Indeed very sad news.
Altought you've done your best on reviving these computers, you don't have to
blame yourself but these persons who never took care of the amigas.
So yellowed, with battery leakage, and so bad shape only means they've
been abandoned for a loooooooooooooooooooooooooong time, eating dust
and having their inner parts rotten.
So, the only thing it can be done in this case is to save whatever it can be saved,
even the enclosure (retr0bright) and use these parts as a replacement on working
computers.
Under my point of view, to trash a working amiga, or let it rot into the attic is
a CRIME.
