Most likely. OS/2 would be quite nice, actually; the closest I ever got to
it was using its boot manager circa 1993 to dual-boot a Linux and MS-DOS

I've just hacked away at the Dallas RTC chip and grafted a new battery onto
the top - I'll know in a moment if it works...
thanks,

This one has no cache. IBM FRU 15F6561. It's mentioned here:

it is indeed a tribble board. (Mine has the 64F1368 firmware).

"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? 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.
