Whats this board?

Ground_Loop:
My old SD nixie counter has numerous SCR-based (actually 4-lead silicon controlled switches) counter cards for each display tube similar to what you've shown.  I'm guessing a counter/driver card.
pepelevamp:
Thats pretty cool. That sounds about right to me. Heh you know, even if thats not what it actually is - the fact that you could probably use the board to control a nixie is enough for me to consider the case closed. I like your signature about not getting old unless ya have stories.
duak:
I count 8 SCRs so I propose a solenoid driver for a paper tape punch. 7 bit ASCII plus parity.  Remex and Facit ring a bell.

These things were also used on CNC machine tools to at least 1984.  In the days before PCs one could edit a CNC program on the built in computer and then punch out a revised version if need be.
