Amiga 4000T Mouse Troubles

[AppleIIGuy]

So i was installing a HxC Floppy in my A4000T... And the mounting holes seemed a little bigget than the normal mounting hole size.. sooo a screw dropped into the case from the floppy and now my mouse doesn't work (When i move the mouse it doesnt move but it acts like im pressing buttons). Mouse & Joystick have +5 V. Joystick port works fine in Amiga analyzer. I also had to remove my Buddha because It would yellow screen if it is inserted. So I belive the Buddha is goners but I would like to get my mouse back.

So, why you tried to install something on a live system? You're asking for trouble.
Anyway, as a workaround, you could use temporarily a serial mouse until you fix what ever you broke. You'll need a driver in a WB Startup folder and a 9-25 pin converter for your serial port.
I did that on my A3000 when I lost my mouse do to someone damaging one of the ICs.
Looks like mouse movements are controlled by PAULA, maybe you can replace that and see if it works.

The system was off when I installed the SD Floppy. The screw fell out afterwards.

Castellen Mouse buttons do not work when pressed. When you attempt to move the mouse then it acts like i was pressing buttons. I do have +5 volts on the mouse / game port
