Sunol Systems Universal Mass Storage Tape Cartridge Drive SSD-16 T20

The Sunol Systems was open and thoroughly cleaned inside and out.  The unit
powered on and the hard drive spun.  When I inserted a tape disk, the tape disk
spun.  This is as far as I tested this unit.  I am not too familiar with how this all 
works.  It appears to have the software and adapter card (see photos).  I am 
selling this as-is with no returns.   You will receive two tape disk.

The Sunol Universal Mass Storage System is a self contained Winchester hard disk 
storage system which can be attached to a wide variety of micro and mini computers
