	If anyone is interested, I got two of these scsi serial boxes 
doing nothing on my sparcstation rigt now (they have 4 serial, 1 parallel 
on each box) I bought the machine (the sparc) from the former owner of 
the company that made the boxes (Uninet). He also wrote the interface 
software for the things on the misc. machines they run on (which include 
alphas and DS's) As his company is out of business now, I doubt he is 
afraid of revealing trade secrets, and I can supply you with a email 
adddress to reach him.
