Did you lose the other one, or is it simply broken ? If you have a multi-meter, you can figure out th pins very easily..... turn on the laser - pick one pin for the positive - and move the other probe around (the negative one) until the laser lights up. If you get to the last pin without it working, then put the negative probe onto the pin you ariginally selected, and move the positive probe around. After you identify them - use that $2.87 SVGA or PS2 (Cannot recall which it is) plug, and identify the pins that need joined together....
Oh yeah, turn the multimeter on to either continuity testing, or DC voltage - at about 10V would be fine. THAT should get you back up and running !
