[Apple 1, or other rare machines]
Depends.
I'd pay more for a working Replica I than a broken original.
I probably wouldn't, but the first thing I would do with broken original
is lower its value (?) bu repairing it. Of course I would use parts as
close to the original as I could, and I would document the repairs. But,
yes, I woudl take a soldering iron to it to get it working again.
While I don;t have an Apple 1 (and don't _pariticuarly_ want one [1]). I
have 1 or 2 machines that are considerably rarer. And yes, I've replaced
chips in those where necessary.
[1] OK, if somebody gave me one, I would accept it with thanks. And I
would look after it. But if I won the lottery or something (difficult,
since I don't enter :-)), I would not spend the money on an Apple 1.
There are many other classic computers I would find more interesting.
