I expected lots of people to post the answer to this.  (Maybe they all
sent e-mail to Mr. Chapman, and the answer disappeared down his
mailbox.)  Anyway, Compaq distributes the electronics between their
controller boards and their hard disks in ways that aren't industry
standard.  Your Core drive should work with a non-Compaq EDSI
controller, but not with the Compaq controller.

Needless to say, the MCA controller is useless in an system with AT
compatible (or EISA) (or however that's spelled) expansion slots.

Bottom line:  ask the person who bought the drive.  Or try asking
Core's technical support folks.
