Thanks for all that info. I've saved it all for future reference. As
for touching the power supply to discharge static, I read a long time
back not to do that in I think Rainbow Magazine (Tandy CoCo magazine).
FWIW, I never practice what I preach - like you, I DO use the PSU to
discharge static (I work on my PC on a rug in winter - installed 20MB
of RAM no problem :) I heard of the 1-megohm resister deal and forgot
about it (I don't have a megohm resister, actually, and used the wrist
strap without one for a long time - contrary to the wrist strap
instructions!) Guess I best get one sometime, if I use the thing
again. I do still like using anti-static pads for placing things like
memory modules and cards on while I'm working. That way I don't run
the risk of damage while I set the module or card aside for a moment.
I still think most should like you say, have a qualified tech do the
work or get a wrist strap. I still think if the PSU had a ground
problem a person could still get zapped... But then again, these days,
the PSUs are built better. In the Tandy CoCos, they were encased in
a mesh metal enclosure and some had wondered if that was safe to tell
people to use that to discharge static.
