Part 3: Vintage IC Collecting – The How.
In Part 1 of our three part series on IC collecting we discussed why to collect vintage computer chips. For Part 2 we covered what to collect, how to set and keep a focus in your collection. For the final Part we’ll cover some of the ways of how to find and collect the IC’s you want.
Part 1: Why Collect Vintage Chips?
Part 2: What Vintage Chips should I Collect?
Part 3: How do I collect Vintage IC’s?
There are two main parts of the How of IC collecting. Where to I get my chips? and Where do I put them? For most collectors cost is a concern, for the right money you can have most any chip, but since i have yet to find the dollar/Euro/yen tree cost is a factor in acquiring chips. One of the greatest sources of chips is eBay. Several categories in particular are a good source of chips, IC?Processors in the Business/Industrial category, the CPU/Processors and Vintage categories in Computing, and Scrap/Recovered Gold. Of these Scrap Gold can yield some of the most interesting chips. Scrap sellers in general though have no idea about what they are selling (as far as collectibility) but most are happy to work with you. If you win a lot with a nice chip in it, send the seller a note to pack the chips well, and in most cases they will. They are sold as scrap though so keep that in mind if they don’t come in perfect shape. This can be a good chance to learn the art of pin straightening.
If your collection includes chips that are ‘modern’ try to have patience, that $20 Xeon will be $5-6 if you wait a few months. IC’s, and processors specifically, pricing usually works on an inverse bell curve. The bottom of which is the end of any real usability, but still too new, and too common to be seen as rare/collectible. The goal is to catch prices at the bottom of this curve. Some chips will hit bottom much sooner, or much later then others, specifically, the fastest/best processor in a given package/platform, will hold its price much longer then any other. For example a 1GHz Athlon Slot A, that fastest you could get, is still a relatively expensive processor. On the other hand, the slowest processor in a given platform gets cheap fast (like a Slot A Athlon 500).
The CPU-World.com forums are another great source of chips, with members posting things for sale daily. It’s also a great source of information for pricing, and information. There are other forums that deal with Vintage computers, and IC’s that may meet your needs as well. These forums also can be helpful in finding people to assist in buying IC’s from overseas, that otherwise would be difficult to acquire. The CPU Shack offers a service through AVICC (Association of Vintage IC Collectors) to help assist overseas (non-US mainly) collectors purchase chips. You can read more about it on the AVICC FAQ page.
IC Brokers often stock many chips of interest, but also list many they don’t which is highly frustrating. They are also generally not set up to work with collectors, they prefer to sell in qty and selling 1-2 chips isn’t ‘worth their time.’ There are some exceptions, such as Demotronic in Germany, Summit Electronics Corp in Florida and ACP Surplus on eBay and several others that will gladly work with the collecting community. a ‘Group Buy’ amongst collectors can often be arranged to help purchase a large lot of chips, or meet a min order quantity requirement.
Lastly, chips may be found in around your community. Yard Sales, flea markets, and Thrift stores often have old electronics for very inexpensive, or even frere that contain chips you collect. I have found numerous interesting processors in old cable modems, printers, computers, game consoles etc found at sales. Sometimes old processors may even be acquired from computers people throw out, once people know you are looking for old electronics, your porch will soon be full. Pay attention to local universities/companies, which often sell/discard their old equipment, they can be a valuable source of chips. You may even be able to work out a relationship with a local scrapper/recycler for chips. If you acquire chips you don’t collect, that’s ok, you can sell/trade them for ones you do.
As this post got a little longer then I anticipated we’ll cover storage in yet another post…

You’ve got an impressive collection!
I really enjoy reading your posts, especially those about ’80s and ’90s RISC CPUs. Too bad the modern age is dominated by only a couple archs.
Keep up the good work.

How old do processors have to be before you can start collecting? What about stuff from the last 10-15 years like P4, older Xeons, etc? Also, what about collecting only the NEWEST? That might be fun, like skylake xeon e7 etc
March 30th, 2016 at 9:32 pm
There is no limit to how old or how new really, other then financial. I collect as much ‘new’ stuff as I can when it hits the bottom of the ‘usable’ curve, ie: as inexpensive as it is going to get for general use. Wait too long and its value begins to rise again due to scarcity and wider collectibility. Collecting newer processors like Skylake is certainly doable, just not easy financially unless you have have a connection (perhaps from some company on a short upgrade cycle)

That makes sense. What about somewhat newer procs that were generally perceived as failures such as itanium? Looks like kittson will be their last hurrah, and in my experience no one had much of anything good to say about itanium. Does that mean it will be of more value or less value to collectors?
March 30th, 2016 at 10:20 pm
Yup, Itanium is a great example, and I enjoy collecting them, they sell for cheap within a few short years of being new, because no one wants them

I have quite a few vintage ic chips that I’m interested in selling just don’t know where to start could really use some help
Thank you

I have a TI SN502 that was given to my father by Jack Kilby. It’s extremely rare, from what I’m told. I can send a photo if you would like to see it.

That would indeed be cool to see

I’ve ran across and bought a truck load of old computer boards, separate chips, and bags of the gold plated things that you make special chips with, 100’s of Computer boards and even towers that are loaded with said boards. I seen one of my boards made by rosemount on eBay for $800. I’ve got over 100 of that particular board. This man was a scientist, pilot, pilot trainer, worked for nasa,etc… I could go on.
I need a place to send some of y’all/admin pics. I know this stuff is expensive, rare, and several of these chips I have that have never been used look like one I seen online that they made jewelry from. It’s obvious that they are gold and gold plated. I’m sure this stuff is worth more money to a collector that being recycled for the gold and other precious metals. Some of these boards are still in the static plastic bag things and have never been used. Some one please email me and let me send you pics. Some of the boards and chips go back to the early 70’s. I’ve learned that much. I even have an original Mac 1. First one Apple made. I’ve heard it’s very expensive and rare. I need some direction as I don’t want to keep these things.
Somebody is going to really freak out when they see what I have. Contact me ASAP and I’ll start sending pic!

My email is bt89162@gmail.com
I’m the man who just posted about the “truck load” of boards and chips. Not to mention the equipment…. most of it has never been used.
Feel free to everyone to email me and I’ll send you pics. I was thinking about recycling everything until I seen what it is really worth. I’m not trying to get rich from this…. and I know I could.
This is a very rare find that all still works. It’s been in his shop.
I bought everything.
I want to get rid of it and give some people a great price. I know this stuff is rare.

Hey can I send you some pics. I’ve got some beautiful CPUs, but there’s no name on them. One is microscopic… if there are any marketing’s, you can’t see it with the naked eye.
I’m also waiting on you to release my questions and comments.
I need help! I’ve got a lot!

I have a huge container with over two thousand motherboards and drives and such. I bet I have 3,000,000 ic chips. Stuff from 70s up
