I am back from my holidays and have been looking at this again. I have realised that the Hybrid Music 2000 MIDI interface is similar, with just three midi outs instead of four.
The addresses are different and the highest one is used for MIDI IN on the 2000 while the lowest is used on the UMI 4M. Another major difference is NMI is used on the UMI 4M while the 2000 only connects to IRQ.
