Sportybob,
OK, having had a wonderful crash yesterday because a 5/8" drill went 3000 rpm instead of 1500 rpm into the part, I need to figure out this errant speed control situation. You mention the front panel cable assembly.... what do I need there. I did retrofit my machine with a flat panel monitor so we pulled a video cable thru the machine. Can I make some sort of adapter to go from the ribbon cable connector to the red connector? Here are some pictures of what I have, the old panel first (on edit, the pictures switched positions, so captions are opposite):

and then the newer panel, I'll have to track down flat panel for it too... seems to be a larger opening than the last one
