A friend sold a TRS80 -> 488 -> sasi pile that allowed him to hook up 
2.5mb and 5mb drives.

I don't recall his company but he did well enough to bootstrap Peer 
Protocols, which I worked for.  It was a SCSI pioneer company and had 
development tools and the like for target and initiator.

He may have used his Argent company name for those sales.  I know that 
another friend was doing similar with IBM PC to SASI and getting $6000 / 
copy.  Noting that the PC's themselves sold for $6000 at the time.  I 
think my friend was doing well too with his profit on the systems.
