Thanks for that tip - I'll have a look tomorrow at the local electronics
shop. I've been trying to do what I can right away since I'm a little
edgy about wet electronics. I figured that I should try to do something
as soon as possible.

I wasn't planning on throwing anything away, but what you say will
definitely help with the morale thing if everything doesn't go so well.

I was actually pretty surprised. There were drops of liquid under the
caps that looked like water at first glance, but were way too viscous -
almost goo. I think the plastic coating caught the moisture and it
somehow brewed in there.

Actually, the only component I've ever had to solder on my own computers
is ye olde capacitor ;) I've pretty much decided that I should replace
most of them, so that isn't much of an issue. I should probably sign up
there anyway, though. Thanks again.
The rest of the components are surface mounted and look to be okay
(apart from the RF TV circuits which are almost impossible to dry out
even with a hair dryer)

The main hardware I'm looking at is a couple of A1200s and a cd32 with
accelerators/third party add-on boards, so luckily this stuff doesn't
have a barrel type battery. There are button type batteries on the
add-on boards that definitely have leaked and I've already removed them.
I do wonder if they leaked beforehand or not since they were actually
quite dry. It could be chemistry at work too I suppose (certainly not
Thanks for your input!
