Default My 500+ Project

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.

Gary Socket:

Not yet cleaned up Gary Chip:

Bad battery!:

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.

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

Good Luck! I just recently (two months ago) restored a 500+ motherboard that I recovered from storage in a barn. It was a complete mess, but it is now up and running happily housed in a reg A500 case. Now to finish restoring a few other things I got such as the Midget Racer accelorator and I'll be a happy camper!
