The software just runs on an Arduino (or maybe Wemos) and you attach a probe to
the pin on the Arduino. There is no PCB involved, but as I said, the results
aren’t great.

Hey Paul, do you have a PCB for what you made for your counter? I'll buy
and we can save the counter from "Nixie Harvesting" ;)

I just attached the probe from the counter to the pin I was toggling. I’m not
sure how your unit would work.

Hi Paul,
This instrument is an odd counter and programmable timer. If you look
close you’ll need the dials yo pick your time interval. I am not a
programmer at all. I did in college but that was long ago.
If I were to modify it wouldn’t I have to cut circuitry? There’s a pic of
the TTL in
I spent a little time developing a frequency generator yo display the time on
frequency counters. Here’s a link to my write up:

Ultimately, not something I’d recommend, but fun anyway.

Look at the pinout. Very odd. And, they were made in Geneva, IL!

The tubes are National Instruments NL-842. They site nicely behind a clean
red bezel.

Yeah you could drive the counter with a frequency generator circuit or
something similar to display time. If it works I would try to preserve the
originality of the whole unit!
Showing time could readily be accomplished with an ESP, Arduino, or similar
for 10 bucks in hardware.
What tube type
Maybe turn it into a clock as is?? Ala Paul Parry

I found this in a surplus store in Los Angeles. Berkely 6401 Programmable
Counter Timer. Built in about 74-75. Completely designed with TTL all in
sockets too.
That's 9 perfect 0.75" tall Nixies and 1 special symbol Nix. Works too! I
can't bare to take it apart to make just to make two
