Could he run in VCPI mode and make a custom GO32 to map the frame grabber
memory somewhere, just as the first megabyte gets mapped to e0000000? I have
some interest in the problem because I wrote code (in Turbo C) for a Data
Translation frame grabber several years ago, and it would have been much
simpler and faster if the frame grabber memory could be directly accessed.
I hope to use that hardware again someday.
