Usenet archives tend to be better when finding out memory chip
capacities IME - luckily the spammers only seem to concentrate on the
web side of things.

Isn't that the other way around? Nearly all PCs I've come across don't
care about parity, but the rest of the world always
seemed to make use
of it.
No, my experience, in the 486 era and earlier, was that on the PC all
the clone motherboards required 9-bit memory. The Macintosh ignored
parity, and I used to know a few Mac enthusiasts who ridiculed the very
idea of parity (spending an extra 1/8 of the price, etc etc)
Pentium and newer systems don't require memory modules.
