Hi all,
I recently came into possession of two Duo 230s in a lot of six random old Apple laptops. Sadly, these machines were the only ones in the lot without power supplies. I'm obviously going to have to buy a new power supply or two but I was wondering if the supplies from any other PowerBooks were compatible. I have a 1400c supply and the voltage and connectors match but I'm not sure about the connector polarity. I vaguely remember there being some oddness with certain PowerBooks being centre-negative while others were centre-positive... or is the power connector actually tip-sleeve and the metal shield is just structural? I don't know PowerBooks very well outside of the G4 era. Can anyone here confirm that a 1400 supply is safe to use with a Duo 230?
Any tips on compatible third-party power supplies would be well appreciated!
Thanks all.
