(Scratching head... ) The 41464 are 4bit wide, 64k chips... two provide 64k bytes of
for the Ensoniq sound chip. The other 8 provide 256k bytes of main RAM and are mapped
to 64k banks 00, 01, E0 and E1...
It sounds like you've definitely goy a 256k ROM 0 or ROM 1 GS... I can't tell by the
part # on the ROM. Whaen you power the machine up, does the bottom line on the screen
say ROM 01 or is it blank?
