[time-nuts] Re: HP5360A

Have 3 that have been working. I say that with caution as they are so old
that they may work or have an issue when turned on. Though honestly they do
tend to actually work.
They are really hard to troubleshoot. One ran me around for months. But did
find the issue. Not that I remember what it was. However each repair is
noted in the manual.
One unit the display had to be replaced so made up a new display with 7 seg
yellow/orange LEDs (Very close to the nixie color)and a micro that did all
of the 1 MHz serial data conversion. It also provides a rs-232 output.
That was a heck of a project.
Totally agree on how heavy they are.
Good luck
