Another A3000 with battery damage. Can we save this one?

[sev]

I have a A3000D that had some battery corrosion, Ive been working on cleaning it up and tryign to get this guy to run, but no luck so far.

It's a revision 8.9 board, I popped over the DIP ram from the chip ram area over to the fast ram area and removed the ZIP ram from the system. I did this because I have a suspicion the ZIP ram wasnt correctly socketed and I want to remove it as a troubleshooting item.

Basically the system when you turn it on, the VGA monitor gets video signal, but not much else. The Power LED does nothing but stay on solid.

The CPU and other chips seem to warm up, but nothing else happens. I have kickstart 3.1 roms in place.

Here are some photos:

I removed the capacitor with a bunch of corrosion under it. THis is what it looks like.

Where does this connect? looks like one of the pins goes nowhere.

i did something stupid trying to unsolder the 74ls174 chip right above the battery damage, i wanted to see if there was damage underneath and ended up lifting 3 or 4 pads on that chip...


i think im going to give up...
