Re: TI-H: Fixing Grant's friend's PC
Maybe I'm just WAY out of the loop... since when is a 486 brand new? We're 2 1/2
generations beyond that already, at least (Pentium, MMX, P][).
As for 72 pin SIMMs, yeah, PC's have used them for a while, but we used 36-bit
memory back then. Macs used 32-bit, and recently, and ONLY recently, did PCs head
in that direction. Those 4 extra bits, for those of you on the list who don't
know and DO care, were parity bits, one for each byte.
Any challengers, I'd like some solid evidence, because all of my sources claim
that parity checking only started to die out around the time of the second
generation Pentiums. If I'm wrong, I'd like to know.
