All, I recently bought some Rockwell NOS parts from UTsource (ebay store, located in China). They had R65C02P4, R65C22P4 and R65C51P4 in stock, 10 pieces for $38.00. I bought 10 of each, or $114 and another $12 international USPS service (US Postal service hand delivered it to me at the front door). It took about 3 weeks to get the package, but properly packed and shipped without any damage. All are in static tubes and certainly appear NOS as the pins are all spread and require you to get them at 90 degrees to the case. Chip markings are:

R65C02P4
11450-13
MEXICO
0327 A42553-3

R65C22P4
11473-12
MEXICO
0719 S11545-3

R65C51P4
11470-14
MEXICO
0815 A37995-3
or
0917 A37895-3

So far, I've used two 65C22 and one 65C02 in an older Vic-20. Also used three 65C51 on my small boards and they work per spec and completely stable at 4MHz.
Overall, not bad for $4.20 each (includes shipping to the US). I'll likely try out the CPU and VIA on my existing boards (currently WDC) but will need to ground pin 1.

Thanks - it helps to report good experiences as well as bad, otherwise we could draw the wrong conclusion.
"I generalized from one datum once, and hoooo boy. I'll never do that again."

Hi Ed,

Yes, figured a good experience is worth posting as well. I have noticed that the leads on the 65C22 chips are very soft, they tend to bend too easily so one needs to be careful when installing. Other than that, seems my oddball problems with NMOS 6551 (older ones from Rockwell, AMI, Syntertek I've had for decades) are cured. I recently completed a new BIOS for the 6551/6522 chips so will setup a couple boards with all Rockwell parts and run them for the next few weeks at 4MHz, see how they fare.

In any case, based on the experience so far, I'd buy from them again. They even sent me a USPS tracking number... all for $12, who knew.

I had good service from UTSource as well, both older and newer parts. Well packaged, good turn around time, and best of all reasonable pricing.

I got the last 50 SRAMs for my modules from UTSource as well, and it was a good experience. I think it was Dajgoro who recommended them to me.

What's an additional VIA among friends, anyhow?

I have had good luck with UTSource as well.

G&C have been great too. Only once there was a minor problem when they sent me a batch of cloned MAX7219 chips. They all worked fine, but after I let them know that they were not genuine chips, they instantly refunded my money.

So yesterday I by pure accident stumbled onto an ebay auction for a Rockwell R65C02P4 DIP, seller is Adeleparts which I have bought from before. They seem to auction some of their parts now and then. It's not that I'm short of 65c02 chips, but anyway.. I hit "bid" last night (was on my tablet, reading news), and today I won, I was the single bidder. $0.99, free shipping. Now I must think up something to use it for.

(What I *really* need to build is a time machine that can send all these parts back to my younger self. Late seventies, say.)

Lemme know when that time machine is up and running so I can buy one from you. Lord knows I could use it.
