Please tell me you're joking.
No I am not joking...
A PCB cut and repair is (a) generally a useful modification (either to
trace a fault, or to improve the machine in some way, and then to go back
to the original configuration). And (b) it's bleeding obvious what's been
done.
You're telling me that permanently altering a computer in a museum setting
by cutting traces and modifying components is less intrusive than swapping
screws? Please explain how this is the case.
It is _not_ obvious that the original screws were,
say, Bristol Spline
head if they've been replaced with Pozidriv or whatever.
It is equally non-obvious that the modification was done contemporarily or
prior to the museum taking possession.
My moan from the start is that there is no good reason
to replace the
original Bristol Spline screws with anything else. Period. And if there's
no good reason to change something, you don't change it.
In this case, there was what I would consider a good reason: Jules didn't
have a Bristol Spline tool on him and wanted to swap out the screws to
something more serviceable for future work. As far as I'm concerned (with
the caveats I have expressed) that's reasonable.
When there is a good reason to change something, then
I see no problem
with changing it, provided you document the changes and attempt to make
sure said documentation is preserved.
I agree. So how do you rationalize the cutting of traces and
modifications of parts to make something work to be acceptable but the
swapping of screws to make something more practical to work on is
unacceptable, given in both cases you fully document the alteration?
Your logic does not compute.
