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:
https://flic.kr/p/2hxjBv3 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 On Sat, Oct 19, 2019 at 10:18 AM Ethan O'Toole <[email protected]> wrote: > > Sellam, > > I am an Amiga expert.
