My father works in a Polish institute producing radars since the beginning of '70s, they had lots of Soviet chips (though of course they used Polish CEMI parts wherever they could) and he supplied me with them in the '90s. I never had such problems with them. I specifically remember Soviet EPROMs, they had this strange bulging window protruding 2-3 milimeters above the chip casing. He programmed them for me at the institute, as virtually nobody had programmers back then. They were 27xx-compatible and fit in a standard DIL socket. I will ask him about this pin spacing stuff, maybe he would remember something interesting... Regards, Michau. Message was sent through the cbm-hackers mailing listReceived on 2014-04-23 13:01:00
