TTL came out in the 60's, but at BIG $$$ a chip
they could only afford
it for
things like the space program that put man on the moon or large main
frames.
Yes, pretty expensive. I seem to remember from an 1968-ish catalog,
seeing prices of a dollar or two for basic 7400 series TTL, like a 7410.
The more complex chips (more than a few gates) were three or four dollars
a pop.
