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.
