Only a couple of tubes - mainly for the power supply. It is a decimal
machine and uses dekatrons.
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.
If anything, the Univac Solid States are more unusual than vacuum-
tube logic machines.
