Hey guys.
Thanks for the tip. I opened it yet again and inspected further under a
loupe and sure enough I noticed damage I'd not seen before. I removed the
battery and cleaned up around it some more and mitigated the damage. The
acid seems to have only migrated a few millimeters towards the adjacent
7400 series chips and only slightly affected the ground plane. Here's a
photo:

I ran this system for hours last night and it never hiccupped.
I don't know what "AGA" means. There have been a couple sales on eBay
recently for stock systems without the upgrades this has that both sold for
$800. I sold a stock 25Mhz system earlier this year for $500.
Again, thanks for pointing out the problem with the battery.

Sellam,
I am an Amiga expert. If you don't remove the battery asap you are
going
to lose this system. I am amazed that it still
works but that isn't
going to
last much longer. You stated that there was some
corrosion that you
cleaned
up so it may already too late to save the
motherboard. The acid from the
battery will migrate along the copper traces and there is no way to stop
it
nor repair it. I would never buy this system.
GOD Bless and Thanks,
rich!
Eh, looking at the pictures the battery damage is very little. It is a
decent candidate for saving. Action needs to be taken quickly but it's in
way better condition than ones I've attempted to work on.
I do see some flaking north in the copper traces of the battery.
I still wonder if osmeone will reproduce Amiga 3000 motherboards where you
can either move over the customs but also has some modern add ons.
As well as a replacement board for the Amiga 600 :-)
At $800 though... not AGA.
