Apollo’s brain: The computer that guided man to the Moon.

The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft.

What flip-flops were used in the Apollo Computer?

The Apollo computer used few flip-flop registers due to size and weight considerations45, but seven key registers in the computer did use flip-flops: The accumulator, register 00000, referenced as “A”. The lower accumulator, 000001, L”. The return address register, 000002, “Q”. The erasable bank register, 000003, “EB”.

What happened to the AGC in the Apollo program?

The idea of a general computer controlling the mission was abandoned and the AGC was now a specialized machine relegated to backup status. Going forward, ground computers would feed navigation data to the Apollo spacecraft while the onboard computer stood by in case there was a breakdown in the communications link.
