<By the description, my guess was that pin 9 carries a PWM-signal <(Pulse-width-modulated; a square wavewith varrying block width) to control <brightness. I plan to put a 'scope on it in a working Classic. <In the end it should turn into an analog signal somewhere on the analog <board, I hope. That's what I'm looking for too, so that I can put a <resistor there and bypass the PWM--trouble on pin 9. <I'll keep you posted indeed :) <�mart
Ah, I didn't understand PWM. Yes, if you get the waveform with a 'scope, and you can describe how it changes as the brightness is adjusted, I think I can get someone at work to design circuit to duplicate the signal. If you can't figure out where to put a resistor (potentiometer). In the meantime you could try the LC to Classic with a SE instead of a Classic. This way you could split the PWM and the video in problem and work on the video interface using a SE. Then once you got them both worked out you could merge them back together. johnsn -- Compact Macs is sponsored by <http://lowendmac.com/>.
