This is almost embarassing....I've got a solid state relay connected to pin 16 of my parallel port. I had this working at one time (one hard drive ago) and am thoroughly lost in the configuration settings to turn the spindle motor (just a plain 117V AC) on with the M03 and off with M05 instructions. No PWM, just on/OFF.
