Gunstar Posted December 3, 2001 Share Posted December 3, 2001 What is the chip that is on the outside of the casing's "firewall" on the pcb? I have Pete Rose and Title match. I was cleaning them out today and noticed these chips that are visible behind the card edge. This isn't a Pokey chip or some extra sound chip is it? The case seems to be identical to the Activision 2600/7800 cases, so I'm assuming that absolute used more chips than Activision and had to put a chip out there to fit it...Do all the Absolute games have this chip?

DanBoris Posted December 4, 2001 Share Posted December 4, 2001 The only Absolute game I have (F18 Hornet) doesn't have this chip. How big is the chip, how many pins can you see? If you see 12 or 14 pins on one side of the chip then it may be an extra ROM or RAM chip. If it has less the 12 it may be a logic chip to control bank switching.

+Mitch Posted December 4, 2001 Share Posted December 4, 2001 All of the Absolute games, except F-18 Hornet, have that chip. It has 14 pins total. But, as these are all 32k games, I doubt it is for bankswitching. I really have no idea what it is for and I don't want to open one to find out.

+Mitch Posted December 4, 2001 Share Posted December 4, 2001 OK, after much straining of eyes looking in the end of the cart, I was able to decipher that it is a 74LS04. Hmm, I wonder if these carts have EPROMs in them. The 7800 Double Dragon that I opened up did. Mitch http://atari7800.atari.org Quote Link to comment Share on other sites More sharing options...

So much for that cartridge lasting 'forever'. I hope not many 7800 cartridges use EPROMs. Any confirmation on a Double Dragon cartridge that doesn't use EPROMs? I hope bit rot doesn't settle in for you :-( Makes me appreciate emulation even more so. Although nothing beats the genuine thing :-) -Trebor Quote Link to comment Share on other sites More sharing options...
+Mitch Posted December 5, 2001 Share Posted December 5, 2001 The Double Dragon that had the EPROM was the PAL Salu/HES version. The Activision version I opened had a standard ROM. Mitch http://atari7800.atari.org Quote Link to comment Share on other sites More sharing options...
