Background:  my wife is on the Board of Directors of Camp Adventure,
a summer camp for handicapped kids (spina bifida, muscular dystrophy,
and that sort of thing), and several years ago, when Z-100's got
real cheap (e.g., Clarkson University was selling them fully loaded
for $200), the Camp decided to buy five of them in order to offer
computer classes to the kids.  (Part of the reasoning was that even
if some kids muscle spasm dumped a Z-100 onto the floor and ruined
it, as cheap as they were there would be no great loss.)  Over the
years, the Camp acquired four more (this is in addition to the
personally-owned Z-100's I use in my home office, the one in my
University office, the one my wife uses in her home office, the
one with a Gemini board that sits largely unused, and a couple of
spare-part "junkers"!)  As my part of the Camp, I volunteered to
(try to) keep them all running  :-(

Fortunately, we've never had one pushed off a table or anything like
that (although four of the five monitors shipped from Clarkson did have
their width control (on the backside) smashed because of insufficient
packing or poor handling during shipping), but I just had the first
power supply failure (it blows its fuse repeatedly) in all these years.
One of the "junkers" had a power supply which seems to work fine, but
now I won't have any spares left when the next one blows.

Years ago, Gern (does anyone know his email address anymore?
gern@lonex.rl.af.mil is apparently outdated) provided an FAQ write-up
and a schematic (via snail mail) on the Z-100 power supply; I've
looked at the schematic, and while I'll try poking around looking for
obvious faults, from prior experience I already know that I'm usually
not very good at fixing things.

Does anyone know anyone who DOES fix Z-100 power supplys these days?
(And hopefully without charging whole arms and legs!)
