Amigas in the attic...

[gertsy]

That's why you've gotta keep the trapdoor cover on. Let 2 of those little furry green creatures onto the motherboard and whoomph! they multiply...

Hi guys! I thought i'd give you all a quick update on the situation, so i've had her apart and yes the battery has leaked alot so i'm setting about getting some cleaner for it hopefully on Monday when I have some time. Some acid seems to have got onto a few IC's too, one being 'Gary' and the smaller one directly below. Amazing how the stuff has spread!

I'm hoping to still be able to sort it out, though i'm curious as to whether the acid in the battery can damage the circuit tracks, i'm guessing not but i'm not 100% sure.  I worked with eletcronics assembling boards and stuff for a few years so hopefully some of my meagre skills will help.

The disk box's arrived today too when my brother came over to ours and I found a hidden gem that i'd forgotten too - 'Tearaway Thomas'    :roflmao:    

Will keep you all posted on this epic project... (yeah, it feels epic too me! lol)  

Cheers, Shep.

Just clean it ASAP, use an old toothbrush and once you cleaned it just start the machine again, if it works, it will be ok.

Sadly it will damage the board. Get the battery off as soon as possible.

You said it! And whitout power any Amigan make an horror movie itself.

Since you're in the UK, you might be close to Amigakit.  They have many Amiga items brand new and, although they usually charge a good price for them, they are reliable.  They also have paid technicians in their employ to help you out.  I've been dealing with them for about five years and they have known how to help me, especially with expanding and modernizing my classic Amiga machines.

Good luck and welcome back.

Amigakit in the UK (http://www.amigakit.co.uk) has a good supply of classic Amiga hardware and software for repairing and upgrading your classic Amiga machine.  Some of it is new, some refurbished, but all is in good working order.  They also have paid technicians in their employ to help out with greater problems.  They've helped me rehab and modernize my classic Amiga collection for the last 5 years and been very helpful.  Here's their UK contact info:

Don't use them with an Amiga, please don't even hint that they could be used with the Amiga.

9VAC is not 12VDC. Perhaps nothing will break, but since the correct PSU is really easy to find, there's no point.

Looks like I got away with it because most of the circuitry on the motherboard uses the 5vdc.

Perhaps, it will have an adverse effect on the audio circuitry and floppy drive in the long run.

Some devices are tolerant though like this Yamaha keyboard I have which takes 9vac, 9vdc, 7.5vdc, etc.

That's subject to debate given it's in parentheses and perhaps, he's a nomad, or perhaps UK is University of Kentucky or perhaps, he works in USA and commutes.

I am afraid to say that it is a 50/50 chance that your Amiga still works. Remove that battery ASAP and clean the corrosion/acide on the board properly.

One of my A500 Plus's had very bad battery acid leak (the one i showed in the other pic) but luckily i managed to bridge a damaged track/trace and it has worked fine since.

Worst case scenario would be that you have to replace the motherboard. A500 ones will work and go very cheap on ebay. A500 Plus ones are harder to find, so expect to pay more. There is a user called airey36 (or something) on ebay and he usually has Amiga motherboards for sale. I've bought a 500 plus one from him.

If you do need to replace your motherboard make sure to retain all the socketed chips including the Agnus, Kickstart, 68000 etc.. I would just retain the whole board with all the chips in their sockets to avoid losing them

Depends how close he lives to Cardiff

What I do....

I gently rock the battery back and forth till it snaps off... Do this very carefully and avoid scratching the board. Then I get a cotton bud and clean the area with vinegar. Then I mix some Baking Soda [ Sodium bicarbonate ] and neutralise the area of vinegar. Then clean with water [ damp cotton bud ] and dry. Some folk use a hair dryer on a very mild setting... I don`t.

I have done this dozens and dozens of times.

Regarding batteries leaking, I just removed a couple from the A501 memory expansion and the batteries had leaked.  But the 512K still works-- I guess the leak was isolated from the main circuit parts that make a difference.
