True, also 80, 60 and 50, 55sx used ESDI drives either by pass
through or MCA paddle adapters. In many MCA-based industrial, and
many odd network boxens (those black ones), IBM used ESDI
pass-through adapter w/ drive physically bolted to it. Basically
bolted together MCA hardcard. Also P70 used ESDI via cable to the
planar strictly.

On using non-MCA ESDI drives, Not just for IDE adapters there is
SCSI MCA cards, simply pull ESDI drive along w/ adapter if there.
Then put in SCSI card (IBM or non-IBM scsi MCA card and ascsi drives.
 I have done this in my 70-A w/ ST5660N and MCS700.
