- E485 - The final installment from the R6 death machine. sometimes you just got to let the old girl go. I did all i could but was unable to save this unit. it Can live on again with a re amiga system. but I don't do that on a complete build.
Its Dangerous to go alone, take this!

And machines like THIS is why I did the ReAmiga! to repair doorstops like this
ReAmiga... The only hope.
Is a reAmiga basically un unpopulated board that I stuff chips into?
@@RarefiedErroran over simplification but yes!
@@danielktdoranie oh ok, even though I was an electronics technician back in the day, I havent touched a soldering gun in 30years (hands too shaky now)
Don't knock yourself over this Chris, youv'e done your very best, and spent many more hours on it than most repair shops would have. Like you say, not everything can be fixed, especially when your the 3rd person to attempt a repair.
Thanks
wow thank you so so so so much!!!!

I wish I could just give you a massive hug for bringing all the Amigas to life 🥰 and filling my full times with knowledge 💖
Your commitment is amazing 😍
@@petamichaelagergen2418 thank you for that. I tell you many times i could just use a hug... hahaha
It is CRYSTAL CLEAR from this video just how much it bugs you to not be able to save every machine that lands on your workbench! Don't worry man- they don't ALL have to get fixed. Besides, I think you are right on the money with the idea to strip that motherboard for parts. sometimes the amount of time spent to fix stuff isn't worth it and those nifty new projects (like re-amiga) need parts too. 👍🙂
It seems like every time I tune in you're working on a 3000 that's given you fits. It makes me kind of nervous because I have with 3008's work and I'm afraid to ask you about it. Not because I don't trust your skill but because I don't wanna wear it out. You need to take care of yourself man you're a resource that we need.
I had to give up on my rev 6.1 Amiga 3000 T PCB. I finally found a clean (cleanish) motherboard that had been robbed of its chips and fixed and swapped in the working chips. Damn you batteries!
The only thing that comes to my mind is to resolder all the soldering points on the board. Damn electrolyte can do damage in very strange places.
I know it's a strange idea, but after the wars with batteries, not only in Amigas, but especially in music synthesizers... such a job allowed me to bring a corpse to life more than once.
Do not give up... 🤞
Watching this was like a horror movie for me as I have one A3000 and it works just perfect. Scares the hell out of me that it would start to fail. It has CS060@50Mhz, CV64/3D, Xsurf etc. I have bought a faster 060 but I don't dare to change it to the CPU card just in case something goes wrong. Its fast enough as it is.
Ofc there are days when it won't boot. I open it, press some chips down carefully and touch the power wires and it boots again and stays on nicely. It has the original PSU, which I think probably causes the occasional boot problems.
So happy with this comp.
You did your best Chris. Damn it is sucks that the board not is working. Greetings from Steven from the Netherlands
too many cooks spoil the broth! Don't worry, be happy! nobody will think less of you. Your still the KING in my book!LOL
Something of a miracle so many such old rigs are still operating at all - to be expected some are too far gone
You did your best. Sometimes it just doesn't work out. Again learned something new.
Yeah but i always feel personal guilt when i cant
No guilt. We all know, that you always do your best. Maybe it is something simple. Like a defekt of a power supply cable, or something similar. Sometimes we just stuff our heads with the most complicated solutions.
Thanks for the content as Always Dr Chris 👍🏻 I felt your pain with this journey 😔 Have a had a few of these moments myself and it really does get you down. All I can say is we’ve all been there. Unfortunately you cannot win them all 😉 A3000++ Candidate. “Q” went through the same thing I believe. Either that spare parts for another A3K. Cheers 🍻
Sometimes it's just not meant to be. You made the effort, but all efforts have limitations and I know what it's like to keep trying but sometimes it's just best to throw in the towel and move on.
It's going to suck but you'll have to go through "every" component on the board, not just the main chips, and check the signal on them, following the startup path to see where the signal dies. This will be even more time consuming. :(
Sadly not every Amiga can be saved, thanks for your hard work.
It really suck when you come to the point where you have to give up. But sometimes you do, it's just not fun feeling you wasted all that time.
The agony really comes through.
😢 Valiant effort there Chris. Sometimes they just can't be saved.
reminds me of an engine i once built didnt work so i rebuilt it probably about 10 times there was no reason for it to have no compression , i have built thousands of engine in my life time and never ever had a problem always start first click but this engine was cursed from start to finish it just never wanted to work so i had to give up it was the most depressing decision i had to make and tell a customer i couldnt get it going despite doing full rebuilds was bonkers and i have rebuilt same engine 100,s times no problems , so in life theres always 1.
Hi Chris your channel is great and I appreciate the outstanding effort that you put in to save our relic Amiga computers. Cheers
Dr. Chris, Time of Death😢
Have you tried turning it off and on again? LOL. Sometimes you gotta take a loss, great work but that board is cursed.
Sounds like the perfect candidate for a ReAmiga. Put another 30 years in the old girl with a heart transplant on a brand new board/capacitor/resistors/etc..... So long as the Amber chip and SuperDMAC chip are still good, everything else is avaliable. I thought you only invested 20 hours into these projects. Sounds like you went way overboard on this board. You cannot save them all.
this was filmed a while back. this is the one that caused the new 40 hour limit.
I'm a firm believer that in this unfortunate niche ultra expensive Amiga hobby environment, that technicians such as yourself should be charging a lot more for this type of service. A few years back I had some high level repairs done on my A4000, for this repair the technician only charged me about $70 or something ridiculously low. I see the same technician is now reluctant to take on new repairs as he seems to be mostly working on the re-Amiga builds. I can only assume this is because it is a lot more *lucrative* and less time consuming to build something from scratch, custom chips can be tested individually which doesn't involve potentially open-ended detective work.... These Amiga technicians were a rare species anyway and so it's sad we are loosing them and with it the ability to have these old machines professionally repaired. I don't know how much you charge, but in this current environment you should perhaps start with $500 just to look at the big box Amiga stuff. The reality is that the custom chips for these have become gold dust, and because of this so are the technicians to work on them.
I dont charge anything. I do this as a hobby and help to other Amiga enthusiasts. why? well I believe in the Amiga and I dont want it to die. I do get help from Patreon members who mostly kick in 1$ a month... yes a month, but it does help offset the cost of chips and repair parts and things to make it possible. Sometimes I even get help with return shipping...But I do it out of love for the platform.
@@ChrisEdwardsRestoration Yikes thats cool I didn't know that. It's then maybe worth being cautious and picky which projects you take on, personally I'd rather help someone who has owned a working machine for sometime which went bad on them, rather than someone who picked up a broken machine that has potentially been worked on and written off several times, with perhaps the expectation of making it valuable, opps sorry I mean working again. It's none of my business anyway, I just really enjoy watching you're content, and if you ever do charge for this type of stuff in future I don't think anyone will begrudge you. I'm looking forward to the next Amiga adventure.
Chair moans more than Mona.
Unkind people suggest that it is not surprising.
Patreon, dude. Like Jesus does.
Any fuses like the A2000
Also check the rom towers work in other A3000s
Parts board?
I wonder is trying something like the pistorm that takes over lots of functions on the board might boot. If it does, would that be able to narrow down the things that do and don't based on what the pi takes over?
I don't remember if the pi can boot from roms on a disk or if it needs roms on board.
If it boots that way, you can test to see what it can see of the board, and you know the functions that are handled by the pi.
There is no PiStorm for the A3000/4000 yet as of April 8th. 2024. Hopefully it'll come at some point.
@@kavanoz64 I was using pistorm as a shorthand for accelerator that provides enough functionality to bypass much of the board. That's why I said something like the pistorm.
Also i can't remember if you did a pin out on CPU but do the CPU halt signal Go low or do it stay high?
i did more off camera than was shown. 3 parts i have to keep it within a reasonable view time.
Are the caps in the correct way (despite incorrect factory board silkscreen designations)? Are the correct voltages pinned out to where they need to be?
yes. ill have the owner send her over your way. hahahah
One last question, Have you tested the reset line, i mean is it in low or high signal?
And how about Romem signal from Roms? are they high or low, as i am aware if high then it will not let kickstart Roms run code
I tested everything. As I said in a previous comment after three parts, I’ve done a lot of things off camera because I can’t have 40 hour episodes. I have to edit things down to a reasonable watch time.
i am sure people would donate money to you, for the work you do, if you asked for it,how about having a poll and find out.
Not everyone E Begs, especially wise older folks.
@@WyMustIGo ok then,and not everyone works for free,if we don't pay people to fix old amigas,soon enough they will only be glorified non working electronics.
@@runeingebretsen8378 I've been alive for 62 years, and money is earned. LEarn to stop begging. Young generation are a bunch of lazy tools.
@@runeingebretsen8378 The guy who owns the Amiga needs to open his wallet, not viewers! What kind of moron expects people to fix his shit free?
@@WyMustIGo not that young,53,and i have owned all of commodores machines,but i don't have the eyes or room to fix them myself.
I was wondering if you could just buy the motherboard PCB and pull everything usable from it, and just build a new 3000 from that? Maybe it would be more time consuming, but it seems all the components are "good" so ... Maybe doing that would make it right?
possibly, but thats not what i do. mr Hertell does that for people.
Hi Chris
Just wondering if Amiga 3000 Needs the daughter board in to boot, try to see if there is a bad connection or broken trace on Zorro slots on both motherboard and daughter card, I have never had an Amiga 3000 but what I Understand Amiga 3000 will not boot without daughter card.
It does and i had it in many many times when attempting boots
@@ChrisEdwardsRestoration
Okay, I thought it might have been that, I don't know what else you can try,
She is already back with her owner
@@ChrisEdwardsRestoration
Okay, no worries
does A3000 clone boards exist? ask for donations so you can have some made,for boards like that.
thats mr Hertell who does those swaps. i can do the Acill 4000 boards as they are pre populated with logic and sockets, just transfer your chips and ports over
scope cs on the rom?
Excellent! That would point to the components that connect to /CS.
chip select worked. i did much more work off camera to keep the episoides down to roughly 30 min a pop, i recorded 6.7TB of footage over 64 hours.
It's too much for me to watch it all. Have you been able to test all custom chips? If they are Ok, you could have the hardest to get parts for a ReAmiga 3000.
Lol just saw I'm about 3 hours late with this comment.
No shame in throwing in the towel, you sure tried your damnedest to repair it, some boards can drive you insane.
Don't think you missed anything at all and it would probably end up being something so stupid you wouldn't even think of it, been there seen that.
Rehab is for quitters
lol what is Dr Chris doing - looks highly sus
in what aspect..?
@@ChrisEdwardsRestoration he must be referring to the miniature figurine version of Dr Chris
@@ChrisEdwardsRestoration with his back facing the camera
ahh yeah he gave up on me too
