Peter Wallace Well, from what I'm currently reading in
"Dealers of Lightning", very
early semiconductor memory was quite a bit less reliable than core,
coupled with miserable yields. Presumably both improved reasonably
quickly. It had the advantage of being smaller, cheaper and faster,
though.
Wasn't the commodity DRAM chip back then a 22-pin 0.400" wide 3-
supply device--2107? I think that almost everyone made them.
Not a nice beast, IIRC, slow and power-hungry, with an inconvenient
+12 chip enable.
