Sorry - More Unknown ][ Cards!

[jdtownend@aol.com]

Hi, may I just pick the brains of any ][ hardware guru's for a moment?

I have three cards that I would like identifying:

"Mountain Computer MULTIFUNCTION (C) 1981" with a 13-pin and 10-pin header
socket.  Multi I/O card?  Anyone have the pin-outs?

"Stellation Two ==/ The Mill (C) 1980" - a really wierd looking card with
a switch on it, hand labelled PACAL / OS9.

"Microsoft (c) 1980" - A small card with some memory chips and a Z80 on
it.

I would really appreciate the advice of anyone who knows their stuff. 
Thanks a lot.
