Ok, thanks, I'll check into that. Wow, there's a lot of experience out here.
This is off-topic in terms of the industry
involved, but not too
far off in the time period this stuff dates from.
I've got some very nice, rather large Burroughs nixies- 7971 types.
They're 4.8" high, "British flag" display which looks to be 2.5"
high inside the glass. They have 15 segments each-- 14 in the
alphanumeric display part of the tube and one sort-of cursor, an
underline character with the ends bent downwards.
I hear one can dismember D-shell connectors to get some sockets to
solder to a pc board to connect to these. But my problem is driving
them.
For the sockets I'd recommend the Mill-max pin approach; I've used
these for Russian IN-18 and IN-1 tubes in clocks.
Digikey carries a wide selection; see http://dkc3.digikey.com/PDF/
