	Sorry, this part is a 256x4 bit RAM, with an access time around
	500 ns - ain't too fast, by today's standards!

	It's a PROM with a *whole* 512 bytes!

	That's probably what it is.

	I believe it is a part from the 1970's.  There were various
	TTL IC's having part numbers which began with 9 or 9N.
