There also was a fluorescent screen, maybe for visual
readout or maybe for
secondary emission amplification?
Thanx for the splaining.

ps, Cool idea Allison on a vacuum f. triode flip-flop/ readout.
IT was back if my Valve RF days and someone said they werent real tubes.
later I would use three of them to make a superregen reciever with
audio amplification that ran on a 1.5v and 30V battery. They were
miniature in size ~.350 dia by 1.3 tall and low voltage filiment.
I'd love to find some of the super submini tubes (display or not) again.
