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)
