[time-nuts] HP 3586 Questions

[Peter Gottlieb]

It was reasonably easy to get to the input connector to replace it. I haven't 
seen the firmware source code but would be interested if it became available to 
play with.  Some HP instruments used proprietary CPUs (or "nanoprocessors") 
which might be tricky to play with due to their instruction set not being published.
