Anyone know what a Intel P51018SL-10 (32 pin DIP) is?

I have 3 that came with a batch of other IC's.

I think it is Static RAM 256x4 or 1K

That would usually be in a 22 pin package

This is a 128K x 8-bit CMOS Slow Static RAM (100ns).

Thanks Xhoba, that's exactly what they look like. Appreciate the information!

Data seems pretty hard to turn up on this one. I'll test it as a "standard" pinout 128Kx8 sram tonight and see what happens.

If they're more interesting to someone as a "collectable" let me know, otherwise they'll go into a project here.

Funny to think of 100ns as "slow". I still build/repair lots of stuff with 450ns parts Smile

Well, 128K works out nicely for a Z80 and CP/M 3.0 Smile
