Both mouse ports are partially not working on my Amiga 4000/30. Buttons work (I can right/left click), but not the movement detection.
It's not a mouse problem, the same mouse works on a different Amiga, so it has to be a motherboard problem.
I wonder if there is a way to easily detect where the problem can be, maybe changing / replacing the dedicated I/O IC on the board?
Please help if you can: I need to transfer tons of data to PC and moving the cursor with the keyboard (A-arrows) is not the most comfortable way do work...
Thanks
PS: Hi have 3 more Amigas: a 4000/40 (not starting at all), a 500 w/HD - working perfectly, and a veeeery old (non working) A/1000, from 1985 with a noisy custom made 10MB HD.
