Yup, 6 of them, I seem to recall. In the type of logic used by the
SS machines, it's the clock that furnishes all of the power for

There are some good SS docs on bitsavers if you're curious about the
machine. In the days of vacuum-tube systems, it was noted for its
reliability. Transistor logic eventually rendered the technology
obsolote.

Isn't there a Univac SS80 in Germany in
private hands? The guy used
to have a web site, but I can't find it. Magnetic core logic, but
the clock driver uses a bunch of 4X150s and ISTR that the printer
uses thyratrons. It was operational.
4X150s as clock drivers?!!
