Another A500+ with leaking battery

[lewism]

Hello all,

This is yet another thread with an A500+ whose battery hasn't been removed, I picked it up on ebay tonight and took pictures as I opened her up and cleaned things up.

Pretty yellowed, but I do have another A500+ with much worse battery damage and a nicer case - might do a swap.

At least some good news, the listing never mentioned a RAM expansion!

A bit dirty inside but not the worst I've seen, but on to the inevitable battery damage..

So, off with the battery and on with the lemon juice (the lump of white stuff beside Gary actually just fell off the battery as I was removing it)

The last photo isn't the best but I was surprised by how well the area around U12 and U10 has cleaned up.

I'm packing it in for tonight, but what's the consensus - will this machine live again?

UPDATE 23/08/2011: Tested the machine today but no joy yet. Currently the power light flashes around 10 times, goes solid, and then repeats. I need to pop Agnus out and have a look because I suspect the battery leak may have gotten in there slightly (can see some green on some of the socket contacts), but first I need to pick up a PLCC chip extractor.

Ever optimistic though, I decided to give the case a good scrub.. gratuitous soapy Amiga shots follow.

Eeeeeek get it out, get it out, GET IT OUT!!!! veractor::explode

Drown it in lemon juice, get in with a toothbrush and after that give the whole motherboard a rinse with lukewarm water with a tiny bit of washing liquid.

[EDIT] Oh wait you have, nevermind then. Just a retr0bright needed.

That is a very neat job, it's hard to be sure, but I imagine you should have no problems with that board now.

Probably will give retr0bright a whirl on this once I have it working

Nice work Lewis, hopefully another one saved

Did you managed to get this plus working?

Commodore should have made some alterations to this machine while building it:
1) add a chapter named Preventive Maintenance, and another one called Corrective Maintenance in the user's manual.
2) change the silkprint a few centimetres to the left of the battery and rename it from DATA PATH to DATA BATH!
Anyway, great job mate

One of mine did just that but the damage was worse around the battery.

Flashing ten time and repeat, I can't remember if it was a memory error?

Anyway and post the steps you take of the repair / fault finding.

Good luck any way
Mike.

If you need more lemon juice, hit me up on PM. We use Citric Acid crystals (chemically pure lemon juice) in some of our scrubber towers at work.

If you think it needs a total bath, I'll send you some. It's going to be a lot easier than squeezing loads of lemons!

/me giggles childishly at the thought of towers full of "scrubbers"

We have quite a few dirty scrubbers at the rear of our plant (the trademen's entrance...) *cough*
