Technically IBM calls their proprietary drives "microchannel drives" and they
don't advertise the exact interface type it really uses. The 30-120mb IBM hard
drives (other than SCSI) can be swapped between machine models pretty easily,
generally without even running the reference/setup disk. They mount differently
but have the same interface. I doubt the IBM drives were MFM as the controller
auto senses the cyl/hds/etc without a hitch.
Wanna buy some PS/2's??? I have a bunch, models 30 (8088) through 95XP (8595 not
9595)

30=286 didn't have a cable going to the riser card in it,
nor was it an MCA machine. It was an ISA machine, and The HD plugged into
the motherboard via ribbon cable. I'm not even sure if it was an ESDI
drive. I think it was just an MFM that had everything (including power) on
one cable.
That's right... My memory is fading! Quick, install some more 256k SIMMs!!!
The 30-286 had an ST-125L. A most interesting drive. The 55sx was the one
I'm thinking of, and I think you can swap them to the 50z, too. In the 50z,
the drive slips in behind the floppy drive(s) and plugs directly into an
MCA card. The drives are ESDI. That was something that really suprised me,
not being able to find a power cable. Drove me NUTS. And it shows. When it
comes to PC's, the PS/2 line has to be my favorite. When I'm not cursing
IBM, that is...
