Thanks Dick, I was going to cut open a 15 pin VGA extension cable and use it. However it has some useful pins missing. Only 9 of the 15 pins are wired in such a cable. Guess I'll have to wire my own.
A word on the band data. They are open collector circuits. They do not supply voltage like a normal LPT port would (e.g. output from most logging programs). One has to wire them to pullup resistors to +5 v to simulate a LPT port. 73 de Brian/K3KO Dick Dievendorff wrote: > > The K3 Owner's manual describes the accessory connector pinout.
