Mystery CPU

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.
