Re: Possible MixW ECHO Solution



Radio Shack 26-149A keyboard extension cable shows all 6 pins wired through.
Pin 4 is listed for +5 volts. 13 bucks is pricey, but I want to test this
weekend. I have NOT taken it apart yet to see if, in fact, all pins are
wired through, but that's what it shows in the diagram on back. Six foot
length, male on one end, female the other, listed as shielded.
