This means that it requires a little setting up and will only work for RC2014s with an SIO2 (and port B not already used). My challenge to myself is to  learn how to connect a serial chip (probably 68B50 ACIA) to receive the incoming MIDI and to serialise outgoing MIDI design the module, including the port decoding write a library so that it can easily be used on any RC2014. Potential applications include a MIDI sequencer and using incoming MIDI to trigger notes on the AY or SID sound chips. Entering the Retro Challenge 2024 (aka RC2024/10)  has given me an incentive to get on with this! I'm happy to see several more entries in the RC2014 category, including another musical project.  Tue 1 Oct  I've ordered a 68B50 aks ACIA. I think it could also correctly be d
