As well, some early microprocessors used multiple clocks i.e. the TMS9900.

If you mean 6 different clock sources (i.e.

is not typical of a 1970s minicomputer in my
experience.
IIRC, the KB11 processors used in the DEC 11/45 and 11/70 (and other
related systems) used five "clocks delayed from each other" (more
commonly known as clock phases). In my experience that was more common
in 1970s computers than a single-phase clock.
