Along the same line, does anyone have the specs on the co-ax power plug
itself? diameter (outside & inside) and the polarity? I dont want to fry my
brick through experimentation...
Thanks,
Tom
(determining if there is circuitry involved should have two steps-looking at
the connector to see if there is the usual mechanical switch and then
looking inside to see if anything is connected to the switch contacts.
Standard electronic practice would have the internal batteries disconected
by the switch when the external power supply is plugged in.)
