   I sure hope you now know that a transformer works on AC not DC. And
   putting DC on a transformer could be a shocking experience if you were
   holding the leads when the power is removed (flyback).

     Back in '97 while driving big trucks I pulled the transformer from a
     CoCo 3 and plugged in 12 volts, negative to the center and positive
     to
     one of the outside taps. This did not provide a minus supply for the
     RS-232 serial port, but as I did not run a printer it was no
     hardship.
