I've just been sent some chips from what I believe was a Commodore repair facility here in the UK. There are some uninteresting production ROMs, some EPROMs and some other chips. There are some EPROMs claiming to be 1571 beta ROMs, Script Plus Hi and Lo EPROMs, a C128 EPROM, a "Tool Kit" EPROM and some less identifiable EPROMs. I'll try to get these dumped ASAP. There's also a 6569R1, another purple ceramic chip with gold pins which I think is an Intel chip and finally three 8563s. The revisions on these look like early production chips (possibly with bugs) so I am listing them in full: MOS 8563R6 4C 1285 MOS 8563R7A 1885 There are two of the latter chip. I've read hacker documentation advising the use of R8 or R9 chips, so does anyone know what the bugs are with these earlier chips? Richard Message was sent through the cbm-hackers mailing list
