Of course it has a clock, you can't have digital logic without a clock.
Ah, then I misunderstand. =)
So let me get this straight, PDP-11 gets its timing from a crystal? one of those cute shiny things of xxMhz, except 20 times larger in 1971?
I assumed timing depended on RAM speed alone, not counting electricity speed through many yards of wires. So, about ~1000ns per RAM access, and optionally a bit faster with expensive add-on RAM.
