ZM1206 (ZM1206)

This is a project that Dave Bliss, Mike Stapleton and I implemented to demonstrate the functioning of a very unusual and rare Pandicon tube.  The tube has 8 or more nixie displays in the same neon atmosphere thus making driving it complicated.  We used a micro-controller programmed to calculate Pi, "e" and the golden ratio, high voltage opto isolators and three bias voltages to produce a clean image.  The power supply is 200 vdc at 11 ma, and 5 volts.  It was a very fun endeaver and turned out to work very well.
