Today was much better
Tested with the original driver MOUSE.XR (not yet modified) in BoxSoft compatible mode.
Data bits are not inverted. There was only one mistake in the interrupt service
There are a few trinkets to refine.
The mouse can be disconnected during operation without shutting down the computer.
After reconnecting is ready for operation within approx. 2 seconds
You can also connect another mouse, and its type will be identified (with the wheel or not).
Remained also to do a joystick mode. I still have to think about how he will exactly work, but compared to what already I did this little thing
All the PCBs already assembled. I have yet to mount edge connectors.
I also found and corrected a minor error in the PLD logic.
