However, this chip is no longer listed on their website, so it’s probably out of production. They do appear to still make AT28C64, which is an 8k chip. It could be used with 4k games on an 8k board by doubling up the ROM first.

At any rate, another mfr. Posted Sat Jul datasheett, 1: Posted Sat Jul 4, 2: Community Forum Software by IP. Have You Played Atari Today?

Are there any slight or major differences in writing to that chip? Or is it pin-for-pin identical with burning as well as reading?

Nevermind, I found the AT28C64 datasheet. Thanks for the help Edited by Abscissa, Thu Sep 22, 9: Thanks for the help oh here some more pdfs usefull I acctually read a space invaders arcade got chart of a10 and power from some pinball site now onto using two sockets and a to read as a tms futzing w pins you only need a10 and power and chip enable gnded oe g if you want to burn you need voltage on chip enable or select pin up to 25v depending on what pdf says but to read you only need 5v a normal a normal a normal only need 5v pgm and 5v read you need on willem j7 up j5 down!!


I actually booted dataheet using my flashback II cool. You realize this post is 4 years old?

By now, whatever the OP was doing is long since resolved or abandoned. I’ve forgotten my password.
