IC Collecting 101 New Vintage Mil-Spec Integrated Circuits

The US Military and NASA has produced some of the most spectacular integrated circuits design for harsh and high reliability environments. The recent repair of Hubble and the return of our Astronauts could not happen without the semiconductor industry and the incredible technology inherent to these electronics gems. Here are some that are MIL-SPEC that we placed on eBay as well this week....

Collectible Semiconductors: Transistors Diodes and More!

Old Semiconductors from the !960's and 70's are some of the most prized additions to my IC and Electronics Collection. My wife is getting difficult about bringing more stuff home but it is really fun. Cataloging these old parts is very difficult as some of the logos are hard to identify and many do not have datecodes. Here are some new additions...

RTL CTL CµL LOGIC in the Early IC Technology at Fairchild Semiconductor

Back in the early 60’s Fairchild and Texas Instruments decided to develop new technologies and integrated circuits for the commercial marketplace. For Fairchild the big breakthrough was Planar technology that made them one of the key players in the early days. Initially the first IC’s were RTL (Resistor Transistor Logic) followed by CµLOGIC (Counting Logic). Most of the sales were to defense contractors in fact NASA used the 914 and 923 on the Apollo Guidance Computer. Prices in those days were around $50 each so I decided to offer some of the same types of parts at prices below the threshold set in 1960-70. I actually worked at Fairchild in the early 1970’s and some of these parts were still being sold- although DTL was the hot part when I was there! So here are some of the parts that I have added to eBay and lots more coming…
If you have input on what these parts actually are and what they were used for please send it along. All I know is there were basic gates and flip-flops in those days!
Thanks
Dave

NEW Discovery! Intel Collectible Museum Quality D8748H and D8751H Processors!

A good friend of mine turned me on to a few tubes of "Museum Quality" Intel Processors. The Micro Controllers are already available in used and as pulls but it is rare to add some new in the original tubes to your IC Collection. These were both very popular parts in the early 1980's. Not sure the datecode of these as I still don't know how to decipher all the old Intel lotcodes. Wish some one would help. Just put them up on our eBay website today... Nice parts!
