Is a Heath H8 classic?
Well, I would think so, but since nobody has given a definition of
'classic', I can't bne sure. Heck, I don't even know if a CDC3300 is
classic.
Before that, there were many. Nixie tube displays were popular on, say,
the CDC 3300.
Obviously you can use 'decimal' nixie tubes to display in octal (just
ingore the 8 and 9 cathodes. Did anyone ever make hexadeximal nixie tubes
with 16 cathodes of the appropriate shapes? I've not seen them in the
databooks.
