UNO does Gas Plasma

Arduino UNO provides 6 bit data and the necessary handshaking logic for a vintage Burroughs SSD0132-0040 Self-Scan gas plasma display c.1976. The row of LED blinky lights, aside from being mesmerizing, shows the state of the interface logic with delays built into the sketch to help diagnostics (on my first attempt I had the 6 data bits in reverse order).
