Reminds me a few years ago an acquaintance showed me a Lisa he had received
from somewhere (long before the $/collectible value
took off).
It was not functional and off-gassing from the NiCd batteries was visibly
corroding one of the main PCBs.
I tried to convince him it would be a good idea to cut the batteries out
promptly, to at least keep things from getting worse til the time he took
a more serious look at restoring it, but he didn't want to remove them.
Don't know what became of the unit.
(Ho hum).
