[Elecraft] K3 Cabling Questions

[K3KO]

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.
