I came across a different version that used a 7-segment electroluminescent
display. It was sold for surplus because the display was too dim to read;
those E-L panels were very cool looking, but they didn't last long.
Another oddity on a different model was the case. This device was intended

Boy would I love to have that beauty. I used to have an HP with incandescent
bulbs in the counter modules. They were easy to read from across the room and
simple to replace. It
Yeah

Those are Neon bulbs (NE2A) driven by vacuum tubes (5963).

If you're going with SMD components, you can also try using a SMD crystal
to simplify the build process some more. I used this one for example
(although currently out of stock, but there are probably similar ones)
Hello!
It looks like I was in a Mistake with the datasheet of the crystal,
thinking that the 6.0 to 12.5 pf capacitors would be perfect for the time
running perfect, But with this configuration, I have like 2 mins of delay
in 24H.
I really appreciate the help, Just took a quick look and you are
How I love point to point wiring! PCBs can never replace the beauty of
equipment like that!
