Hi, I need to get more RAMs for my classic NSC non-parity, but got pretty confused with SIMM naming convention. The FAQ suggests using the following: "1Mx32 One by thirty-two SIMM, Literally Four Megabit Chips arranged to form a 32 bit word. This is four Megabytes (one million base-two 32 bit addresses)". Is it saying that there are 32 1M RAM chips mounted in one module? Does the '32' referer to the 32-bits address? Or 32 of 1 MegaBits Chips? When I open the slab, I saw four out of the eight slots are occupied with SIMM modules; Each of them has 8 chips vertically mounted. So, they are definitely 4 Mega RAM chips which forms 4 Mega Bytes in each module. To be honest, it sounds more like a 4Mx8 SIMM which are used in a MonoSlab to me. There is also 72 Pins on each module which is split into half, 36 in one side, and 36 to the other. BTW, is there any good place (mail order) for SIMMs? Many thanks, g -- +----------------+ | Gary I.
