Hi All, my 500+ finally arrived and so I eagerly took it apart and inspected it - not in the best of condition unfortunately and going to need either surgery or a heart transplant.

The battery has definitely leaked and some how caused corrosion to the Gary Socket Contacts which mostly disintegrated when I removed the Gary Chip - The chip itself seems to be fine and I was able to clean it up quite well.

Bad Battery Removed showing some surface Damage to the PCB - I wonder if this has killed the Mobo?:

There was also a tiny amount of rust on a couple of the Shields but it hadn't done any damage to the Mobo.

So Im hoping I can just replace the broken Gary Socket (AJ, might need your help on this one as I dont have a de-soldering station) to revive my poor 500+ otherwise it's going to need a heart transplant. :nervous: :eek:

*runs away and hides*

What do you reckon AJ, do you have the skilz to de-solder the Gary socket and help me put in a new one? (the installing socket part I can manage, it's the removing part I cant)

Damn that is a lot of acid damage to the mobo...  its crawled its way to many IC and sockets  so sad to see a A500+ in this condition.

The Gary chip should be okay, the socket might clean up well without needing to replace. A thin stiff brush and alcohol to clean away all the mess. The resisters on the right hand side of the removed battery look bad, maybe if you going to resolder a Gary socket you should replace these as well.

Best of luck! Hope you can revive this poor Miggy

Nah the socket is totalled - see the pic below (contacts are broken, some literally shattered when i removed the chip.

did you buy this as "working"?

Bought as "powers up but can't fully test". I'm not too bothered as restoration is half the fun. It might have actually worked as is had I not pulled out the Gary chip for a Look. :cool:

looking at the pics, I don't think it would have worked at all.

I could be wrong, but it appears there's tracks corroded completely through.

bit late now, but I would have tested it before removing the ic :p

Yeah good old hind sight, I underestimated how much corrosion damage there was to the socket - oh well, I'm putting out feelers for a new mobo and I might buy a 1200 when petro makes them available.

Are you wanting to sell the faulty 500 plus board? You can take all the chips etc out, just needing the component above the denise chip. Will take a photo and up it a little later.

Although my soldering skills suck ;-)

I was either going to keep it and use the chips for spares or once I hopefully get a new mobo sell the spare chips etc to recover costs. See what happens tho.

Buy two 24 pin sockets from jaycar for 60 cents each

Did you get this from the UK? If so, how much was the postage?

Shame about the damage, Most of the A500+ ECS compenents should fit in a standard A500 mobo that you could easily get from ebay.com.au, the only chip you may have problems fitting without adjustments is the fatter agnus. Good luck, would like to hear how you go with this.
