Quoting Tony Duell <ard(a)p850ug1.demon.co.uk>uk>:
I think what it comes down to is 'are you in this
for the money,
or because you enjoy repairing/using old computers'.
Right. I would, however, tack on a note saying that it's ok to try
and make money off of classic computing items IF that money is used
to recover costs incurred in your collecting activities.
