Hi, I recently bought what were described as boot ROMs for the Amiga 1000. (They contain the code run at startup to load Kickstart from floppy disk.) At least some A1000s used EPROMs, but these appear to be mask ROMs. They are 28-pin DIP ICs, marked like this: MOS 252179-01 ©1985 CBM 5185 TAIWAN 28005A-0054 MOS 252180-01 ©1985 CBM 5085 TAIWAN 28005A-0055 A couple of questions: - Are these actually A1000 boot ROMs? - Does anyone know the pinout of these chips? I want to dump the data from them, but they must be a different pinout to 2764 EPROMs, since using an EPROM programmer to read them was unsuccessful.
