Oh.

I guess I must be thinking of some other system; I remember on
various Multibuss boxen, and some CP/M hard disk systems, there
was a "standard" formatter/controller that had the same
form-factor as the 5.25" HD, even mounting with little standoffs,
and cabled closely to the drive; the other end of the controller I
thought was some 'standard' interface (George Morrow quote on the
tip of my tongue though) and via longer cable went to the buss
adapter that plugged in a slot. Can't recall the manufactuerer of
that 'standard' controller. YOu know how memory goes...
