Well I wimped out and decided not to cut up my good Sound Blaster Pro set of speakers. Instead I used a set of Altec Lansing amplified
speakers. I cut the end off the input cable (the one that normally plugs into the PC) and soldered both left and right wires together and the grounds
together too. Then I got an old audio type plug and soldered the grounds to the ground on the plug and both left and right speaker wires (the
two I had already soldered together) to the center. Next I used a female audio plug and soldered the ground to ground and the other connector
to the sound input to the RF modulator on my 5200. Man that worked great! I now can adjust the volume, treble and bass from the front
of the speaker!
Flushed with success, I got out my experimenting 1200XL (just a motherboard and bottom RF shield) and made another female connector,
but this time I soldered it to the under side of the board on pin three on the monitor connector. When I cranked up the bass while playing
Defender, it wasn't long before my wife was asking me to turn it down, and she's in the other end of the house. Reminds me of when we
used to yell down the hall to the kids to do the same thing... I think I'm going to make this mod on all my machines. I just need to buy a few
more female audio connectors. I won't even have to make any new opening in any of the machines.
