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.
Yikes. They don't require _parity_ memory modules. (at least,
_consumer-grade_ Pentium systems. My IBM quad PPro Server is fussier.)
