Guys
 
I have a really ancient compaq luggable (I think it was a 286!) power supply that I am thinking of using as a test bench supply,,,the thing has a weird rectangular 6 pin plug with a metal shield. The label on the supply states .....automatic line switching ...input120/240v 60/50hz 1A....max output 18.3V 1.8A.
 
If I measure the Voltage acoss any of the output pins I get around 6 volts over some...1 volt on others about 5 volt on others....measuring against the screen I get damn all useful results.
I am confused how do I figure out what the voltages are? What I would really like is the 18v it states on the supply which I can then regulate to wahtever voltage I need.
 
Any thoughts guys?
 
btw you may have realised my electronics skills are not t hot ;)
 
Cheers
 
Mick
