The fact that your machine powers up is a little encouraging, but you have
a bad situation here. My Lisa had this problems and I was never able to resurrect
the I/O board. I did get the motherboard partially working before I got a good
deal on a replacement. I had to solder wires around many of the land patterns;
they appeared to be open underneath the connectors. I got the machine to boot,
but the parallel connector didn't yet work.

I'd follow the instructions on the web pages with the I/O board and the motherboard.
(Remove the motherboard from the metal chassis first.) You can use a toothbrush to
help remove the green guck. On my Lisa, the worst damage was to the circuits that
had power when the Lisa was turned off: +5 volt standby power and some circuits
in the I/O board. Due to electrolysis no doubt. The other boards and the power supply
were unaffected.

I'd like to add, though, don't be afraid to use lots of water. The vinegar is a good idea
to stop the activity of the battery goo, but be sure to rinse thoroughly. You can use a
hair dryer on low to dry the boards, just be careful not to overheat any components;
keep moving. Make real sure the boards are dry before applying power.

Good luck!

It's probably toast, but you might be able to fix it depending on what's been broken.
