Mouse Pointer Will Not Move


Product: Toaster Flyer Lightwave

Platforms: Amiga

Problem: The system seems to be normal otherwise, but the mouse pointer does not respond; the mouse port seems dead.

1) On Amiga 3000T, 4000, and 4000T models, check to see that the keylock is not in lock position. This disables mouse and keyboard input.

2) On the later model Amiga 2000 systems this is usually due to a blown fuse, F1, on the A2000 motherboard, though the port controller chip is also a possibility; early A2000 revisions did not have the fuse, so the chip is definitely the source of failure. For other models, it may be a similar fuse if such exists, or the port controller chip. Static can blow the fuse or chip, but an attempt to use an incorrectly wired GPI cable on the joystick port is another common cause.

On those models with a fuse, the fuse must be replaced, and is a soldered-in component that looks like a resistor, but is green in color. The component is located right behind the mouse and joystick ports. You will most likely wish to have a service center do the repair.

Depending on the Amiga model, the port controller chip may be either socketed or surface mount. "Paula" is the major chip associated with the mouse/joy ports, but there are driver chips in the circuit as well, which vary depending on the model.

Again, it may be safest to refer to an Amiga service center for diagnostics and repair.
