This Amiga 500+ was recently purchased by Allan as a spares or repairs project because like a lot of these the battery had leaked and wreaked havoc on the board and Gary. Unbelievably it did initially power up but when Allan tried to remove Gary for cleaning, several positions in the socket broke loose and the Gate Array unfortunately lost a few legs. Allan asked for help so lets get it fixed.

Thank you so much for bringing this A500+ back to life. When you were explaining to me what work you had done, I was amazed. Now watching the video, I am blown away by the effort and skill put into this project. Opting to leave the traces clear was definitely the right choice. This A500+ is now truly unique! Thanks again.

No problem, just happy to see another Amiga brought back to life.

Nice job on redoing the chip legs, and much cheaper than trying to source a new Gary.

Thanks for the great vid, I got an a500+ of eBay and lucky Gary was ok, I tried to fix the motherboard, but gave up and got the A500++ pcb and moved all the parts over. Still working today 😊

Many thanks for another very interesting and entertaining video. Over a large number of videos I've seen you use a variety of tools (eg irons & tips, pens, desolderer, &c.), materials (eg wicking) and solutions (eg flux, vinegar, varnish & IPA). Have you made or have you considered making... A video that covers the key... Tools and accessories. Your choice of solder and flux. Iron temperatures and tips. Your preferred choices for wick and any other materials. Useful cleaning solutions. I think that others venturing on to the nursery slopes of board repair would be very interested in these things. Many thanks again for your commitment to making such an excellent channel.

Nice video. Always good to see what others may consider scrap being repaired (I mean Gary here) :)

Get well soon mate !!. It should have been hard recording and editing this one. Take care !!! Quick suggestion: in similar cases, I ended up using another socket between the one in the motherboard and the repaired chip. Too scary and fragile legs if I need to remove the chip again ;-)

Excellent work saving another Amiga! 👍

I've definitely put things going in the wrong direction on a PCB before. It happens to the best of us from time to time.😂 I hope you're feeling better soon!

Nice video. Thanks for leaving the 'mistakes' like the diode. That is great learning for the interested but inexperienced of us.

@wimwiddershins 3 месяца назад

Nice repair. Gary copped the worst of it from that battery but the board doesn't look too bad. Making videos while you have the flu, must be made of tougher stuff?😁

Hope you're feeling better. Hilarious the microphone thought you were background noise 😂

@CRG 3 месяца назад

It's crazy isn't it, but it's the only thing I can think was happening. I am feeling a good bit better now. Still coughing but very much on the mend.

@@CRG You did well considering. I'm usually the epitome of a sick man and struggle to do anything 😂

Excellent work dude. I felt your pain as you watched those pins drop like flies.

"We can rebuild him. We have the technology. We can make [Gary] better than he was. Better, stronger, faster." 😁 Come for the retro computing, stay for the installation of umpteen prosthetic legs on a badly maimed DIP IC.

We love you Gary 😊. Nice video

@craigluft7453 3 месяца назад

when you give chips names like Gary or Agnes, they'll be loved enough to get arduous leg transplants 30+ years after they're built

@pvc988 3 месяца назад

Solder itself is good enough corrosion protection. No need to introduce the lacquer. As for the battery diode, using Schottky diode is a better idea because of much lower voltage drop.

@CRG 3 месяца назад

True, but it was all I had to hand. I can swap it out for Allan at some point in the future if he likes. He is local to me, so it's not hard to do.

@Mind-your-own-beeswax 3 месяца назад

Job well done especially when you’re under the weather

@ownpj 3 месяца назад

If you had cut the battery trace between the other pair of pads you can mount the diode on the topside using the existing pads.

@RavenWolfRetroTech 3 месяца назад

Nice save! If you have to remove Gary again maybe put it in its own socket to stack into the soldered one so it is not subjected to insertion and removal stress?

@panopolis8051 3 месяца назад

excellent

well done good job

@boydpukalo8980 3 месяца назад

Impressive, but insane to solder soo many legs onto that chip!

@Breakfast_of_Champions 3 месяца назад

Mr. Gary, do you feel like a true survivor now? - It was only flesh wound!

@Nukle0n 3 месяца назад

If an obviously broken socket is stubborn on removal you can always cut it into smaller pieces that'll be easier to remove individually. Luckily it appears it came out easily here.

"Gary has, more or less, a full set of new legs." Gary can finally realise his dream of marathon running 😂

That's the thing that scares me about the 500+, 2000, 3000 and 4000. They all came with the dreaded varta rtc battery. All of them have leaked at this point doing a bunch of damage. That I have to look closely at pictures to see if it's been removed yet. I got stupid lucky with a 500+ The RTC battery for some reason was never installed into it.

@CRG 3 месяца назад

It is a real problem. This one isn't the worst I've ever seen but as you say by now they have all most likely leaked and wreaked some sort of havoc. I have another one with maybe twice this amount of corrosion that I'll get to at some point. Strange yours didn't have a battery from the factory. I think some rev8a boards shipped as just A500s without the battery but those also would have had just 512k ram onboard and obviously been in an A500 case.
