I'm guessing a floppy drive
on the top case over time
Strange wire for a very old machine
Star screws
Green side down on the keyboard
No ribbon on the keyboard
ie the muticoloured one on
the previous machine
And that rare and magical C=
Green and no ribbon
So that's where the wire goes
Not the battery you think it is
Keeping the fat lady held down
I'm glad they sorted that mess
out with the later boards
And she's alive
Definitely a red light area
