	I just remember someone saying that it was possible (on an 3100
30/38/40/48) to use the built-in mono graphics at the same time as the
add-on card... could be bogus... Maybe I'll take the case off and have a

	Those are the GPX boards that support the 1024x864 mode and
	I have a VAXstation 3100 with a SPX card. This is a newer 8 plane
card that supports the 1024x1280 mode. (and the VRT19 and VR320 monitors)
It was used in the VAXstation 3100 (30/40 series) and the VT1300 Xterminal
(which is exactly a 8M VAXstation 3100 with no SCSI daughter card or drive
plate) It was never supported under Ultrix...
