[sdiy] Power distribution board

[David G. Dixon]

I've just taken delivery of a Power-One +/-15V, 1.5A power supply, and I
need to etch a distribution board for it.  I would like to build something
like the MOTM board with an array of MTA156 4-pin connectors, and I'm
wondering if anyone can point me to a PCB image for something like that.  If
not, I will have to draw my own, in which case I have a question:

I ascertain that it is important to connect each ground pin to the power
supply ground buss with it's own trace (the so-called "star ground"
configuration).  Is this important enough to justify the inconvenience?  If
so, then should one also do the two power rails this way?  Also, what is the
deal with the two ground pins on the 4-pin connectors?  Are they actually
different?

Power distribution seems like a fairly important thing -- I don't want to
screw it up!
