[comp.sys.amiga.hardware] More Port 0 weirdness...

mrush@cscihp.ecst.csuchico.edu (Matt "C P." Rush) (11/17/90)

	Well, I ran that Joy Stick test program that Dave Haynie posted a few
days back (thanks Dave!) and got some interesting results:

	When there's a Digital joystick in Port 0, or NOTHING in Port 0, I get
a CONTINUOUS Left signal.

	When the Mouse is plugged into Port 0, the Left signal appears very
intermittantly (as I would expect) when the Mouse is moved.  Those of you who
don't recognize this might want to try using a Mouse on something that expects
a Digital joystick...

	In a nutshell, something is definitely bad in my Port 0, but Port 1 is
OK, and the computer is still functional...

	So my question is:  What is the MOUSE doing that could make that
otherwise continuous Left signal disappear?  And is this information sufficient
to figure out exactly what is fried, or am I really going to have to go to a 
dealer to get a definitive diagnosis?
	Unfortunately, someone is borrowing my hardware manual, so I have to ask
for ALL of this info.    :-(

	Any help is greatly appreciated!
