I found 3 of these a few days ago in a box. Anyone have any idea what they are, what price they go for, or whether they're worth more than scrap?

Those can be some beautiful chip's. Looks like in the 1st picture that the top right corner is chipped, and the bottom edge is chipped. In the 2nd picture there is at least 1 pin missing on the top left side. Any one of these points will send the chip to the scrap bin. There is not a big market for these chip's to begin with. You might get $5.00 for a good one.
Is the top left corner broken, or is the chip shaped that way. I have seen many many many computer components (chips) that had corners that were formed exactly that way, usually just one corner sometimes more. If the corner is chipped, then maybe there is a pin missing, but if not and the chip was made that way, then the pin wouldn't be there obviously. If you look at the top picture, the cut corner looks like it's curved, but in fact it isn't. It's a optical trick created by the opposite curve of the metal grate. I highlighted the area I am talking about. I used a red triangle so I could show the angle of what looked like a chip, it looks very straight. I also rotated the picture, because of the way the brain works, and the way we see things, doing these simple things changes how the brain perceives what the eye is seeing.

I didn't see any missing pins, I don't see a chip on the edge, but I could be totally wrong as it's difficult to tell by the pictures.
To the OP, could you take a better picture, a closeup of the top of the chip, specifically the numbers on the black portion, or maybe type what the model number is? Checking the model number may lead to more information. This is what I commonly do, and it has served me extremely well. ICs I would have normally processed have brought me $35 dollars each just because I took the time to look them up before I processed them.
It's white ceramic, generally speaking they are worth more than the purple or black to collectors as they are older. It could also be Russian, but again I cannot tell because I cannot see the characters that have been written or stamped on the corners, I can make out CCR but not much more than that.
Because they are white, I believe they would be mid 70s to mid 80s. In the pictures the gold looks like heavy gold plating, it has that buttery look, so I have to wonder if it was intended for a military application, or maybe some type of radio device.
This is all guessing. If the chip is whole, and it's not missing any pins, it would be worth far more than $5.00. To the right collector, depending on how rare it is or what it's intended use is, it could either be purchased as a collector item, or even to repair a piece of old electronic equipment. Either could command a far better price than $5.00. If you post more information I'll see if I can't tell you more about it. It's certainly interesting.

Hi Scott,
Thanks for the info. I'll get the numbers tomorrow when I head over to my shop. However, I really don't think the chip is broken in the corner. I noticed that too, and I think it's just shaped that way. I didn't even notice the part number on it. I'll look that up too when I get over there.
Those chip's are made with the corner at an angle. You know I might be wrong. It's an A-1 chip and you should put it on Ebay. Follow Scott's recomendation he will definetly guide you in the right direction on this.
ARISE ZOMBIE THREAD!
ARISE!
Anyway. I bought 50lbs of boards off a guy last year, most of them came from a late 1970's era Burroughs financial computer. I snagged over a dozen of those chips from the lot. They are proprietary logic gates, and the function of each specific IC # have probably been lost to history. They pop up periodically on eBay and IC/CPU collector forums. They have a collector value of $10-$15+ each. As far as I know, nobody has yet wantonly destroyed these rare collectibles to establish a scrap yield and pricing framework :)
Here is a pic of some still on the board that I found via google..

Yup it is a Burroughs chip circa 1970's. Love those things. Have 2 in my collection!
Also have one full board identical to the one Enoch43 posted above on my Burroughs Lamp!
PING POW!

That is too rad! Any other similar geeked out creations?!
Also, found an imgur album I made with some of the Burroughs boards I scored...have a gander......

I got my lamp off Ebay. Some dude got it at an estate sale, had NO idea what it was and listed it as such. Think I paid less than $90 bucks for it and it was hands down one of my best scores EVER on Ebay.
Did you keep any of the boards you snapped pictures of in that imgur album?
LOVE those full sized, gold Proms. SHAWIIING!
I just opened up an old Burroughs computer and found 33 boards but NONE of those, guess I'll have to dig a little deeper!!!Quote:
