Probably my homepage, but the switch is designed by Geir Oyvind Vaelidalo
(he doesn't have a homepage yet).

Oops... A bit tricky, but it's not impossible to fix. This is how Geir
Oyvind did it:
Take a piece of very thin wire, it has to be thin enough to fit into the
hole of the CPU where pin 17 once were. Apply some solder to the end of
it, and bend it so it forms a little "hook".
Glue it to the top of the CPU so the little hook is pressed against the
point where pin 17 broke off. Now heat the "hook" with the soldering-iron
and you have contact :-) Connect the other end of the wire to ground and
your Falcon works again.
Geir Oyvind can probably fill in the details, he has done this several
times ;-)

Highly unlikely, don't worry about that.

You mean that they produced spikes that possibly killed something? Maybe,
but I really don't think this is a problem. What kind of relays do you
use?
> What about removing the whole CPU?
Not recommended ;-)
