Welcome, Chris, and thanks for your public spirited gesture!

I'm not sure how best to arrange transferring these parts, and I'm not proposing to put myself in charge. But it might be helpful if you tell us where you're located; also where you're willing to ship, and on what terms.

Since there are a variety of chips involved, it may well be that no single individual has a use for the whole lot. Would you be willing to accommodate multiple inquires, each directed toward a certain specific chip(s)? If that's more effort than you're willing to take, I understand, but please give us an indication about that. Thanks again,

Jeff
ps- To keep this thread uncluttered, folks responding to Chris should perhaps consider doing so by PM.

Here is a list of some of the items I want to dispose of, I'm unsure whether they're worth anything (I'm open to offers) but I'd rather not bin them.

MPS6550
MPS6540 (0190479A) programmed ROM possibly for CBM64 but not sure.
MOS6532
MOS6525 A
MOS6522
MPS6504
They are 40pin plastic devices except for the 6540's (3 are ceramic) & 6504's which are 28pin of course and , the 6550 is an odd one with 22pins.

I hope these items might help people with projects or repairs.

I also have some 8088 co-processor boards that were designed to work with CBM700 or 800's I think and also disk drives and PET/CBM ieee488 cables.

I tried to donate some CBM machines to the National Museum of Computing but could not transport it there.
I may be able to post abroad but will need to check carriage.
I will let you know what else I find.

Anyone interested in any of them then please pm me. I can't promise to respond very quickly but will do my best.
Chris.

Thanks Chris. (So, that's a RAM, ROM, RIOT, CIA, VIA, and MPU. And 8088 boards, drives, cables.)
(Edit: oops, see below, that's a TIA, not a CIA - it's a three-port interface adapter.)

Thanks for the listing of the 6502 family components.
Code:
RAM  : MPS6550
ROM  : MPS6540 (0190479A) programmed ROM possibly for CBM64 but not sure.
RIOT : MOS6532
TIA  : MOS6525 A
VIA  : MOS6522
MPU  : MPS6504
Looked up the MOS6525 part in the 6502.org datasheets repository. Hadn't heard of this part before. Seems to be a very versatile part. Might be a good part to use in a new design that utilizes 6522 / 6520 devices. Doesn't have the timer function, but the interrupt prioritization function might be a useful feature.

I didn't mention quantities. I've got tubes full of these ic's but I haven't counted the quantites in each tube yet.

6550 1 tube
6540 9 tubes
6532 14 tubes
6525 5 tubes
6522 9 tubes
6504 3 tubes

So if anyone has a big project then get in touch.

Chris

I sent you a PM.

I do a lot of old computer and arcade game board repairs. The 6532 can be found in pinball games plus the Atari 2600 / 7800 game consoles plus in Fluke 9xxx series CPU pods so there's a demand for them.

I need a 6532 to restore my old genuine AIM-65.

I also have a few tubes of NMOS 6502 and some non-WDC 65C22 that I will never find use for myself. Even a few non-WDC 6551 with working TX IRQ. Not sure if they are NMOS or CMOS. I'm an invalid and has difficulties to check right now. If there are some interest I will try to do it in a few days.
