m0x Posted August 24, 2008 Share Posted August 24, 2008 Hi, I'm new to the forum. I've had an Atari 2600 forever and just purchased two more with some extras. Admist the games, manuals, et al I found a cartridge with a place for ROM chips and a toggle that switches from 16k to 32k. The ROMs have been tested and work, I was just wondering if anyone had ever seen this one before. I want to find out if it's something rare or just an old pet-project. I appreciate the help!

Mox they look like bootlegs, but might be protos. Nice find! Quote Link to comment Share on other sites More sharing options...
m0x Posted August 24, 2008 Author Share Posted August 24, 2008 Any ideas as to the value? I'm not looking to sell it, but my curiosity is tweaked. I have to look through all the games and books to see if the original owner happened to leave his name anywhere. Quote Link to comment Share on other sites More sharing options...

Nukey Shay Posted August 24, 2008 Share Posted August 24, 2008 Bootleg eproms are not prototypes. There were hundreds of such cartridges made independantly back in the 2600's heyday. This one was probably made much later. Quote Link to comment Share on other sites More sharing options...
Nukey Shay Posted August 24, 2008 Share Posted August 24, 2008 (edited) BTW the eproms marked "32" are of 4k games (except Breakout...which is 2k). Edited August 24, 2008 by Nukey Shay Quote Link to comment Share on other sites More sharing options...
m0x Posted August 24, 2008 Author Share Posted August 24, 2008 Wow, all the answers just bring more questions to mind. Why are they marked 32k if they are only 4? I've not been able to find a cartridge anywhere, proto or eprom, that has a slot to switch-out different ROM chips. I tried searching for both, but to no avail. Anyone know where I can find more info on this particular type of mod? Quote Link to comment Share on other sites More sharing options...
Wickeycolumbus Posted August 25, 2008 Share Posted August 25, 2008 Wow, all the answers just bring more questions to mind. Why are they marked 32k if they are only 4? Eproms are typically measured in Killobits not killobytes, and there are 8 bits in a byte, so 32/8 = 4 killobytes. The 2732 (or 2532) chips are 4k and 2716 (or 2516) are 2k.

m0x Posted August 25, 2008 Author Share Posted August 25, 2008 didn't even think of k representing kilobits, haha, that's silly of me. I've not come across another cartridge like this with different games on different chips and that fit into the cartridge. A guy is now wanting to buy it from me but I wouldn't begin to know what to sell it for if I chose to do so. I appreciate all the info. Any ideas as to what you'd pay for something like this as an Atari collector? I was also wondering which you prefer; the six-switch or four-switch "woody" 2600.

m0x Posted August 25, 2008 Author Share Posted August 25, 2008 BTW the eproms marked "32" are of 4k games (except Breakout...which is 2k). I have a guy wanting to buy the cartridge and ROM chips from me. He said something like 10 dollars and I'm willing to let it go but, as you can tell, I know nothing about it. In your opinion is it worth any high monetary value or should I take the $10 and run? Haha, thanks for the help, I really appreciate it Quote Link to comment Share on other sites More sharing options...

I would say more like the $30 dollar range. Quote Link to comment Share on other sites More sharing options...
