Urg! Thanks for the voltage specs but what about polarity? ;)
Well looking high and low over the adapter. I could not find ANY
markings that would show the tip polarity. it might be on the jack inlet
on the computer itself, which I don't have in front of me. For some
reason I always though the tip polarity was on the inlet itself or was
indicated by the color of the tip (or was that the size indicator?) .
It's too late and past my bedtime for me to give cognizant answers :-)
Looking at the manual though, the battery pack does power the computer
for 6-10 hour normal use. Until you can find an adapter (and the right
tip polarity) you can still power it up by making your own battery pack
as its connected to the computer with a simple 2pin 2 wire connector. If
I can't find the right batteries around the house or shop, I just head
down to batteries etc, and they can always whip something up. Heck they
even put together a real nice authentic looking TOY battery for my vax
with even the plastic coating!! But usually I do it myself.A 9.6 volt @
1.8 A/hr shouldn't be hard to find.
