TK50-GA external SCSI tape unit + Microvax 3100 Desktop

If the TK50 is terminated and the SCSI IDs are correct (tape drives
historically were ID5) and it's not seen at the console then something's
broken :) There should be a DIL switch on the back of the unit to set the ID
if I'm remembering right, and if you've got a stock MV3100 the internal
disks will probably be ID3 (system disk) and ID0 or 1 (data).
What SCSI cable are you using?
To check that the drive itself is OK you can always take it out of its
expansion box, whip the cover off the VAX and connect directly to the
internal bus next to the 2 disks.
