My trusty old Amiga 4000/040 have been sitting idle for far too long. 13-14 years at least. Before it got decommissioned in favour of a Windows box, it was not all that reliable either. After a while of being powered on, it started to go slow and then freeze outright. So at the very least it got a heating issue.
This can be remedied by cooling down the CPU some more I assume, and luckily I got plenty of CPU cooler fans lying about. So that should be a simple fix.
A bit more serious is that the old battery have leaked...

It's not spread too far though, and the corrosion isn't terribly bad as these things go. What is affected is the 10k resistor network SIP8 package, the HCT174A flip-flop chip and four of the eight 4.7k SMD resistors. Two of the pins on the rightmost HCT166M shift register chip is a bit dull as well.
Parts are ordered, and whilst at it I went ahead and ordered new caps for the motherboard and the CPU board. And a couple of other bits, like a coin-cell battery replacement and a 4 gig CF card 'Hard Disk' replacement.
It'll be a while until I got all my ducks in a row and can get it all fixed. But that is fine. It'll give me time to go over the rest of the machine with a keen eye out for potential problems.
First on the agenda is having a good look at (and test of) the PSU. I suspect that may need a recap job as well. The floppy-drive will need an inspection. Last but not least, the front plastic cover is now more brown than off-white, so it'll need some treatment.
Plenty to do in other words. Will update as the project snails along over the following weeks.
