Possibly. What's the connection to the drive? If it's 50-pin, in all
likelyhood, it's narrow SCSI.
The rotating selector switch is from 0-F (all single
hex digits, 16 in all,
twice what a Mac has -weird SCSI?).
I've seen external SCSI devices (SCSI ethernet, for example) that used
the second set of numbers to enable termination - 9 = SCSI ID 1 with
termination enabled.
Could this device be what the C Colt can use?
Colts used internal 8-bit IDE drives (X suffix). It has 40 pins, just
like an AT IDE drive, but different at the register level (AT IDE emulates
a WD-1003 controller; I don't know what XT IDE emulates).
You can stick an 8-bit MFM/RLL controller in a Colt and go that route,
too.
