no, the QDSS (VCB02) was used in the VAXstation-II-GPX.  the monochrome
QVSS (VCB01) was used in the VAXstation-II.  the QDSS was power hungry
(somebody told me it had some ECL on it) and getting it to work in a BA23
was iffy -- DEC only sold it in the BA123.

i don't remember what the VAXstation 2000 used for color graphics -- but
didn't the VS3100 use an MFB or CFB, same as the DS3100?
