BBC MIDI interface

This was inspired in 1989 by a circuit diagram reflected in the glasses of a person on the cover of a computer magazine. I extrapolated the rest of the circuit and built the interface. After several hours trawling through Stirling University library in 1990 I discovered the original schematic in the April 1987 edition of Electronics Today International.
