In the Commodore schematics each direction seems to have its own resistor, so 4 in total. I've tried to map out the routes on the Microsoft PCB: https://i.imgur. …

It could be dirt, or I also suspect something similar to this is happening: https://m.youtube.com/watch?v=dJgMCd25guY I fixed an old mouse this way. Kept playing with resistor values until I found the magical one that made the mouse smooth again. That's a good reference! It might be related to the …

I've had the same issues with Win95 on my Pentium machine. I had to install my cards in a very specific order or else I would just lose my network card. Windows just couldn't detect it anymore. I suspected it to be an issue with the pnp adress allocation. After MANY hours of trial and error and many …
