The dreaded leaky RTC Battery

This is the aftermath of a leaky Varta battery on a 256TC. The removal of the RTC IC and a VDU SRAM shows the extent of the damage.
The PCB traces are super fine and seem to disintegrate by looking at them.

Ouch! That's going to be "fun" to fix :-(
I assume you've neutralised the alkaline with something suitable? Looks like there could end up being a mess of bodge/patch wires in somebodies future.

I have a Mac SE/30 that had Alkaline corrosion from leaky caps. While I cleaned it up and it worked fine for a year, it's now stopped and I'll need to send it off to a professional to get it to the "next step".

I wish you luck!
