I perhaps take a slightly more permissive view. I am happy to use modern
parts if they allow me to keep an old machine operational AND can be
installed and removed in a non-destructive manner.
For example my PC server 500 has an unreliable floppy. I intend to add a
GoTek board so I can update the ADF files safely.

There used to be places that re-built drives after a head crash. Not sure if
they still exist.
