I've done the basic digging (www.chipdir.com, etc.) and can't find info
on the following chips I found in a box of stuff some one gave me a while
back:
AMD 91L02 - I know it's some kind of SRAM but not the size or pinout. The 9101
is 256x4. This one is likely to be either 1024x1 or 1024x4 but I don't know
which.
NS 74C921 - The 74C922 and 74C923 are somewhat common keyboard encoders, one
of which was used on the Netronics Elf-II design. I can't find any info on
the pinout of the 74C921, but I did find several places selling them from
$6 USD to 72 Danish Kroner (however much that is)
I have a few of each, along with 2Kb of 21L02 chips (-2L and -4L speeds,
whatever they are), all with 1979 - 1983 date codes.
Any clues?
Thanks,
-ethan
