Got new ROMs which got me back to 'normal' where the machine will boot but only recognize 512K RAM with both boards installed.
Cleaning the CPU and socket with contact cleaner didn't help.
@sunderCan you tell from the photo above which chips these would be? I'm unfamiliar and it wasn't clear to me from the schematic.

If it's the MMU it should be pretty easy to fix, though most likely those chips are soldered on the board. They should just be normal SRAMs which should be easy to find, and ofc the two adders.
