Convert electrical signal to serial I/O

I have a geiger muller counter that is connected to a measurement
counter but I wish to log all the data continuously on to a
computer. There is some kind electrical output, and I was wondering
if a stamp could be connnected to it and convert the signal to
serial I/O.

    Sure. You need to determine what that output is and let the Stamp
    process it. If it's analog, you'll need an ADC, but that's no problem
    to connect. After you have the data the Stamp can send it serially any
    way you'd like.

    If you know the voltage that it outputs then you can use an A/D
    interfaced to a Stamp, then output Serial data in the format you
    want.

    Understanding the "electrical output" would be the first step, then
    the correlation for the serial output.

    Possibly someone else has a better recommendation or if you could
    describe in more detail what you are doing with the serial output
    this could help....
