hello
in the Cybercircuits demo there is a simple biofeedback monitor
circuit using just the IC 555 connected to the parallel port pins
20,16,11.
it is refering to the software to operate this unit found in the
issue of radio-electronics Oct,1988, there is no archive for this old
issue, does anybody know any information about that.
thanks
George
