I did say that cheap commodity hardware is the reason
I don't repair
defective components, I just swap them out. However, that's not the
reason why I don't try to repair collectable kit. The thing *is* that
for pretty much my entire working life - i.e., the last 2 decades -
this has been the case, so I never learned electronics or how to do
component-level diagnosis or repair. And what's more, the skill is
more obsolete now than ever.
The last is a complete non-sequitur.
OK, for most of us classic computing is a hobby, and a hobby is something
you do becuase you enjoy it, but that doesn't mean you don't have a learn
particular skills for that hobby that are useless elsewhere (for example
in your job).
