Yes, we have several 6300s working with other video cards.  There are
about four jumpers that have to be installed on the AT&T video card to
disable it.  I suggest that you call AT&T support for details, but if
there is sufficient interest I could get the information from our hardware
technician.

We have had no problems running the 6300 was an IBM CGA or with a Hercules
color card (though the parallel port on the Herc card doesn't work).  We
once tried without success to install a Quadram QEGA+, but I am not sure
whether the problem was with the card or the 6300.  (Cause I then tried it
in a vanilla IBM-PC, it didn't work there either)
