If any other device uses this connector, it must not exceed these loads by more than 100 milliamps at +12 volts, 200 milliamps at +5 volts, and 10 milliamps at -12 volts, including loads from all other connectors combined." I have a Quantum ProDrive 80S (8 watts) powered from this connector, works like a dream. I did have to re-solder the flyback transformer and connectors on the video/power supply board. This doesn't have anything to do with using the PS to drive the winnie. -- Real life: Thomas Tornblom Email: thomas@uplog.se Snail mail: TeleLOGIC Uppsala AB Phone: +46 18 189406 Box 1218 Fax: +46 18 132039 S - 751 42 Uppsala, Sweden
