I'm working through repairing a Tektronix 31 calculator for my dad (late
father's day gift...). It seems to mostly be working now but all of the
display panels except for two are dead (as I understand is pretty
typical). The display consists of two SP-333s and four SP-332s. I've
found a source for the SP-332s (2digit 7-segment displays) but can't
find much for the SP-333s (3digit 7-segment display).
I asume it's impossible ot make an adapter and fit 3 off 332s in place of
the 2 333s.
Here's the specs:

Found a couple of "request a quote!" type listings on the 'net but
that's about it.
I need two of these beasts to get things visible again...
What technology do these use? Gas discharge? I am thinking alound here,
but if they are gas discharge, could they be re-gassed, for example by
the sort of company that makes neon signs?
