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.

I finally got my hands on an osiclloscope! 10 CAD at a
garage sale this
week-end. The beast is OLD, but works! I can't find a model number, but
it says "Push pull" and "Extended range" on the front. I bought it
with an
course text book from Institut Teccart Montreal dated 1944 (in French).
Last couple of chapters are about tubes, which is nice because my
knowledge of tubes is limited.
OK, so it's not a computer, but, uh, I'm going to use it to debug
computers! Yeah, that's the ticket. But it doesn't go to very high
frequencies... SO I'm going to use it to debug 9600 baud serial
connections! Yeah, that's the ticket.
