amiga 2000 suddenly dead, what happened?

[dougal]

Well I think I found the problem.... The battery leaked and some of the acid got on the pins of the processor, and it's all corroded. So that's going to need cleaning.  Where can I get a replacement battery?

Firstly i would remove the old battery and clean up the mess and get it working again. The A2000 will work fine without a battery. I had removed mine before it leaked and never bothered replacing it. My A2000 works fine.

Make sure you really clean out the mess using a good PCB cleaner. Then they say it is also good to use some sort of lemon juice or something to kill the corrosion.

Get a DMM and check the traces to make sure none are damaged. I had an A500 Plus where the battery leaked and damaged a trace. Managed to fix it by soldering a wire from one point to the other.

I would also carefully remove the processor and clean the socket and pins using the PCB cleaner. And maybe use some lemon juice to neutralize the acid.

Do the tracks look damaged ?

I would check the tracks / traces around the area were the battery acid leaked using a digital multimeter to check for continuity. If any are damaged you could try bridging them using single core wire. I had to fix an A500 plus that way after its battery leaked.

I checked the traces, theyre fine.  However, this morning, I powered up the amiga, and now im getting a green screen.

Iirc a green screen is an indication of faulty ram.

Did you try disconnecting all the Zorro cards?
