===================================================
What is the real story on power supplies and the MAC+.  We all know Apple
says the power usage on the Mac and Mac+ is the same because of some
CMOS chips used in the Mac+, but does anyone know the real story???

Also, when setting the +5 volts on the Mac, should it be set to 4.85 or 4.9?

I was having problems with the external drive being plugged in with a Micah
AT-20 internal drive connected, check the +5, found it at 4.6, so I set it to
4.9, now my system will not work UNLESS the external drive is connected.  It
is weird that adding power comsumption to a powere supply would change voltages
so much.

Any ideas?
