I believe the boards were all designed as a M8045, which was the parity
model, and the M8044 was on the same artwork, just missing a few bits to
make it parity.

The back of the board says M8045 5013128DP1 32K

All M8044's I've ever seen say M8045 in the etch. The M8044 is the
non-parity
version ("MSV11-Dx"), and the M8045 is the parity version
("MSV11-Ex"), and
for the M8044's, they just left one row of chips out.

These all seem to have vanished from E-Bay at
present.
Paul A has (or used to have) a bunch of them.
