John, how about if . . . oh, never mind.  My understanding of the phrase where
George talks about "256k x 4 drams" was this:  a 256k x 4 dram is a dram with
256k 4 bit wide words.  This used to be a pretty common way to indicate how
wide your memory chips are; has usage changed so much in the last few years?
