I seem to remember someone pointing out to me that standard 32mb parity
modules won't work; supposedly DEC had a resistor on the 32mb simms which
allowed the 3000's to figure out which simms are 8 and which are 32...

I've never tried it, though.  I think nmanisca@vt.edu had tried a standard
32mb simm on his new 3000 without luck, so YMMV WTR simms, qed :-)
