I am looking for info on a National Semi 4916944-2 memory IC in
a 16-pin 0.3" DIP package. I am assuming that it is some variant
of the 4164, but am not sure.

There's nothing like that in the 1980 IC Master. The ICM has a section on NS 64k
DRAMs but there's nothing close to that in there either. Have you got a date for it?

The closest thing to a date code is B8444. I may also have separate
confirmation that it is a 16k bit part.

I've got several NS databooks but that's not an NS standard number. I'd say
is't someone's stock number.

What's it out of? That doesn't look like a NatSemi number to me. Could it
be a 'house coded' number -- assigned by the company that made the
machine it's put in? HP did that a lot (but their RAMs tend to have
1818-xxxx numbers) as did IBM and Xerox.
