Truly rebooting an Apple IIGS
Miles Attacca
(reset my current BASIC screen, or throw me into the mysterious land of
the Monitor), is there any way to get a full reboot of an Apple IIGS
with another keystroke or a command in BASIC? What information I've
found via Google searches involving keystrokes doesn't seem to apply to
the IIGS.

Ctrl - Open Apple - Reset. Hold Ctrl and Open Apple down while
pressing and releasing Reset. If you are running GSOS, hit the 8 key
while that first screen that tells you the ROM version is up... that'll
make it come up with plain old 8-bit ProDOS instead of GSOS.

Hold down the Command (Open Apple) key while pressing the same keys.

Right, and the important thing here is that Open Apple is being held
down while Reset is *released*. At least on the IIe, I don't own a IIgs.

Each of the three machine designs (IIe, IIc, IIgs) that have this
feature all implement it slightly differently, and are sensitive to
different variations.
The official, sactioned, 'three-finger salute' is to hold down both
control and open apple, then press and release reset. Once you see the
machine rebooting, you can release the modifier keys.

The only time that a //e will look at the modifier key is *after* the
reset ends, which is after either Ctrl or Reset is released.
I would expect this to be true even with keyboard buffering, since a
reset should empty the buffer, too.

Maybe, joystick's first button is stuck being pressed down which it is
linked to Open Apple. Press and hold CTRL key while pressing RESET key
without touching Open Apple before it is rebooting because joystick's first
button is down. Try to disconnect joystick and it should clear Open Apple -
CTRL - RESET to be working fine.

I don't think there was any problem with it not working--just with
what was required.
BTW, if a joystick button is stuck down, pressing the corresponding
Open- or Closed-Apple key will short the +5v supply to ground! Since
this is also true if a joystick button and the corresponding Apple key
are pressed at the same time, that's not a good thing to do. ;-)
(I always wondered why Apple didn't provide a current-limiting resistor
in the Apple key circuits.)

Michael,
No resistor? The Apple Computer, Inc admits to be human error. If no 8
resistors are installed in Apple //e's VIDEO ROM during blanking, it would
screw the screen. Same thing is to screw keyboard.
