There were memory mapped devices from which you could almost certainly squeeze some out so 'any' is maybe slightly overstated.

Depends on the system. With only one clock source, and no analog input, everything except for user input and disk access time would be completely deterministic.

Not an Apple II expert, but the original IBM PC used a single 14.318MHz crystal to derive every other clock.

There were analog inputs though -- the joystick ports, which were equipped for pong-style potentiometer paddles.
