AMD used 91xx for RAM, 92xx for mask ROM (with a couple of exceptions), and
97xx for EPROM. AM9217 is an NMOS 2048 x 8-bit ROM; A is the speed
(550ns), P means 24-pin plastic, C means commercial temperature range (0-70
Celcius). Pinout is the same as an 8316, 2716 compatible, but the chip
selects on pins 18,20,21 can be specified either active-high or active-low.
The AM9217 was superceded in the late 70's by the AM9218.
Thanks for the info Pete. Too bad AMD didn't put that in their IC website.
