Correction HP 34702A/34740A. not HP 3470A / 3472A Multimeter dead
 

Hello,

My favorite piece of nostalgia suddenly stopped working. The +5V and other
supplies are ok. The display is blank except for the decimal point. The
culprit is 1820-0798 custom six decade counter. I cannot fin this part but
perhaps one of you has a pinout for it.
