[comp.sys.mac] WARNING--2 Meg Upgrade

Just a "look what happened to me" story...

Our original 128K machine was lovingly upgraded to 512 (by Appple), then
to 1 meg.  Our friendly neighborhood Apple salescritter told us that there
was this wonderful clip on board that would give us yet another meg.  Thinking
that this was a wonderful idea, said board was purchased, installed, and
ran without a hitch.

6 months later (or so), I started having what looked to be power supply
problems.  In fact, they were classic symptoms.  Apple fix-it-critter
pulled out the scope and said, "ick, not enough power.  No wonder it doesn't
work right" and tweeked the supply to specs.  I took it home.  It died again.
This time the fixcritter replaced the supply, set it to specs and I took it
home.  It fried itself AGAIN!  Fixcritter was perplexed.  He thought the first
new supply must have been bad.  He replaced it again.  It seemed to work fine
for a bit (this time in the store), then started fluxing yet another time.

It was the damn board.  Removing it, the machine has been wonderful for
2 months.  If you get yourself a 2 meg upgrade, check it out before replacing
the power supply.  (by the way, the memory itself on the board checked out
fine, so that is not an accurate way of finding out if the board is causing
the power drain)

Mikki Barr!
