Very cool, and not the worst thing to repair. My 11/05 has been sitting
around for years with some sort of power problem which I've been dreading,
but this encourages me to work on it.
I also appreciate the links to the archive.org scans of the manuals &
prints. I have boxes full of physical copies and I'm reminded I should
check before committing to scan any of them.
