..i am also looking for info about this card. Have a mach20 with extra RAM, but not the info about the RAM dip-switch settings :confused:
Some info in the WW0340 file (in pdf here) : http://www.gaby.de/ftp/pub/win3x/archive/softlib/1997w3x.pdf

Microsoft advertised the Mach 10 and 20's far and wide back in the day so there must be a few floating around here?

It's amazing how many manuals and drivers have simply disappeared for so many items from the 80's and even 90's.........
