During the time of the Apollo project, from 1964 to 1969, the fastest computer of the world was CDC 6600, which was made with discrete transistors (and which greatly annoyed IBM, because a much smaller company had been able to make computers faster than theirs; the main designers of CDC 6600 had been Jim Thornton and Seymour Cray, who later became well known for the Cray supercomputers).
Integrated circuits became ubiquitous only during the late sixties.
Yes.

btw this is what IC chips looked like during Apollo

This is how they looked after removing the top of their package, not how they looked inside the computer.
This is how the silicon die looked like, with the ten bonded gold wires that went to the pins of the package.
