So I helped someone move out recently, and they gave me a little organizer that was used for small electronics. It still had hundreds of potentiometers and resistors in it. It also had a curious looking 64 pin integrated circuit with a large heatsink attached to it. I didn't think anything of it and put the organizer with the rest of my electronics goodies.

 

Well today my curiosity got the best of me, so I went out and grabbed the IC with the heatsink on it and removed the heatsink to find a part number and manufacturer on the chip. TRW TDC1010J. 64 gold plated pins in a ceramic package. Did some research on it, turns out to be one of the chips used in original Doppler technology. Used in the Military and in Avionics, an accumulator/multiplier. Interesting, we used some stuff like this in electronics engineering, but the ICs we were using were much smaller. In 1984, CERN used these ICs studying high energy physics.

 

So I am thinking to myself, this chip has an interesting history behind it, so I dig a little deeper to find this exact chip for sale on a server parts site for $450!

 

Even further, they are listed on Ebay for $250-350!

What a freebie! lol.

 

I know we have a couple of crew members who deal with electronics and I was wondering if any of you have heard about/dealt with these chips?

 

Here is an ebay link to an auction for one of these ICs,

I was flabberghasted when I saw the prices on it, I myself havent come across a chip this large as well. Biggest chip I have is the ECU chip I have in the aftermarket ECM I put in my car, and thats half the size as this one. It is a curiously large chip, though it is older tech. It can take 2 16bit values and return them with a 32 bit sum in 255nanoseconds! Thats pretty powerful for what it is. None the less its a nice find, and a piece of electronics history for sure. Though it was hard to come across information on it; in fact most of the info I found was scanned into a computer from actual paperwork.

 

I remember making 7 segment displays run through a random or preprogrammed set of values, even counting above 10 on a single 7seg display and that took 5 ICs if I remember correctly and a crapload of jumper wires, lol. I still use my protoboard on occasion building useful 555 timer circuits, which comes in extremely handy for test building add-on circuits to my ECM in the car. Currently I am running a GM HEI ignition mod to fire spark in my car, also have a circuit to absorb flyback voltage for my intercooler fan relay, and launch control/antilag for building boost without brake boosting. The antilag is awesome when I'm running open downpipe, it shoots flames when its on. I will have to get a video and post it up when I am done tuning.

 

Only downside to the antilag, being its cutting spark I can only use it without the muffler, cause the muffler will turn into a bomb with all the unburnt fuel :/

 

Anyways, I'm going to list it on ebay for about $200, thats cheaper than the rest of the auctions for the same chip and it was free so its all profit if it sells, which I am hoping it will. Much needed gas money for pounding pavement to find some work. And maybe, just maybe some crappy American beer, lol.
