No worries. I’ve now got three myself plus an A1200 in need of restoration and an A600 coming soon. Love the Amiga.

Danke. Ich habe eine Vorliebe für den A320 und konnte die Amiga-Version nie fliegen. Deshalb freue ich mich darauf, den Bau fertigzustellen und zu fliegen, als wäre es 1991!

You can transfer the 4 RAM chips from the damaged mainboard to the working one along with the matching caps. And using JP2 and JP7A you can configure it with either extra 512K Slow RAM (recommended, because most A500 games want this configuration) or a total of 1M Chip RAM. ;)

Great repair Jess nice to see it spring back to life

Thanks Dave. Loved the G4 power book vid. That's an interesting machine! ;)

same thing happened to me... button battery leaked got to clean it before further damage other than a keyboard letters QAZ and 1 ! didn't work still able to use the 1 on numkey pad. Gotta still love the Amiga. I now use the WinUAE...on PC.

Yeah, it’s so sad when these old machine fail due to the batteries, but winUAE does keep the Amiga alive. I love using it when I fancy a quick game of lemmings at home. :)

OCS Amigas rarely need a recap tbh. One of mine was a lot worse than yours and I mean a lot. After bathing it in white vinegar and generally cleaning the board afterwords with IPA. It still works just fine.

Yeah, I’m very happy to have it working again. The old board hasn’t been scrapped. I may periodically work on cleaning it up as a side project. :)

That board is beyond any practical repair. I am certain that many of the PCB traces in some areas are not just damaged, but gone entirely. They will need to be entirely reconstructed. Luckily you had everything needed to make a working machine.

Yeah, it’s taking a while to retrobright that’s for sure.

That was one of the worst boards I've ever seen. Normally the 500 get a little corrosion from the expansion but that one was terrible. Maybe you'll get the chance to try and repair it one day. The PCB explorer is a fantastic tool to help identify damage traces. It looks bad but I'm sure it can be saved. For now though you did the right thing by swapping out the board. Looking forward to see what you do with it next, lots of upgrade options.

Cheers Glen. I appreciate that. I seem to remember you yourself tackling a nasty looking Amiga PCB and doing fairly well. I will keep the board and once I have microscope I may have a go at seeing how badly damaged the machine was. For context here in Austria a work A500 will sell for €150 to €250 depending on what’s with it. This was €50! So I knew the moment I saw it, it had been battery bombed. Just had no idea how badly!

Move over Frontier Elite, A320 Simulator is the what the cool kids use to test Amigas! Nice to see a working machine in the end you can't save them all and that's some real bad luck with the RAM expansion causing so much damage, I'd expect it on a 500+ but you usually get away with it on a normal 500 :(
