"spock" = IBM PS/2 Micro Channel SCSI adapter with cache: FRU 85F0063. You can
tell because it has 2 memory dimms (simms) on the board.
I haven't been able to find any information on "tribble". It's
basically the same adapter without the cache.
It was *very* HW specific. The only disk interfaces were the PS/2 ESDI card and
two of the PS/2 SCSI cards ("spock" and "tribble"). I wrote all of
the SCSI subsystem
code.
Hmm... how do I know if I have a spock or tribble board, vs. something else? Do you
happen to know the part numbers?
I hauled a PS/2 65sx out of a dumpster a few weeks ago (using more modern PCs as stepping
stones to reach it) and it's got a SCSI board and a 60MB drive fitted - putting AIX on
it (assuming that AIX is OK with that particular model, and 6MB of RAM is enough) might be
fun.
I can't remember if the 65sx was MCA or ISA. You'll have a problem if it's
ISA.
Currently it halts with 161 & 163 errors, which I think is down to a dead CMOS
battery, but hopefully if I fix that then it will be happy (of course I've no idea yet
what's on the hard disk - assuming that the drive isn't dead - so for all I know
it's got AIX on there already :-)
Probably either Windows or OS/2.
