Greetings, Since completing my K2 in 2002, I've been working on a long term, back burner project to design and implement a nixie tube clock around a Motorola/Freescale HC908. When I finished the clock, I had two unused pins on the HC908 that could be used as a serial interface. I also had room on the board for a TTL/RS-232 converter. In other words, I had the ability to talk to the K2 I/O port.
I just completed "K2" mode for my nixie tube clock. When the clock is powered up, it reads two dip switches and enters 12 hour clock mode, 24 hour clock mode, or "K2" mode. In K2 mode, it sends an "AI1;" command to the K2. The K2 then sends its operating frequency immediately and whenever the frequency changes. The nixie tube clock uses an FSM to parse the "IF" messages sent by the K2, extracts the operating frequency, and displays six digits on the nixie tubes. This feature has no real utility, but it seemed like the geek thing to do. And, it glows!
