I'm STILL confused...does this mean I can use 80ns simms like the ones
I now have in my IIx[from Peripheral Outlet] in a IIfx or are the
simms custom jobbies available ONLY from APPLE? Are "normal" 80ns
simms 64 pinners? I mean how would one specify the correct simms when
ordering from a simm supplier?
