On the topic of unusual devices, does anyone have and spare SED [sound
emiting diode] or DED [dark emitting diode]. There were both advertised in
EDN Magazine a long time ago [mid 1980's if I recall, note sure of the exact
year, but it was probably sometime around April...]
Cant seem to find any current manufacturers....
David.
