Yes.  The Everex The Enhancer EGA card (see my remarks a few days back) 
definitely works with Codeview V1.1 (just shipped by Microsoft to me after
I complained that V1.0 didn't work with EGA and IBM Monochrome Display),
and with the Logitech Mouse, which supposedly emulates a Microsoft Mouse.

The Everex card uses the Chips & Technology chip set.
