Amiga 2000 mouse problem

[drewz21]

I've got an A2000HD that I pulled out to clean up and the mouse ports don't seem to work.  The keyboard works fine and I can control the mouse with the keyboard but neither mouse/joystick port seems to do anything.

Any ideas on what I can try?

Floppy works, hard drive works, and everything else seems to work.

Well crap.  It's got a ver4.4 systemboard in it.  No type of input from the mouse works.

Are we talking total board replacement or is it something that might be repairable?

Thanks in advance!
