I haven't found a way to drive nixies from more

not one that I understand, anyhow. Especially the Burroughs 7971
"British Flag" one. I thought of building a character generator using
a PAL, but I really haven't decided what I want to do wit them yet.
Maybe create an "On the air" sign with my callsign, alternating with a
clock display.
Nixie tubes are actually really easy to drive...74141 chips (BCD
input, not for your B7971s without some fancy footwork) are hard to
find, but Russian clones of them (K155ID1) work fine and are readily
available. Lacking that, MPSA42 transistors can drive Nixies. The
only real problem is a source of HV, but several people (including
myself) are working on small "canned" HV generator modules which will
be available cheaply.
