The good news is that MOST (but certainly not ALL) problems with the model
1 power supply are nothing more than a blown fuse! All that is usually
needed is to solder in a new fuse.
The bad news is that the case is glued together.
Fortunately the glued joint tends to be substqantially weaker than the
rest of the case.
Although some, such as Tony, might have a much better way to open the
case, brute force will usually do. Swinging it by the cord (now I'm SURE
that Tony would have a better way :-), slam it down onto a carpeted floor.
Gradually increase the level of violence until it cracks open, without
getting rough enough to shatter it all over the place.
Solder in a new fuse, and glue the case back together.
A Dremel saw might do the job, but this is the technique that we used at
the 6th? West Coast Computer Faire to repair half a dozen of them. (Show
management insisted that there was NOTHING WRONG with the power provided)
I sold some of my model 1 stuff at VCF, and Eric got most of the rest.
