I have this Zenith supersport sx laptop (386, black and white screen i think) but no power supply.. The label on teh bottom of the unit states that it wants 16.5 volts, 2 amps... The power connector is one of those small round plugs, and it has a DC noted next to the plug. Does anyone know where I could find a compatible power supply? -Lawrence LeMay lemay(a)cs.umn.edu
