Old electronic test equipment in my opinion is very neat to restore and
operate as well.

I have an old HP "event counter" that has 10 rows of neon lamps
representing digits 0 thru 9, that count "upwards" as pulses are presented
on the input to the instrument.

The last calibration was performed in 1963. It is completely made of vacuum
tubes and point-to-point wiring.

I used to work at a military and commercial surplus dealer and all kinds of
neat old test equipment used to pass through. Spectrum analyzers, counters,
and military devices comprised of tube technology were very neat to work with.

Fascinating.
