Are you talking about FPM (Fast Page Mode) SIMMs?  My understanding was that
these aren't mutually exclusive, I.E., you could have a Parity FPM SIMM, or
a Parity SIMM that isn't FPM.

I'd think that they are parity FPM SIMMs, but since you don't have my ram
tester, and I don't have your RAM, I can't say 100%.  :-)
