Thanks to John's pointer, I've got a CM153 card, so I might be able to
test my stash of CM100 drives at some point. Now I need to track down
the CM153 driver, and an old enough PC that it's got a chance of
working. Having an ISA slot is necessary but not sufficient; it also
requires a sufficiently slow CPU, and I'm not sure where the cutoff
is. Probably need a 286 or older.

Possibilities:
1) Machine with a 'turbo' switch, running in non-turbo mode?
2) Software "slow down" utility? (I remember these, but can't for the life
of me remember the name of any of them!)
3) Underclock the system board? (I certainly did this on a 486 years ago,
replacing its 33MHz oscillator with a 3.x MHz, with no apparent ill-effects
with regards to stability)
