I can report that on the actual m/b, the 4 1Mb 30-pin SIMMs
have 9 boxes on the modules which I believe indicates
parity modules; the 16Mb 72-pin SIMM, however, has 8 boxes
on the module indicating non-parity.  And the manual says
nothing about parity chips being required.

Both parity and non-parity 30-pin and 72-pin FPM SIMMs are available
from:

http://www.memoryx.com/generic.htm

but, as you say, are too pricey for serious consideration.  Short of
getting ahold of a 64Mb 72-pin SIMM and trying it out in the m/b, I
fear I will never get to the bottom of this.

Many thanks in any case to the amiable subscribers of pcbuild for
trying to solve this puzzle.
