Actually, there are several TMSCP Unibus controllers.
You have the Unibus KLESI, which connects TU81.
TUK50 is the Unibus equivalent of the TQK50.
And then, of course, CMD have made SCSI controllers for the Unibus, which
speaks both MSCP and TMSCP.
And I have a Viking controller which is TMSCP <-> SCSI on the Unibus.
