Forgot before, Heathkit used those Sperry/Beckman displays in their 70's-era
digital doodads like clocks, indoor-outdoor thermometers, weather monitors,
tachs, & c., might be a place to look for schematics for examples of real-world use.

Yeah... I read the specs. I'm know about nixies and plain neon tubes,
etc., but I don't know anything about "keep-alive anodes".
There is a vendor and part number etched on the
face: Sperry SP-738.
A little tricky to interface because of the high voltage, keep-alive
anodes, etc. I may have some of the driver chips though if
you're serious.
I would love to make this do something useful. The display was
free (I got it in a pile of parts from a friend who retired and
left the State), but I've always wanted to do something interesting
with it. Perhaps an AVR-controlled, Dallas 1-wire thermometer
display?
