The general discussion list is appropriate for
discussion of the following topics:
* classic computer hardware, software, and documentation. We
define "classic" as "at least ten years old, plus or minus cool
factor";
* computing in general ten or more years ago; and,
* fringe topics relevant to the pursuit of the hobby, such as
electronics, moving heavy equipment, and cleaning techniques.
Sounds like electronics to me.
I've always understood that to mean 'Electronics _as related to old
computers_' In other words, asking how SMPSUs work is OK (particularly if
you're repairing a PERQ 1 that's just gone bang), asking how to fix AA5s
is not.
Otherwise, since 'moving heavy equipment' often involves motor vehicles,
then discussions of how to fix your car would be on-topic, etc...
