Atari 2600 ROM part numbers

Recommended Posts

I looked for a list of these and couldn't find one anywhere so I started my own. My incentive for wanting this list was that I have a VCS POP and the games for it are unmarked. This would also aid anyone who came across caseless-games or label-less carts and needed to ID the game without having a way to power up the game to see what it was. Plus, I've found that sometimes powering up a game is not always enough to identify exactly which game it is (Casino or Blackjack, Human Cannonball or Cannon Man?).

 

Without further adieu, here's what I've found so far.

 

co11201 Combat

co11202 Air Sea Battle

co11203 Star Ship

co11205 Outlaw

co11206 Slot Racers

Ah there is some good crossover, thanks! I bet the first three digits on the ROM part number have some special meaning while the last two digits are tied to the title.

Long time between posts...

 

I'm just going to bump this, as there doesn't seem to be any other alternative, but is there a list of part numbers for the ROM chips themselves? The above link is long gone these days, and on archive.org (July 2003 link) it seemed to only be a list of the part numbers you'd find on the labels anyway like CX2601 for Combat. Yes, I know it's a pain to have to desolder the RF shielding just to read them, but here's four random carts to start with (all are in well used/poor condition with the labels already damaged so no value lost opening them). Surprisingly, not even MAME has any info when it comes to documenting the chips.

 

Midnight Magic (PAL version, red label, CX129)

PCB:

C011885 REV G

KALEXCK368 1088

94V-0

ATARI ©1978

 

The 0 in C011885 is slashed on this particular PCB, so it's most likely meant to be a zero and not the letter O.

The 0 in 1088 looks like a back-to-front C.

 

(the 0 is slashed so it's most likely a zero and not the letter O)

 

ROM chip:

C300046-129A

©ATARI 1986

RP2C12 1008

38 8B4 A0

 

Midnight Magic also has 129 stamped in red on the RF shield (obviously the game ID since it matches the label).

 

Plaque Attack (Activision, AX-027)

PCB:

©1980 ACTIVISION

AG-910-02D REV D

 

ROM chip:

33511 8334DPP

AG-027-21

©1978 AMD

©1983 ACTVSN

 

Plaque Attack didn't actually have any RF shielding. Not sure if it's a PAL release (I'm in Australia) or a US import - PAL versions of Activision games usually have the ID as EAX-xxx (E for Europe). The cartridge is dead so I can't test it (I accidentally let out the magic smoke 15 or so years ago when I was testing a faulty 2600, had the cartridge opened for cleaning, put the bare board into the console and forgot that the chip side is supposed to face the back of the console!)

 

Combat (PAL, picture label, CX2601)

PCB:

C010789

ATARI ©78

M

 

ROM chip:

9316B-7A13

C012501A

8217 CEA

© 1978ATARI

 

Asteroids (PAL, picture label, CX2649)

PCB:

C011885 REV F
ATARI © 1978

 

ROM chip:

8151
C49005
C017449A-03
©ATARI1981

RF shield also has 449 printed on it twice as well as E-B stamped into the metal.

You'll find many of the part numbers you're seeking in the Atari EIS item master list, found here. You won't find anything for later releases like Midnight Magic since the document is dated January of 1984, but the master list is a good starting point, anyway.
