Question about C/D 500 - 12/07/09 02:39 PM
Hi,
I have a very basic newbie question about the 500 phones. I have several 500s that I have acquired over the years, and I am starting to get them cleaned and working. I have noticed that some of them have cords with four wires red, green, black, yellow, while others have three wires, red, green, and yellow.
Was this a party line thing or simply an economic thing (three wire must be less expensive than four wire)? I know that the early princess phones needed the extra pair for the lighting voltage, but cannot figure this out.
Thanks,
Joe
