The other day I requesed help in bringing up some MaxVideo hardware
on a MicroVax.  I guess I should have been more complete in my description
of the situation...
I have a PT-VME903A q22 to vme bus converter from Performance Technologies 
which does mapping of vme devices onto the q bus.  This presents its own
problems since the Datacube stuff COULD use up to 8MB if one bought all
their boards (highly unlikely for us!) and the q-bus is only 22bits wide.
Anyway, the q to vme adaptor does byte swapping on word transfers and all that
for me:  all I have to do is set it up and get it going.  It looks like
quite a bit of work, soooo If anyone out there has any experience with this
device (and especially if you have a spare copy of a driver sitting around!)
I'd sure appreciate any help.

Thanks a zillion,
