[time-nuts] Dumpster diving - found counter!

As I was going to the computer club I saw one of those small containers they
dump things in. As I looked closer I saw it was promessing. As I left I got
some help from a friend and ended up finding a Marconi TF2415 counter/timer.
It happily measures frequency, period or time interval with up to 6 digits.
Good old display valves, including Hz, kHz, MHz, us etc. Obviously needs some
attention, but should be a nice complement to the HP 521C. :-)
It fires up and counts resnoble when fed from my HP 200CD oscillator.

The 7 General Radio 578-A transformers with dual banana-jacks for each port
doesn't hurt either. :-)
