i seriously doubt that i'll even think about doing that.  can you say
"slow?"  i knew you could.  besides, there isn't enough dual port RAM on
the bridgeboard to hold a VGA screen, and we don't have the register
hardware required for VGA compatibility.  if we had the last two, we
could be doing pseudo VGA emulation on the amiga screen today.
