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.
