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.
