[time-nuts] Looking for a HP-58503 display

[Mark Sims]

The problem isn't a cathode or power supply problem.  It is a phosphor problem.   Selecting a display mode that lights up characters that are not on the default time display shows nice and bright characters there.

The display is a 12 character 14-segment display.   There is a possibility that a HP-34401A display might work.   Those are available from China for around $50.   I'll look at the display when I mount the new power supply.
