IIGS INTERNAL P.S.: Transplant IIe ps innards

          RESURRECTING A DEAD IIGS INTERNAL POWER SUPPLY WITH THE 
                MECHANISM OF A IIE INTERNAL POWER SUPPLY
          =======================================================


"One small step for an Apple ..... one giant leap for AppleDom!"


Bugg-Power remains the BEST Apple II power supply: abundant power, 
freedom from heat, reliability, low $27 cost.

The ONLY advantage that the internal (standard IIgs or IIe) power supply
has is PORTABILITY --- if you move your computer system frequently, then
the tiny internal unit is more convenient than the external Bugg-Power,
which rests on the floor and connects via a 5 ft cable.

The problem for IIgs users is that the Apple IIgs internal units are in
short supply.  But IIe power supplies are abundant (Crow Fred of
Scottsdale AZ sells IIe power supplies for just $5 each.)

This past weekend, I successfully transplanted a working IIE power supply
mechanism into the CASING of a IIgs internal unit.   IT WORKS!

PROCEDURE:   Open both units.  Remove the six mounting screws, and clip
the wires going to the rocker switch and to the female IEC power socket.
Two of the mounting holes on the IIE mechanism are in the wrong place, so
carefully drill out of the IIE power supply motherboard two holes at the
right places.  (There are no critical traces at those places).  Glue
cardboard insulation along the inner length of the IIgs casing.  Solder
the rocker switch and IEC female power socket to the IIe unit.
Reassemble.   THAT'S IT!

I tested it on a IIgs for a half day before returning the IIgs resurrected
power supply to its local owner.

The only question is whether the IIe unit will generate enough amps to
satisfy the IIgs.   On the +5 and +12v lines, the IIe unit is RATED at
2.5 amps and 1.5 amps, while the printed rating of the IIgs unit is 4.0
amps and 2.5 amps   (By comparison, with BUGG-POWER, you get 15 amps and 5
amps!)

But, with my half-day test, the resurrected IIgs unit got no warmer than a
standard internal IIgs unit, and there were no crashes!

I CAN RESURRECT YOUR DEAD IIGS POWER SUPPLIES in the manner described
here.

COST:  You supply the dead IIgs power supply: I charge $5 for the IIe
unit, $2.00 for labor, plus return postage.

Postage of course is less if you send several units as a batch.

=============================================================
Long live the IIe-to-IIgs internal power supply resurrection!
