Hummm...

Dear Dr B.

The question mark after the word driver was meant to indicate some doubt as to whether or not this file is the driver in question. The file, of course, may have nothing to do with the AST Mac86.

When I have a interesting hardware device that lacks only the driver software I check out everything that looks even close. Most of the time it turns out to be just as useless as you predict but sometimes...

Cheers
