Amiga 3000 with jerky mouse and icons switching to monochrome green

Sounds pretty obvious; but it's worth to mention...

Have you thoroughly cleaned the mouse?, do you have any other to test? :-)

As for the A3000, if you don't find yourself comfortable with a soldering iron, simply cut the battery before it leaks. They can do it pretty fast, in less than a year you can get a nice corrosion.
Also, if the mouse itself seems to work fine, the video & movement problems could be related to drying capacitors. If they haven't been changed yet maybe it's time to do it.

So, the most important question now is can I just remove the battery, clean the area (BTW I don't see any signs of leaking yet) without the risk of losing my SCSI settings? I have 2 internal SCSI HDDs and a side car with one more HDD and a CD-ROM reader.

Please advise.

I'm not totally sure about what kind of settings you can loose by cutting the battery but indeed, there're threads like http://www.amiga.org/forums/showthread.php?t=15710 that mostly states the opposite.

In my own experience, some years ago I replaced the battery, the motherboard was cleaned of some severe corrosion, repaired damaged RTC tracks and installed a new battery in a new place...and I didn't have the slightest problem with SCSI, it booted fine back again and didn't noticed data loss. The A3000 back then was a KS1.4 one, maybe the KS has anything to do?
I suppose that if you're going for a clean installation you can be safe about loosing anything, just let HDInstTool do the job :-)
