I've got an Amiga external SCSI drive made by
Tecmar that has a 37-pin
connector. Don't have the interface to go with it, though. It's a
modular extruded aluminum case (like some modems) with a 3.5" MFM drive
inside and some flavor of SCSI<->MFM bridge card to do the dirty work.
Mine came from university surplus, so I have never seen it operate, FWIW.
Is this the Tecmar T-disk? I've got a 20meg version and it
requires a sidecar for the A1000, which also provides a 1meg memory
expansion. It has it's own CPU that branches off to both the sidecar
and the disk drive and there are a number of files that have to be
added to the A1000's Workbench disk in order to access it. It won't
boot from the Tecmar.
