I WAS going to try to diagram my Kenwood PG-4S programming
cable/circuit,,,, but after I opened up the 26pin connector, I gave up.
The tiny PC board inside had more active components on it than I had
realized.... all tiny surface mount. A small 5V regulator IC, possibly
another IC (only had 5 pins instead of 8), and 4 or 5 transistors, a
diode or two, and a few resistors/caps.

Sorry guys, but I don't have the time at present..
