LM-512 homebrew Z80 system demoing interrupt system and AY-3-8912 sound

My homebrew Z80 system now has an 8-line prioritised interrupt system (using Z80 interrupt mode 2). In this video, once per second the LM-512 prints the current time (read from the RTC chip) over the serial channel and plays a "ping" sound over a vintage AY-3-8912 sound chip.
