I have a Burroughs C3350 and it supplies +200V to the nixie tube

those fingers out of the area of the display.
FWIW it's not that unusual to have HV running around in calculators,
the Panaplex 7-segment displays (which came along after Nixies) also
have about 200V running around inside. You gotta figure if it's
got a neon glow, there's HV inside.

ObCC: I picked
up a Burroughs C3207 calc the other day. Nixie tubes and
transistors. It doesn't go, and I have no idea how to make it go again.
All I know is that Nixies are high-voltage, so I'm reluctant to poke my
fingers in there.
I seem to remember there was a single Nixie tube for sale on Haggle.com...
for around $3.00 or so (at the time...)
Don't they run on 170 volts or somesuch wild figure???
