That's fascinating, thanks. I'd never heard of it. The Intel 4004 came out in 1971. https://en.wikipedia.org/wiki/Intel_4004 I'd understood that was the first chip that could be considered a 'processor' (though it required some support chips to do anything.) The TI Cal-Tech design was begun in 1965 and they had a working calculator in 1967. I wonder if the chips in that had any kind of code programmability? Guy
