Note: It did occur to me whilst editing that I could have scratched the traces leading to / from those 2 sockets and soldered a wire there. That might be tidier!?! I've also told Andy that if ever needs to send it for anything else, I could fit a black SDMAC socket, and replace those 2 smaller sockets, as well as fit turned pin sockets for the Kickstart ROMs - if he needed / wanted any of those things doing. He wasn't fussed about the colour of the socket, but someone might be! The wire could be re-located again at that point, and perhaps be tidier. In any case I would expect those GALs will never need re-programming. Wrangler Amiga - www.youtube.com/@wrangleramiga896
Yeah, I was going to say, that would've been the way I'd have done the bodge, you can access the traces leading from those pins pretty easily so I'd have removed the resist and soldered the bodge wire directly to the traces, then if you're paranoid clear nail varnish or more hot glue on top of the connection.
I would not have thought of using just the iron with low temp solder to remove such a large chip, but you made that look easy! And I noticed you used small blobs of solid hot glue and melted with hot air to limit the amount of glue and make a neat job of it -- really nice idea!
£500 for a chip. Wow!!!! Did I hear that right? That is a whole nother level. I would be so nervous. If anybody can do it properly though, you can mate! Top job.
Thanks Brad =D Yeah, they are nuts expensive - cannot see ANY for sale at the moment. The last one I saw sold for over 400 euros and I think that was a rev 02. They are just so rare to find seperate from a motherboard. You could argue is cheaper to buy a complete dead A3000 machine....
That PLCC socket bottom is so very easy to remove. Just use a thumb and press down in the middle, while holding it in the air, and all those plastic pins just crack in one fell swoop. I’ve done this many times without problems.
Excellent skills! The only thing, I wouldn't glue the plastic plate under the chip....I would just place it there and press it with the chip. I usually break/burn traces since I don't have the patience like you. You are the true Master.
If the chip became slightly loose for whatever reason, the plastic would be able to shift and wedge in so the chip can no longer be pressed in, had that happen to me a while back. I glue them from now on.
Mate your patience with this was superb 😂. As Wrangler said straight away, I should’ve started with reseating the kickstart roms rather than faffing with other stuff for hours beforehand 😂.
If possible I would recommend getting some flush cutters for taking out the base of the socket. The one you are using is way to big and not a flush cutter so it would have more chance to bend the pins by accident.
im looking forward to the FPGA SDMAC, my 3000+ has an 02 and it causes issues with the onboard scsi with accelerators, my 3000 was made into a 3000++ after the battery did what they do the PCB, at the moment is running a 4060 early bird card without issue
@GadgetUK164 Is the AA3000+ the prototype of the orignail AAA Chipset idea before changing it to the AGA Chipset? or is it a complete remake of the A3000
The AA3000+ is based on the 3000+ I think (which Commodore never released)! It provides AGA support to the Amiga 3000 design, adds the DSP and tweaks things on the board to make it better too.
Plastics can hold static electricity. So i’m not sure about putting a plastic cup directly on the chips. Paper is an insulator. So best put a small piece of paper underneath it?
Are you based in the United Kingdom? If so, can you please fix some consoles for me? I’m having a hard time finding people who will do the repair work I need! Not only do I have a Neo Geo Pocket that won’t power on AND a Pokémon Mini whose A button has seen better days, but I have a PlayStation 2 whose ModBo may be why it can’t load PS2 games anymore and an original Xbox I’d like the life of prolonged please! I also want to be able to source replacement lasers that work and will last for my Dreamcast, PSone etc but most people I ask tell me to get ODEs instead! I’d rather keep my systems (as) authentic (as possible)! Thanks

Yet again, GadgetUK at the cutting edge of retro repairs. :)
Long may you continue to impress.
Thanks very much =D

Thanks James =D I did remove the odd partical of glue there off camera too before it went back!
Sweeeet! Friday night 3000 fun!!
In all fairness, a 3-month repair would be pretty quick for GadgetUK 😂
That is a beautiful PCB there. Seems a really nice A3000 implementation!

It's just a rubbery style of glue - very easily peels up with IPA!
Wise words you say about how to face life: "Si vis pacem, para bellum".

Thanks! Yeah lol, another Occam's Razor - simplest explanation was always going to be the most likely!
I hate working on functioning PCB's. I'm always terrified I'm going to break them.
Nice work.

I was wondering what the model number of that Sony Bravia shown at 13:45 is... Love watching your videos, keep them coming!
Thanks =D I need to check!

Nice work!. Low melting solder paste with hot air does the same. Maybe consider a hot plate?
first time i see one of your video but i'm confused : what is Amiga AA3000+ ? whats is sdmac ? a little resume will be well for beginner :)

The "plastic cup" - socket, is ESD safe plastic!
👍👍👍👍👍👍👍👍👍👍👍👍👍👍
open heart surgery on the Amiga....
my god the size of cotton bud at 53.22.....😉
