 I have a bunch of MS, Mac. Atari, Commodore, Logitec and other
clone mice. They all have either the DB-9,or PS/2 or Mac sub-mini
with keying pin. I seem to remember seeing mice with large round
connectors which I assumed were the same size as K-B ones.
 This has a shell diameter of 1/2". Possibly I'm not acquainted with
 the round bus mice. I'll have to try the card in a ISA box with CGA
and Mono monitors and hope the magic smoke doesn't escape. It's
about the size of a Hercules card with a much smaller chip count.
Might be just the thing for my heavily modified IBM PC to replace
the outsized color and mono video cards.

Thanks All
