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.

Much help. Although I'm still not sire what the difference is between
signal ground and shield ground, so far as whether they can be tied to the same output from the brick.

The "signal ground" should be called "power ground".

The "shield ground" is the third wire in the US power receptacle.
It is connected to an earth ground in a properly wired building.

If you don't have an earth ground, then leave that unconnected.
The connection between earth ground and power ground is
made with a network inside the //c.
