Wow! Thanks for the link. I happen to have a nixie tube strip that looks
just like the one in the AL-1000. The one I have has 12 CD71 tubes (plus
the minus bulb). On the bottom, there are characters in English and Katakana.
Some of the part numbers are "IS-1", "Model 121" and "I2D-E2(B)". The
Katakana appear to be representative of digits.
I've always wanted to do something with this (like so much of my really good
stuff, I've had it since I was a kid). I've just noticed that 12 digits
is enough to make an ISO Date compatible clock/calendar (i.e., 199910220116).
Is there a good reference around about how to drive a multiplexed neon array
going from TTL to 90VAC?
