your the amiga hero theres nobody who works harder at saving them than you come on people lets send chris some moola lets all chip in so he can buy some new gear and keep him running.
Hi chris, i feel for ya buddy.. i think people getting these boards repaired just for resale free of charge is real shitty, and are taking advantage of your kindness. I think you should be rewarded for the work you do, which is top notch. I really enjoy your videos, and PiMiga too. Thanks for everything chris. 🌟👍
The black stuff on traces is *NOT* from battery juice. It's very common on arcade boards too (I've repaired thousands of them). The black stuff is caused by moisture because it was stored in a damp place for many years. It just "looks" bad but it's fine.... as you discovered, no broken traces where the black stuff is....
Genuine question @g4z-kb7ct. At 5:45 Chris exposes the copper and the black mark appears to be in the copper. Surely if it was moisture it would be green(?)
Yes these Boards can be saved, After Hours of Work, yes Dr Chris's Expertise is on Show, Rescuing another Amiga for Resale by a USER ... I can only hope that these Video's Let others see how it's done to Fix their own Rev 4's, which were working in 1996 before it was sunk in a boat accident & Retrieved by a Mechanical Claw ..
Chris, I need help with my 4.1 board. When I received it there was only a black screen. Since then I have replaced the processor socket, the Agnus socket, socketed and tested the third and fourth line of RAM ICs, socketed and tested U540 & U541, tested all the custom ICs, repaired 8 traces around the battery on either side of the board, traced every pin of Agnus, the processor and the ROM, watched all your videos...and I still only receive an insipid green screen. What pray tell should I do next?!
I know you have much lust for Rev4's but it's still impressive to watch. Thank you for what you do. :) Where do you find the layout files for Sprint? Are they publically available? I chuckled at the dog hair. I have a cat, he gets his pubes everywhere when I'm working on something under the mag lamp.
They all get slapped if the battery is left in. While the “GP” brand is less leaky? They all leak and kill them. Rev4 boards i hate as the ram is 32 chips vs 6 of the rev6 and the logic layout is more prone to damages. Also it seems like they find r4 Boards in a old bucket at the bottom of a lake for some reason
Hey Doc, instead of stuffing boards with free parts (out of your wallet), why not send them back with a list of "parts needed"? Doing the fault finding for free is enough generosity.
well thats nice. but indeed counterproductive to what i do saving the machines. my own wallet yes but i have help from patreon members to save these things.
Fair point Sir. Personally, I'd be more than happy with a parts list. But I also have the experience and tools to do most of the repairs myself. Not everyone has that. For those people you are a fricken godsend.
Thanks For all the Great Vids ❤
wow thank you so so much!
Chris you are AMAZING!!!!! 👍👍👍👍👍👍👍👍
Watching you crunch that socket is almost as addicting as eating a bag of chips.

Great job Chris. Keep up the good work. Nice content and thanks for sharing with us. Greetings from Steven from the Netherlands
Thanks, I appreciate it.👍
I am starting to run out of the Rev 4 boards to send you. I promise I will keep looking!
Another great Video Dr Chris. 👍🏻

Nothing stopping him from charging.
Chris has the same reaction to Rev 4's as I do when I hear the name Mehdi Ali.
Wow! Not an easy fix but you sure made it look "easy".

I get a buzz out of seeing it fixed,and I'm just a voyeur...lol.
Holy boing balls, batman!
Great Video👍
You probably get this question a lot: What's that software you are using to track where the lines go?

Does diagrom boot?
@@ChrisEdwardsRestoration Just a flashing green and red screen that turns grey and then settles on green.
What is the circuit diagram that Chris is using and where can I get it?
Sprint layout and the files are on google search from a github share

Well done Dr. Chris. What is with all these Amiga 2000 ver 4.? Mobo's?
Is it possible that none of the ver 6.? boards did not suffer the Varta fate?
ALL Amigas with a battery suffer the Varta fate including B2000 rev 6 boards.
