I haven't tried this driver yet. There are 3 *.rbs files on the install floppy. The default.rbs would not copy, so I copied the winword.rbs to default.rbs. I will try getting the file from a computer at work that seems to be able to read files that others can't.
The svmouse.inf file has these lines:
SVMOUSE.Desc="InterAct SV2010/SV2020 Serial Mouse Minidriver"
OSVersion="Win 95 Driver"
