You could have colored me shocked when I saw the 8080A and its support chips in that catalog! I looked around to make sure I hadn't slipped back 30 years to the Fry's grocery store with the "chips" aisle: potato chips on one side, semiconductors on the other.
What surprised me even more was that while the 8080A was there, the 8085 wasn't.
A Relatively New 8085 IC in a Circuit Built Three Days Ago
Once you add a clock chip and control signal demux chip you're talking real money, especially today when a solid microcontroller comes in at a buck or less.
The real mystery to me is where these chips are being made. Is there some fab out there still cranking out 70's-era NMOS process wafers? On 2 or 3 inch? Or are these old production stockpiles? Or--heavens forbid--did someone bring the 8080A to a new process? Five-metal sub-micron 8080As, still rated for 2MHz, perhaps? I don't think so, but I never expected to walk into a Fry's in 2009 and find 8080As offered for retail sale, either.
I know the 8085 is still very popular in education, is it still in production? If so, I haven't found it. What keeps the 8080A in production? Does NTE have a supplier that keeps 30 year old fab equipment in his basement with a supply of wafers and a packaging setup in the spare bedroom?
Inquiring minds just can't help wondering...
