If this is one of the older shoeboxes, with the separate SCSI adapter
board, it is probably a 60Mb tape with the Emulex MT02 SCSI adapter.
The MT02 has a DIP switch module with switch 1 nearest the edge of
the board.  The switches are:

	Switch	Setting	Description
	1	off	SCSI target bit 0
	2	off	SCSI target bit 1
	3	on	SCSI target bit 2
	4	off	Not used
	5,6	on,off	Archive Scorpion Drive
	5,6	on,on	Wangtek 5000E Drive
	7	off	Drive type
	8	off	SCSI bus parity check

The general board layout is:
