I think it probably would be, except that the two 333's are not actually

on opposite ends of the display, bookending the four 332's :).
They are gas discharge panels. I suppose that might be possible, I wonder
if they would have the right kind of tooling (or if it would be worthwhile
-- would the gas just leak right out again?)
At any rate, I did manage to find a possible replacement (see my reply to
Rick Bensene) and I'll let you guys know how it works...

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?
