PCB holding two IN-2B (B-5991) nixie plus two neons for optional colon. Pins for D sub connectors fit well but are realatively expensive except for crimp ones.

New PCB done in 2018 in SVN above with ATTiny861A. Parts kit and PCBs in stock. Designed ATTiny861A which unfortunately doesn't have asynchronous serial either, but at least has 512 bytes of RAM so can be programmed in C. Seems like an ATTiny2313 with serial port could be used too.

9600 * 8 =~ 1MHz / 13 so we could use the 1MHz default oscillator as an 8x baud clock for 9600.
