I should mention that this Adic is old enough that it won't fit a FH
5.25" space. It's in its own case with PSU and special front bezel
and is quite a bulky thing. The drive has a small motherboard. One
slot has the motor drive PCB; the other has the tape interface logic.
A ribbon cable connects the drive to a small board in the rear of
the case containing the unit select switches and the interface
connectors as well as a bit of "glue" logic. It's quite an affair.
