I'd assume you've already solved the "problem" as to how to connect VME
peripherals to a QBUS?  I don't see what you are going to do about
that - and whatever device you use to make the connection is going to
affect any "port" of the MaxVideo driver software.

We have a couple of the MaxVideo boards running happily on a Sun3/160 -
it wasn't much hassle at all.  There are two major versions of the
driver software: the old and the new.  The old one simply let the user
map the 4Mb of VME address space that the MaxVideo boards sit on into
a user process.  Then you could do anything you wanted with the boards
by just stuffing bytes, but you couldn't accept interupts (etc) from the
boards.  The new one is a "real" device driver, but we still aren't using
it as of yet.
