Just to mention one example, HP`s first CPUs that had hand written timings and other specs used in average hardware. These CPUs were faster than all of these listed, Intel 4004, 4040, 8080 and Motorola 6800, there are more that's just a few to mention. These CPUs were the longest manufactured and so far advanced in every way back than but so rare to find now. Prices ranging from $100 to $5,000 and even $10K depending on which model you have and condition. That's rare

These bring a higher price tag than the lower cache versions of the same cpu so they pass your definitely of 'rare'.

Are they the rarest? Not even close, but they are rare for their generation of processor. I'm still looking for them to upgrade my systems...

Yep, they are a rare bird as you've noticed. And if you come across one, PM me as I'd be interested in it. :)

It's not about you finding them, than mist older items would be rare. It's not black capped either it's just a black pcb no integrated heat spreader. You can but these CPUs pretty much every week out of the year on Ebay or from forums. Not rare whatsoever just collectable. A black on black AMD K6 is really rare. The point I'm making is, you will never come across many CPUs, that doesnt make them rare

Go on Ebay not Rare Birds whatsoever. How much do you wanna spend? I have a couple in my collection I dont need, also a new listed gold recovery lot has 6 or 7 of them just listed today or yesterday. If something is Rare or a rare bird someone doesnt get 10 in one day. Millions of those Pentium Pros were made another reason not so rare

Here's the lot if your interested https://www.ebay.com/itm/Lot-Intel-P...edirect=mobile

Do you guys just do ewaste and scrapping? Just because the model has more cache may net a few extra dollars, they were mass produced and almost every serious collector has every model Pentium Pro besides for models that never made it to market. Those Models fetch premium dollar because not only were they never released they're Sample CPUs which drive the price up higher. Sample CPUs can numerous different types, Mechanical Sample, Engineering Sample, Prototype and some other classifications any sample CPU is highly collectable, not always rare with newer items but everyone in the circles I deal with want them. I've been collecting, learning, studying and a go between in the collectible, rare hardware of computers for 25 plus years.

Are the Non Ceramic Pentium Pro Special, yes, collectible yes, rare no unless you have some Sample of it that makes it Rare, worth a lot more which means people really want it. Sample CPUs really started the CPU collection because in the beginning they were so hard to find. When trying to find those people noticed some models had visible trace lines nick named Zebra Cpus, depending upon brand and model that drives the price up. There are so many different things that aid to the price of a CPU and how collectable or rare it is. And for some people something may be rare to them and that's understandable but that doesnt change anything in the CPU Collection business/hobby. Whatever you want to call it, it gets expensive, to give a example on Ebay a single board with a socket pull c4040 and some other Intel cpus went for $1,250, 500 to 750 was true value but whatever the market is willing to pay changes from day to day

I also think alot of this has to do with location.....I notice sellers in California tend to have huge stockpiles of new old stock vintage Cpu while us hillbillies on the other side of the country just tend to find a few here and there

I agree with that, NOS def can be found on the west coast really good easy. I'm in Virginia and have never found New old Stock. But I do get gold capped and double gold capped everyday usually. I get servers from old contacts when working as a System Administrator VDOT, later moving on to Google, I talked the country and sent broken parts home through the mail.

I also get all the TVs/Monitiors and computers from my local dump. On weekends they serve around 2,000 to 3,500 people. I've lost count how many I've gotten but low c
Balling, 20K CRTs, Computers and servers 7K and that's since 2011. I also get copper pipe, wire and so on. I make a good living without scrap or recovery/refining and selling ewaste on Ebay but it keeps me busy especially since I'm single and no kids. I just wanna retire before 55 or 60.

I have a collection I've started selling off besides for heavily populated pcbs and ceramic CPUs, rare and unique items. Merry Christmas
