I found one computerworld reference to a distributor stocking them, 
MTI.  but no hit on the ones I think they are.

I had a friend who worked at a place with this name in Irvine which did 
tape and disk controller systems for more than just DEC.  He worked @ 
Microdata on some projects I worked on, then went back (79 or 80) and 
stayed there.  He had a stake in the company, but he took contracting 
work like we had @ Microdata to help out.

The ad I saw was 1981 computer world for MTI, with just the company name.
