Reply to "HELP Seiko S129 / S149 data output jack"

I am interested in the serial cable info and might be interested in making a cable, or two?

Did you know the s 129 and 149 can work with an Alge photocell? Use a thumb switch cord with bannana plugs into the outpit of the photocell and the stopwatch will see the pulse. You will need to power the photocell seperately if they don't have an internal battery.
