While I still have tons of Apple II stuff laying around, I've never
had an Apple III.  I however have 3 Apple III power supplies because
about 25 years ago, a computer store had a bunch and were selling them
relatively cheaply.  I'm using one to power my Atari ST after its own
supply blew.  I was considering using the Apple III supply for my Moog
resonator, but after a few minutes of it turned on, it suddenly
smoked.  Same thing happened to another Apple III supply several
months ago.  So I'm down to the one on my Atari ST.  Those supplies
apparently don't age well.
