Nope.  The IIgs joystick uses analog inputs to determine the joystick
position.  This power glove appears to use some kind of clocked
digital signal, which is definitely not compatible.

Some more information would be needed on the use of the "clock",
"latch" and "data" lines, particularly the format of data passed over
them, and which device drives each signal.

I expect the clock and latch are outputs from the computer and
data is an input.  If so, it may be possible to interface to the power
glove to the IIgs using the internal 16-pin game connector: you would
have to use two of the annunciator outputs to drive the clock and latch
signals, and one of the switch inputs to read the data signal.

It may be possible to write an Event Manager driver which would allow
the glove to emulate a mouse, but not a joystick.


If the data line is bidirectional, or the clock signal is provided by
the power glove, then you would need some extra interfacing hardware.


How is it connected to a PC?  If it uses the parallel port, then it
should be possible to do this using the Apple II game port.
