[Coco] modifiying a coco 2 power supply

[Bruce W. Calkins]

Plug 12 volts into the transformer output pins.  IIRC; negative to the 
center and positive to either one of the outside pins.  No other changes to 
the CoCo need to be made.  You will not have negative voltage for the RS-232 
serial port however.  You may or may not remove the transformer, but don't 
plug it into the wall with it unplugged inside the CoCo.  I used a CB 
cigarette lighter power cable with the CoCo end cut in two to fit the CoCo's 
pins.

The coco II  I received is  110V 60Hz

I guess I can disconnect the transformer and
feed a dc signal after the diode bridge ?
