What we want to >know is the cost in 1981 of buying a 16K memory chip, without the rest of >the computer. > 1981? I doubt anyone could by "a 16K[byte] memory chip". More likely it was a bank of 8 16k 1-bit chips, or some other combination like four 4k x 4-bit wide chips... I think the memory expansion on my Amiga -- around 1987 -- took 32 or 64 chips to make 2MB; I think they were 256k x 1-bit chips. The expansion chassis cost around $480, and the memory chips were another $400. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
