Which is why I have about 100kg of tools in the boot
of my car *all the
time*. And spare spare spare sound cards and the like...
As I've said before, whenever I demonstrate one of my classic computers,
I take along enough tools and test gear [1] to repair it should it fail.
That, of course, is the best way to ensure it doesn't fail
[1] Of course I have the schematics, etc with me too. If I'm
demonstrating a machine, somebody is going to start asking nasty
questions :-)
