@kb9ens I don't know the internals of the power supply oscillators. It could be a quartz oscillator, but I wouldn't be surprised if it were just R-C, since the timing isn't particularly important.
As for the computer, it is synchronized to the disk, so its clock comes from a timing track on the disk rather than a quartz oscillator.

@kenshirriff Woah... sounds like that would also be resilient to transient currents and restoration of time after a transient induced shutdown. As ever clever clever...

@kenshirriff @kb9ens that is an interesting combination of design decisions.
The early transistor computer I am most familiar with (Zuse z23) also used bit serial logic, fixed disk (technically a drum) heads and generated its clock signal directly from the rotations of the disk.
It had a core memory register bank though and came quite a few years earlier.
