SOLVED: Replace 3.6v Battery on IIgs

[Alan Tuttle <news001@macgeek.org>]

Thanks to those of you who responded to my earlier posting asking how
to replace an Apple IIgs battery if it's currently soldered on.

What I did was hunt through my old broken logic boards and found a
Macintosh IIx logic board. This board's cool because it has two battery
compartments (vs one on the IIcx and later, as well as the IIgs ROM 03
board). I de-soldered both compartments without a hitch.

I cut the battery off the IIgs logic board, and was left with quite a
bit of wire on both terminals. I drilled two holes on the compartment,
one on each end of the terminal so I can poke the leads through them. I
then tinned both wires, using a hemostat as a heat sink so I wouldn't
damage the logic board. Finally, I soldered down the leads to the
terminals on the compartment. By using the hole method, you can still
place the battery cover on top of the compartment. Popped in a new
battery, then tested with a volt meter to make sure the leads were
soldered well. I moved the compartment around to make sure it was
secure. Turned on the IIgs, set the time/date, turned it off, left it
off for about 5 minutes, turned it back on and it retained the
settings!

I still have one compartment as a spare, so I'll do the same fix to my
ROM 00 logic board. These compartments are impossible to find in
Hawaii, so I'm fortunate to be a pack rat of broken logic boards.
