 (and friends), MFM/ST506, and SCSI.  But there is a gap of knowledge,
 corresponding with my dim recollection of the '80s, regarding ESDI.
 Are ESDI drives compatible with ST506 controllers?
 Are MFM drives compatible with ESDI controllers?
 I assume the answer to both of the above is no, but I'm looking for
 definitive verification. 
You'd be correct.  They've got different interfaces.  In general, ESDI
drives have a lot higher bit-rate than ST506-interface drives do, as
well.
