Apple //c power brick schematics

[Brad Wolfgang <brad_wolfgang.doesnotlikespam@meatbyproduct.yahoo.com>]

I have a //c and no power supply brick to go with it. So I decided to try 
to build one. (What Would Woz Do? :) 
If anyone has/knows where to find schematics, Let me know. I'd sure 
appreciate it. 
Although I admit, at first, I was a little discouraged by the DIN 7. ("Good 
grief, no wonder the it's the size of a cinderblock, all those different 
signals and voltages"). Then I pulled up the specs and found out it only 
uses three pins. (Although, I'm still not sure what the difference between 
the electrical ground and chassis ground is, insofar as tying them together 
to the same output on the brick.) 
Like I said, any help is most welcome.
