks like a bare Epyx/Spinnaker style case, with 
    a plain white rectangular hand written label.  Inside, there is a 
    standard board with 2 EPROMs.

    The start up screen is all blue, with a 1983 "Fox Electronics" copyright 
    notice, and skill options at the bottom of the screen.  According to a 
    guy who has the Porky's programmer for an instructor, he never made a 
    2600 port, so that was done after he had left.

    The game play is similar to the 2600, only with better graphics and 
    sounds (yes, the female showering looks more female).  The first
    Screen is the Frogger-like sequence in the same order, just with 
    improved graphics.  The second screen is the "pole-valut-over-the-lake" 
    screen.  You still have to build the ladder wrung by wrung; and Porky 
    is himself is walking around the ledges beneath the ladders.  Porky 
    is particularly well-animated--with a black ten-gallon hat, white 
    T-shirt, blue jeans, and a cigarette in his mouth.

    The third screen, the "girls shower room" had the girl scrubbing up
    in the shower, she was slightly more rounded and womanlike than the 2600
    version; the silhouette was dark gray, and the shower curtain light 
    gray.  When Mrs. Ballbricker comes after you, she is also well-done;
    with gray hair, a green shirt, and blue pants.  She also clearly has
    tweezers she is pinching in the air.  Only two different objects can 
    be retreived from the shower room to stop the objects in the 
    Frogger-like screen:  the detonator, and either a coil of rope or a 
    fork or a wrench.  These objects alternate for each row of the first 
    screen; the first object stopped the odd rows, the second the even rows.

    In the last screen, "The girders beneath Porky's", still had Porky
    walking around, making a nusciance out of himself, and it still had 
    those annoying arrows supposedly to point you in the right direction 
    to climb.

    The only problem with the game is that after getting past the locker 
    room screen to the screen underneath Porky's--you cannot go 
    anyplace. - 01, 43

Q*Bert -

    Just like the arcade game by Gottlieb. - 24

Q*Bert's Qubes -

    Very fun puzzle game.  As Q*Bert moves, he turns six-sided cubes 
    around.  To win a level, you need to match up tic-tac-toes of cubes.  
    The "Coily"-like mouse will chase you around the diamond playfield, 
    but will fall of if he lands on a turning cube.  Sam and Slick are a 
    real pain on the higher levels.  The pause button is "0".  Based upon 
    the arcade game by Mylstar.

    Level One -- Two sides orange, four sides blue
                 Win 1 tic-tac-toe

    Level Two -- Three sides orange, three sides blue (1st two screens)
                 Six colors (white, red, blue, orange, yellow, green)
		            (3rd and 4th screens)
                 Win 1 tic-tac-toe

    Level Three -- Six colors and win 2 tic-tac-toes

    Level Four -- Six colors and win 3 tic-tac-toes

    Level Five -- Six colors, win 1 tic-tac-toe, but you can undo 
                  completed cubes

    The label on the cart is the logo of Q*Bert's Qubes with no picture 
    of Q*Bert or the playfield.  Unlike the first Q*Bert, the label is 
    designed to be read while inserted into the ColecoVision on the 
    correct side.  (Q*Bert's Qubes & Mr. Do!'s Castle are the only two
    Parker Brothers releases with this style of label design. - JH) - 24

    If you'd like to try the arcade version, there was one up and running
    at HersheyPark (Hershey, PA) as of 1994.  The ColecoVision version is
    a wonderful port. - JH

Quest for Quintana Roo -

    got to time his jump, and allow him to free fall as long as you dare.  
    Then, pull his rip cord, and get him to land exactly on one of the 
    targets.  But watch out - the sky is full of dangerous helicopters.

    the snow covered slopes, nogotiating the sharp curves with precision 
    and avoiding the treacherous moguls, trees, and other obstacles.  His 
    goal is to traverse the course and reach the finish in record time!

Skiing (Telegames) -

    Telegames Skiing does not have the same graphics as the Coleco
    Skiing which was in the introductory catalog.  Whereas Coleco's
    catalog showed a 1st-person perspective, Telegames' Skiing
    is more like Activision Skiing for the Atari 2600. - 08

Slither -

    Based upon the arcade game by Century II. - 24

Smurf Play and Learn -

    From the catalog: - 24

    Smurf Play and Learn Cartridge by Peyo (Smurf (TM) Peyo (C) 1982)
    Play & Learn Cartridge
    #2444

    This educational cartridge with Smurf (TM) characters bring basic
    learning concepts to the screen and encourages children to solve the
    problems and situations.  Their zany antics make learning fun!    

Smurf Rescue in Gargamel's Castle -

    At the last screen with the skull and Smurfette, leave the room and
    Smurfette will drop her dress. - JC

    If you come up to a hard screen, go back to the screen you just came
    through, and then return - the screen will change shape each time, so
    you can do it until an easier one appears. - JC

    On game 4, move back and forth between screens 1 & 2 for about a minute,
    and you'll receive 919,500 points. - JC

Space Fury -

    Save the best dock for last, since you'll be stuck with it for the
    rest of the game. - JC

Space Panic -

    The stupidest game I have ever played, IMHO.  Why would you want to 
    dig holes, let a monster fall in, and they fall down a level and die?  
    Stupid!  Based upon the arcade game by Universal. - 24

Spectar -

    From the catalog: - 24

    Spectar (TM) by Exidy (Original game copyright is (C) 1980)
    Arcade Game Cartridge
    #2421

    You must direct an armoured car through a tangled maze - negotiating
    sharp turns at high speeds.  But as you traverse the terrain, a variety
    of tank-like vehicles emerge to attack and destroy your car.

Spy Hunter -

    At the fork in the road, the left path give's you the oil supply
    truck, and the right gives you the missiles.  You can use the supply
    truck as a weapon by not entering it and moving it back and forth so
    it collides with your enemies.  When in the boat, it's safer to stick
    to the right; you don't get attacked as much and that's the side the
    exit is on. - JC

Squish'em featuring Sam - 

    If you like 20th Century Fox's 2600 game "Fast Eddie," you will like 
    Squish'em.  It has similar gameplay plus has, IMHO, the first "sound-
    byte" included in it.  Sam actually talks to you (i.e., "Ouch!" 
    "Wow!").  It's worth the price of admission!  Also of note is the fact 
    the cart has a hanger built into it. - 24

    The following dedication is coded into the ROM for the cart:

    This space dedicated to all those hackers who program in 8K but
    are given 16K and to all accountants who want 15K promos - 8

Star Wars: The Arcade Game -

    Explosion of death star not as impressive as other versions - 01

Subroc -

    Sega could not decide whether to make a submarine or an airplane game.  
    So they compromised.  Based upon the arcade game by Sega. - 24

Super Action Football (CBS) -

    This is equivalent to Coleco's Super Action Soccer. - JH

Super Action Football (Coleco) -

    My copy of the instructions give the part number as 2422 - the
    intended number (per the ColecoVision catalog) for Head to Head
    Football. - JH

Sydney Development -

    While Sydney only released one game on their own (Evolution), they
    were a major player in the ColecoVision arena.  Many, many games
    were created or translated for ColecoVision by Sydney.  Among
    these:

    River Raid
    Keystone Kapers
    B.C.'s Quest for Tires
    B.C.'s Quest for Tires II: Grog's Revenge
    Wiz Math
    The Dam Busters

    The company survived past the video game market crash by switching
    over to the Commodore 64 and IBM PC. - 17

Time Pilot -

    "Handles like its constipated" - 01

    Different feel using the ColecoVision controller than the arcade game, 
    which was put out by Konami. - 24

    The Roller Controller works much better; with it, Time Pilot has 
    the feel of the original. - 20

    Tips from ColecoVision Experience magazine:

    As each round opens, your ship approaches the first asteroid, 
    which is topped by a high wall.  To avoid crashing into the wall, 
    use your laser cannon to confirm your flight path.  Since the 
    laser cannon fires straight ahead, the position where your shots 
    detonate indicates the path of your ship.  If your opening shots 
    strike the wall, move until they pass through the center area of 
    the wall's opening.  This will ensure that you enter the asteroid 
    safely.

    As you fly along the surface of the asteroid, stay low enough (about 
    the first mark on the altimeter scale at left) to hit the turrets 
    and tanks on the asteroid surface.  Keep to the left as much as 
    possible, destroying enemy turrets first, and fuel tanks after 
    you've eliminated the turrets that defend them.  The turrets fire 
    both forward and sideways, and theirmissiles move rapidly, so 
    you'll almost certainly be hit if you get close to a turret without 
    destroying it.  Fire at the turrets from a distance, then weave back 
    to the right to hit fuel tanks.  Remember to keep an eye out for the 
    vertically rising missiles that come out of the ground silos - and 
    don't forget the equally deadly missiles launched from the turrets.
    Don't climb unless necessary to avoid a missile or a wall - even two
    seconds at high altitude will bring a fast, hard-to-avoid homing 
    missile down on you.

    As you leave the first asteroid to enter deep space, move toward the
    center of the screen to give yourself maximum maneuverability.  Then 
    wait for the first of the enemy fighters.  You'll find that they're 
    very hard to hit until they approach and prepare to launch their 
    missiles.  The best technique for survival in deep space is  1. Wait 
    until crosshairs appear in front of your ship.  2. Fire instantly.  
    3. Dive or climb immediately.  Don't fire and remain still - even if 
    you hit the enemy fighter its missile will still destroy you.  
    Practice this wait-fire-move sequence until you can confidently 
    destroy the enemy fighters.  By the way, it can't hurt to start 
    firing at enemy fighters as soon as they appear on the edge of the
    screen.  Unfortunately, long distance hits are hard to come by.

    The action will abruptly slow as you approach the mighty ZAXXON.  Move
    your ship to the right to draw ZAXXON over toward that side of the 
    asteroid so you can fire at it.  Then rise to an altitude of about 
    2 1/2 marks on the screen altimeter, and begin firing as rapidly as 
    possible.  When ZAXXON launches a homing missile, try to hit it 
    several times to neutralize it (you'll see it change color), then 
    continue to fire at ZAXXON itself.  Remember, only multiple hits at 
    the right height can destroy ZAXXON - and earn you points.  If you 
    can't score these hits and destroy the homing missile, your fire 
    will at least drive ZAXXON back and you can begin another round of 
    attack. - 35

4.5) ColecoVision and ColecoVision/ADAM catalogs

    Unlike Atari and Mattel, Coleco didn't put out catalogs regularly.
    The catalog was included with the unit is better known for the titles
    that _didn't_ turn up than those that did.  A second catalog with a
    mixture of ColecoVision and ADAM items appears to have been released
    shortly before the death of both systems, as it appears to include
    nearly all of the late ColecoVision releases.  The contents of each 
    catalog:

4.6) The BEST cartridges

    Just what the best cartridges for any system are is largely a
    matter of taste.  One person's favorite is often another's dust
    collector.  However, the following cartridges have all been rated

	Artillery Duel
	B.C.'s Quest for Tires
	Beamrider
	Burgertime
	Centipede
	Donkey Kong Junior
	Fortune Builder

5.1) Instructions

    James Carter has put together a repository of ColecoVision 
    instructions.  These include the text of the instructions only, 
    and are in a text file format.  They are available at no cost;
    however, it is asked that if you have any instructions which
    are not currently available, that you either enter them yourself
    or make them available for James to scan.

    The instructions are available via WWW at Greg Chance's History

5.2.1) ColecoVision Experience

Of particular note among ColecoVision literature is the ColecoVision
Experience magazine, brought out by Coleco.  Three issues came out,
containing ColecoVision news, new products, best seller lists, high
scores, strategy tips, and articles about such subjects as the ADAM
computer, the making of War Games, and intervies with game designers. - 35

5.4) Coleco FTP Site

    An FTP site has been created for Coleco stuff.  The addresses:

    For downloads:  altair.komkon.com  /pub/Coleco
    For uploads:    altair.komkon.com  /incoming/Coleco

    Items at the site include the ColEm ColecoVision emulator, 
    documentation, and ROM images. - 47


6.0) Stickers

When the ColecoVision arrived, part of the hype was sets of puffy stickers.
One sheet contained stickers for Mr. Turtle, Head-To-Head Football,
Mouse Trap, and Rip Cord; another contained Head-To-Head Baseball,
Spectar, Side Trak, and Venture.  Each had a screen shot.
 
Some notes of interest:
 
o Spectar and Rip Cord are the same pictures as the ColecoVision box.
 
o Head-To-Head Baseball, other than the diamond itself, doesn't share the
   same graphics as Super Action Baseball.
 
o Side Trak looks an awful lot like Pepper II.  Instead of a man running
   around the track, a track cart is running on the tracks trying to pick
   up little men. - 24

7.3) ColecoVision BIOS Details

The ColecoVision contains a ROM which essentially acts as a BIOS for the
system.  Upon startup, it begins to execute code at 0000H.  The first step
executed is a check to see if a cart is plugged in.  This is performed by
checking two locations in the cart's memory - if the two bytes read are 
55H and AAH then the ColecoVision knows a cart is in the system.  Otherwise,
it displays the standard "Turn Power Off Before..." screen.

If a cart is in the system, the BIOS passes control to the cart.  The cart
can then use some, all, or none the functions found in the BIOS.  Some of
the functions provided in the BIOS include the title screen and game select
screen.

The famous twelve second delay is part of the title screen routine. - 8

The address range for cartridges is 8000H to FFFFH, a total of 32K. - 29, 31

7.4) ColecoVision Video RAM Details

The video RAM is broken up into tables which are user movable.
The tables which exist include:

The Name Table (this tells us what is in the background)
The Pattern Table (this tells us how each 8x8 character looks)
The Color Table (this tells us what colors to use for a given 8x8 pattern)
The Sprite Table (this tells us where sprites are, what they will look like,
                  their color, and how many to display)
The Sprite Pattern Table (this defines the 8x8 or 16x16 pattern for a sprite)

Four video modes exist:

        A text 40x24 mode.

        A multi-color mode w/ sprites (multi-color breaks the backgroun into
        4x4 squares of 1 color per square. Smurf Paint 'n Play uses this mode.)

        Graphics 1 mode w/ sprites (32x24 8x8 character background. Each
        character is made up of 1 color only.)

        Graphics 2 mode w/ sprites (same as Graphics 1 mode except each
        character can have different colors for each of it's 8 rows.)

The Video RAM is accessable _only_ through the I/O ports, which is why
scrolling is difficult. - 8, 39

8.0) Separate Audio/Video Hack				by Sean Kelly

(The following is a modification which can be used to improve your
 ColecoVision.  The authors of this list and this modification can not
 be responsible for any damage done to your unit or person as a result
 of attempting this modification.)

This is a rather feeble attempt at describing the hack to the ColecoVision
video game system to give separate audio and video outputs to the system.
I am what I call an "Electronics Tinkerer" meaning I have no formal
education in electronics and basically only know what I have been able to
figure out by ripping apart everything I own !

I am a collector of Classic video games and systems and ran across this
hack on one of the many ColecoVision systems I own.  It actually works
quite well and gives the on-screen images a much crisper look to them.
Audio is generally pretty poor on the ColecoVision and this hack doesn't
do much to help it.

In order to get things started you have to open up the ColecoVision by
removing the 8 screws on the bottom of the case.  With the screws removed,
the case is still something of a pain to open because of the lip on the
expansion port, but just keep working at it and it will eventually come
apart.  Next thing is to remove the screws holding down the motherboard
itself (three of them I believe) and take the motherboard out of the case.
On some versions of the ColecoVision the aluminum cover is soldered to
the circuit board.  If this is the case on yours, you will have to desolder
it and remove both the top and bottom parts to the aluminum cover.  Set
everything but the motherboard aside and you are ready to get to work.

The person that did the hack on this system uses a small automotive-type
fuse block terminal to mount the components of the circuit board on.  I
have located it in the 1992 Radio Shack catalog (page 150) and it is RS
part #274-688.  It comes in a package of four for $1.29.  Here is a list
of the components used: AGAIN - I have no formal electronics education
and don't really know how to read all the weird symbols on the parts.  I
will do my best to describe them (I have also labeled them on the line
below for future reference - take note):

  Transistor - No part # markings at all.  Only thing on it is a white, red,
  (T1)         and green stripe in that order from top to bottom.  I assume
               this tells what kind/type it is?

               POSSIBLE (!) RS Part #276-1617   $1.98 (pkg. of 2)

  Capacitor  - Electrolytic type with  part #N8408 on it.  It also has the
  (C1)         marking "470uf 35v", but the "u" is one of the funny symbols
               that I have no idea what it means.

               RS Part #272-1030    $ .99

  Capacitor  - Ceramic Disc type.  Only marking on it is an underlined "47".
  (C2)

               RS Part #272-121   $ .39 (pkg. of 2)

  Resistor   - I know these are defined by the colored stripes (See - I'm
  (R1)         not a complete idiot!!  haha).  The stripes are: Orange,
               Orange, Brown, and Gold.

  A/V Cable  - One Audio/Video cable with the RCA plugs cut off on one end.

  You will also need about 5 small pieces of wire around 4" long each.

We're looking at a total of about five bucks to do this so for parts that do
not come in packages of two or more, I would suggest buying an extra one,
unless you know what you're doing, in case you screw something up.

The center connector on your terminal will be the ground for all the
components because it is the only terminal that sticks out on both sides
of the block.  The part the extends on the bottom will be used to mount
to terminal to the ColecoVision motherboard.  Directly to the right of
the RF modulator (big silver box on the motherboard) right under the
letter of the revision of the motherboard (the one I am looking at is
"J") you will have to scrape off a section of the green coating so you
can solder the terminal on the bottom to the motherboard.  After
soldering this bend the terminal block so that it is standing straight
up from the motherboard.

Since many of the components will be "tied" together, you might want to
connect them all to the posts first and then solder them later.  The way
I am going to describe how to connect them will (hopefully) make it as
easy as possible to understand.  The following is a listing of each post
numbered from 1-5, left to right, looking at the terminal block from the
back of the motherboard.  Looking at the "back" you will be looking at
the channel 3-4 switch as well as the RCA plug that is used to connect
the ColecoVision to the TV/Game switch now. Here is what goes on each post:

  Post #1 - The LEFT "leg" of the transistor.  I am looking at the
            transistor on the side that is curved - where you can see the
            color bands.

            One of the small pieces of wire goes from this post to the right
            leg of the disc capacitor on the ColecoVision motherboard
            itself marked "C22".

  Post #2 - The CENTER "leg" of the transistor.

            One "leg" from the Disc capacitor.

            One of the small pieces of wire goes from this post to the
            underside of the ColecoVision motherboard.  It will be EXTREMELY
            hard for me to explain where to connect this on the bottom of
            the motherboard since there are no markings on this side.  The
            only way I can describe it is to say that it is being connected
            to one of the components in the RF modulator.  The RF modulator
            is "outlined" in a sense on the bottom of the MB with solder
            because of grounding.  You need to connect it to the pin that
            has the marking "+12" at about 5 O'Clock.  This is the closest
            pin to he "+12" marking.


  Post #3 - This is the GROUND post.  One side of the resistor is connected
            here.

            The two ground wires from the RCA cables must be connected here
            also.  Each Audio/Video wire has two wires inside of it.  In
            general, one is shielded in plastic and the other is not.  The
            unshielded wire is the ground.  Connect the unshielded wire from
            each cable to this post.


  Post #4 - The side of the Electrolytic capacitor (C1) that the arrow
            printed on the capacitor points to.

            This is where I am sort of unable to help you.  The positive
            wire from the Audio or Video wire needs to be connected to this
            post.  Since the RCA ends are cut off the cable I don't know
            which is which.  It should not damage anything by connecting
            them the wrong way, so you will have to take a guess.  One of
            them goes on this post and the other goes on post #5.

  Post #5 - The other of the positive Audio/Video wires gets connected here.

            One of the small pieces of wire goes here.  This one is even
            harder to describe than the one on post 2.  The "outline" in
            solder around where the RF modulator is mounted on the opposite
            side is where you are going to connect this wire.  Looking at
            the bottom of the MB with the expansion port facing you the part
            of the "outline" you need to connect this wire to will be on
            your left.  It's  small section of solder (compared to the
            section on the right) and is about 1.5-2 inches long.  Connect
            this wire anyplace here.

You now have one leg of the transistor (T1), one leg of the resistor (R1),
and one leg of each capacitor just hanging there right?  Connect all of
these together, but do not connect them to any of the posts.  Just sort
of let them hang there.

The person who did this to my system also has one other wire connected
to the bottom of the motherboard, but the other end of it has been cut and
is not connected to anything.  I assume this serves no purpose.


9.0) Copying ColecoVision Cartridges

Some ingenious hackers figured out a way to copy the ADAM Computer's
Super Data Packs to blank cartridges that then can be used on the
ColecoVision.  Most of the ADAM Super Data Packs were duplicates of
ColecoVision Cartridges, but contained an extra screen or other extras
the cartridge version lacked. - JC

FWIW, I've now seen both a Super Donkey Kong and Super Donkey Kong Junior 
cart.  The only extras I saw in Super DK Jr. were music during the level 
selection, and a fourth screen, but Super Donkey Kong adds some end-of-
screen graphics (the carry-away after screen 1 and falling girders after
screen 2) in addition to its fourth screen. - JH

Note that copying cartridges or software is a violation of copyright
law unless permission to do so has been received from the rights holder.

Also note that pirated and reproduction cartridges for ColecoVision do
exist.  Some dealers sell them; some refuse to.  Not surprisingly, pirated 
cartridges are considered to have very little collectible value, so be 
aware that they exist - particularly if you run across demo carts and/or 
extremely rare titles.


10.0) Repair Tips

The following are suggestions for solving problems with your
ColecoVision.  The authors of this list and these tips can not be
responsible for any damage done to your unit or carts as a result
of attempting these fixes.

10.1) To fix a rolling picture/video problems:

The problem is with the power switch.  You'll notice that if you were
to jiggle it a little without turning the system off that it will make
a complete mess of your screen.  What I suggest is that you desolder
the power switch from the circuit board, take the metal cover off of
it and clean all the contacts and re-grease them after cleaning them.
Make sure the metal cover is REALLY TIGHT when you put it back on though.
>From then on if you are very careful when turning the unit on/off it
should work OK for you.

If you still have a problem go to an electronics store... and get a
similar switch and replace it.  Nothing else you can do really. - 05

				- - -

Sorry if this is stating the obvious, but you seem to have a combination
of an intermittent open and a heat sensitive component.

Get a can of "cold spray" made for isolating thermal intermittents:
should be a couple of bucks at a local electronics shop.  If you can
get the box open and get to all the components, it should be fairly
straightforward to figure out which one is the bad guy.

Actually, by your description (starts good, goes bad after 2 minutes,
can be affected mechanically) leans towards a bad solder connection
(or socket it the darn thing has them).  It may be as easy as touching
up a few solder connections. - 06

				- - -

If the video problem is simply vertical lines dragging behind the sprites,
it can sometimes be solved by using a different power supply. - 16

				- - -

A number of problems (warping sprites, lack of audio, lines in sprites,
etc.) can, in many circumstances, be solved simply by assuring a solid
connection between the power supply and unit.  This can require 
hardwiring the power supply to the unit. - 33

				- - -

In some cases, sprite problems can be solved by cleaning the cartridge
in question.  But if the startup screen has letters screwed up, such as 
CKHACK, you probably have a bad DRAM.  U10 is D7 and U17 is D0.  CKHACK 
indicates a bad D2 line, which would be U15.  General directions for 
replacing a bad chip can be found in Section 10.3. - 29
 
10.2) To avoid an automatic level select problem:

One common ColecoVision trouble is that the controller ports break down
easily, causing symptoms such as the ColecoVision thinking the keypad is
constantly being pressed (which can cause the a game to be automatically
started, as the level select is essentially instantaneous).  A frequent
source for this problem is the high sensitivity to static electricity
which the controller port pins exhibit.  To avoid the problem, simply
don't touch the controller port pins unless properly grounded. - 08

10.3) To fix an automatic level select problem:

One possible piece which can be blown by static electricity at the
controller ports (see 10.2) is the SN74LS541N chip, a 3-to-8 decoder.
If this is the chip that's blown, then replacing this chip (a generic
component, available at any good electronics store) can solve the
problem. - 13, 15

Parts:

	A good soldering iron (with a very thin tip)
	Computer solder (thin)
	Solder wick
	Needle nose pliers
	An SN74LS541N chip
	Two 2.2K K27 resistor packets (optional/recommended)

Getting started:

Plug in and turn on the Coleco with a Donkey Kong cart inserted.  When the
game automatically goes into play mode, note if the Mario moves without
touching the joystick.  If so, then the 1st player chip is definitely
damaged.  If a two player game is the one automatically started (which
seems to be the prevalent fail mode) automatic movement of the second
player's Mario likewise indicates that the 2nd player chip is certainly
damaged.  Lack of automatic movement does not rule out the possibility that
either or both chips are damaged; indeed, given the automatic select problem,
it's likely that at least one chip is damaged.  But determining that one
chip is certainly damaged can minimize your work.

Surgery:

1) Turn off and unplug your ColecoVision, removing the cartridge.

2) Make certain that you are properly grounded, if possible.

3) Open the plastic casing for the unit.

4) Remove the metal cover from the board by desoldering it.  It just
   gets in the way so its better to remove it.  It is not essential to
   the working of the game, though it can be resoldered later if desired.

5) the bare board upside down and find the soldering connections for the
   SN74LS541N chip that you wish to replace.

6) Note the orientation of the SN74LS541N you intend to replace, so that
   you can be certain that you provide the same orientation for the
   replacement chip.

7) Take the soldering iron and solder wick.  Place the wick on one of
   the solder connections on the board.  Press the solder iron on the wick.
   The iron will heat up the wick which will heat up the solder.  The
   solder will turn liquid and be absorbed by the wick.  This takes some
   practice before you get the hang of it.

8) Absorb as much of the solder as possible from all of the connections
   to the chip you're removing as possible.

9) Flip the board back over and take the pliers.  This is where you have
   to get tough with your Coleco, and let it know who's boss!  Growl at
   it occasionally to let off steam.  Now, being careful not to
   harm any other components on the board, grip the defective chip with
   the pliers and pull and pry.  It's OK to break the chip because it's
   defective garbage anyway.

*** Note - it's a good idea to wiffle each of the pins to pop them off
    any remaining solder.  In fact, if the chip really is dead, it's
    better to just snip or Dremel all the pins off first, _then_ desolder
    the pins individually. - 29

10) After forcibly removing bits of the defective chip from the board,
    remove any broken pins stuck in the board, extra solder, etc. so that
    the area that was occupied by that chip is clean.  Suck up the solder
    from the pinholes with the wick so that you can see right through the
    board through each pinhole.  Gee, your ColecoVision never looked better!

11) Take the new SN74LS541N chip and gently install it in the board,
    inserting the pins in the pinholes.  Make sure that the chip is
    oriented in the same direction that the original chip was!  Gently
    bend the pins if necessary so that they all go in the holes.  Be
    careful not to press too hard as you might bend some pins that aren't
    properly aligned with their holes.

12) Flip the board over.  Take the solder iron and the computer solder
    and solder each connection carefully.  Isn't this fun?  Don't you
    feel like a computer technician now? :)

13) Optional/recommended: Replace the resistor packets on the port in a
    similar (though much easier) manner.  For these parts, note the DOT
    orientation when replacing.

14) Put the board back in the plastic case to avoid shock.

10.4) To fix a broken roller controller:

When a roller controller will not register movement in one pair of
directions (up-down or right-left), the problem might be with the infrared
motion detectors.  The pair of sensors appropriate to the direction
simply need to be replaced with new off the shelf send and receive sensors.

Jumping and contact problems can usually be traced to the bearings.
Sometimes these problems can be solved by cleaning the bearings; often,
however, the problem can not be solved. - 11, 14

10.5) To fix a poorly responding controller:

A simple cleaning with a can of compressed air and TV tuner cleaner can
greatly improve the responsiveness of the standard controllers.

10.6) To fix a dead cartridge:

Most cartridge problems are a result of bad (or no) contact between the
cartridge and the system.  Cleaning the cartridge and system contacts
with alcohol usually solves the problem.  As a last resort, a pencil
eraser or emery board can be used on the contacts of the cartridge. - JH


11.0) ColecoVision Dealers

ColecoVision cartridges are nearly always cheapest when purchased from a
thrift store or flea market.  For example, I've purchased a great majority
of the carts I own, including a number of difficult to find titles, for
$1 to $5.  However, when you can't find a cartridge, there are a number
of dealers who sell (via mail order) a line of ColecoVision cartridges:

Note: the following are listed alphabetically.  An attempt has been
made to provide basic information about their ColecoVision lines.
Inclusion on this list carries with it no recommendation, either
positive or negative, about the dealer.  Additional dealers who
sell a line of ColecoVision products via mail order will be gladly
added to the list.
