Looking for the above ICs (or ideas for a source) made by motorola in
the 70's. I don't know much about them except they are TTL chips. Need
only a few (maybe 5 for a few extra if not too expensive) of each- not a
large qty. thanks for any ideas...

My first stop when looking for obsolete stuff. I got hits on the 2023, but
not the 2051.

Probably the 1960's. My oldest books, 1974 list the MC2023 as a
Dual JK flip flop, seperate clock, and the MC2051 as Quad 2 input
Nand. "Consult Factory" for a datasheet...

There are/were a couple of outfits that have real old stuff fabbed up,
or have an archive of dice they package when needed. Rochester Electronics
and Lansdale Semicondutor are a couple of names I remember.
