[Coco] CoCo 3 power supply

If you do not need the serial port, then you can also bypass the transformer and use a DC 5 Volt 2 amp adapter, because the coco3 actually uses only 5V. But this would also eliminate the serial port in the way it is implemented in the coco3/coco2. The serial circuit is build upon the SALT chip and some converters, and if you use this 5Volt modification then the SALT chip is also bypassed.
