on a whim I bought
http://www.ebay.com/itm/142363021266
640x480x8 Multibus graphics board with 80286 and NEC 7220
apparently they were commonly used in process control, a fair number turn up at absurd
prices

Seller has another one listed, $60 BIN:

While on the topic of Matrox graphics boards from around the same time
frame, does anyone know of any Matrox boards that use an NS32016 CPU
other than the QG-640?
Someone was asking me about such a board, which is definitely not a
QG-640, with an NS32016 CPU and a Matrox copyright date of 1985 in the
firmware. The board form factor might be something similar to a full
sized ISA bus board, although I can't be sure about that.
I don't see anything in the manuals here that could be a match. The
only one I saw with an NS32016 CPU is the QG-640.

The Matrox PG-640. Same graphics accelerator, but for PC compatibles. I just happened to
have one sitting out on the counter. I checked it and it definitely has an NS32016 on it.
The PG-640 is a dual-width 8-bit ISA card (instead of QBus for the QG-640). It's
supposed to be compatible with the IBM PGC, but presumably only if your software behaves
and doesn't try to program the 8086 on the PGC directly. My experience with the
supposedly-PGC-compatible Vermont Microsystems Image Manager 1024 is that it is compatible
(AutoCAD), except when it isn't (Generic CADD). I haven't actually tried to use
the PG-640 yet so I can't say more about this.
The PG-640 is supposed to be faster than the PGC, too. Perhaps it is, except when it
isn't.
ok
bear.

Thank you. Mystery solved. The board in question does appear to be a
match for the bottom board of the Matrox PG-640 board set shown in the
photos of this eBay listing:

If anyone is interested in images of the Q-Bus version QG-640 I posted
a scan of one here, along with binary images of the firmware:

Back on topic, hope someone can provide Al with a copy of the Matrox
Multibus SX-900 graphics card manual.

Sorry for sidetracking this thread further. I meant to post this link
to the folder, not an individual file.
