Not really, it was Cumana's answer to Solidisk, Acorn and Opus double
density controllers. As I recall it used an odd disc controller chip. I did
have one, but "I had a little trouble Betty", if you do *. or SHIFT+BREAK,
wait for the disc to start accessing and then do CTRL+BREAK the disc is
toasted. It happened once too many times so I removed the board and put it
beyond use...
