Does anyone have any of these around? I'm breadboarding a project and was tinkering about using this olde, Intel 8255 programable peripheral interface. Or does anyone know who sells these? thanksEd

I think I have a few, condition unknown, from very old motherboards. If you want to buy them, try

-- they may still have them, even if not catalog-listed.
I'll take what you got, if resonable. I'm desoldering some ICs from old mobo's right now, to save some $$.
thanks Ed

Some 8255A essentially compatibles are still produced and are available from Digikey/Farnell/RS Components etc.: CP82C55A, MSM82C55A-2RS, µPD71055C-10, but they are expensive.
These are all alike except that the Harris/Intersil variety (CP82C55A) will hold the I/O ports to a "1" state after reset, which may be sometimes useful and sometimes annoying.

There are a lot of older chips in the lates Jameco catalog that I've got in my mail just yesterday. Almost all of MCS-80/85 is there as well as 6502,
6800 etc. 8255s are in in several flavors and they are not even expensive...

Someone else said Jameco. I gave them a call and now I got some. Now project time. What kind of project can I make w/ this?
thanks Ed
