The original Lisa mice seem to have had an oddball
clip
connector. I've not actually seen one though, as I use a Mac Plus
mouse with mine and my Lisa has the more standard D-sub connector
with the screw stanchions. On one of my tests, I didn't have my
mouse mated squarely and it wouldn't move the cursor up or down on
the screen though it would move it sideways. Tightening the
right-most screw on the connector solved this problem.

I have similar Lisa Mouse problems. The mouse, which previously worked,
moves vertically but not horizontally. When you boot up the machine the
mouse pointer starts out on the far left side of the screen but won't
move to the right.
I have opened the mouse and there is no problem with the rollers, and I
have also traced the wires from the Lisa connector to the 6-pin internal
connector in the mouse and there are no breaks. The IR paths also
appear clear, but who knows.
If you isolate and spin the spoked wheel that should move the mouse
horizontally, the arrow jerks around a bit, but does not move off the
left border. I have tried using a Mac 128K mouse, and can with that I
don't get any movement in either direction.
Any ideas, or do I have a board level problem. (I do have that nasty
battery corrosion condition.)
