It appears battery "B-1" self-destructed. I see some leads, But no battery.

Yes, there was a battery there that had leaked, I snipped it off before
taking the pictures. This appears to have reacted in an interesting way
with the GRiD's casing (a fact that I just noticed while cleaning it up)
which may explain the interesting deposits. Perhaps it's the magnesium
the case is made of? (Not a chemistry buff.) I'm not seeing typical
battery corrosion here, thankfully.

Subject: Removing mineral deposits from circuitboards
So, here's a fun one:
See the picture(s) here:
http://yahozna.dyndns.org/scratch/gridcase/
This is in a Gridcase 3+ I picked up last week off eBay for what seemed
at the time to be a pretty great price. Heard some stuff rattling around
inside so I opened it up before doing anything else and what I seem to
have is a few large mineral deposits on the main circuit board.
Any tips for removing this stuff?
(Also, as an aside -- my mails to this list are clearly making it to the
list, but I never see my own posts/responses anymore... any ideas?)
Thanks,
Josh
