I have an Apple Powerbook 150 PSU. It's 7.5V DC 2A, according to the
seller his 9W PSU is a 7.5V DC 1.2A. So is using the PB 150 PSU gonna
blow my Newton? As far as I can apply my Advanced Level College Physics
it shouldn't, it should only supply what the Newton draws in terms of
current. I thought in my innocence that the Voltage and polarity were
the critical bits and that the current (and subsequently the power)
where dependant on the device. But then I haven't done any electronics
in a while.
The connector is not a major issue, as long as I get the polarity right.
