   You may be right, actually. After some digging through the Gravis
web site a bit I finally came across a press release that implies
that the Interwave chip is transparant, allowing for compatability
with the old GUS family. The only exception being that the GUS PnP
uses ROM instead of RAM, so you have to step up to the PnP Pro to
get the 512K of RAM to work with. If true, then it might Just Work,
but I think I'll prepare for the worst...

=>I have no idea if that still holds true for their recent card, however.

   They have docs with the PnP SDK on the web site, but they are
in MS Word format. <grumble>
