Some machines (esp old ones) have been modified and you may want to
bring it back to its nominal state (esp if you are investigating
some strange behaviour).
Another example is the 9825A where a flat cable does not follow
the convention that the red stripe should be near side of the
connector with the little triangle. On a machine with voltages
ranging from -20 to +20 you'd better plug in stuff the right way.
Having said that, I usually take pictures of the machine as I take
it apart to make sure I can go back and check things. In the case
of the 9825A I assumed that having the service manual (original with
readable photos) would be sufficient. False! I had to check the location
of the ground connections to be sure that the connector was going in
the "wrong" way (red stripe away from the triangle).
In fact the same flat cable plugs in the other way round (red stripe
near the triangle) to the I/O connector, which leads me to believe that
HP people at the time either ignored or were unaware of this convention.
