RAM chip specs: HY51C4256S-10

[Michael]

Looking for specs. on HY51C4256S-10 This is an old DIP RAM chip.
I tried the usual suspects including DataSheetArchive.com but no joy.

If I can't find this particular chip, is there a newer, compatible
chip? I have an old printer that would benefit from a few more megs of
RAM.

Tnx,
Michael

Last week I tossed out a couple AST Ram 3000 cards with a meg of them on
each board. Sorry.

Isn't that the way it always goes? It's happened to me before .... and
the other way around too.

It's nice that you've got a tube of 41256's for trade, but the chip the
OP posted about is "HY51C4256S-10" which is a Hyundai 100ns 256Kx4 fast
page mode DRAM, DIP20 package I believe.

Right you are!
