Thanks for watching!
What an absolutely amazing job. This video of your efforts to revive the machine were outstanding and brought a tear to my eye. Well done! I'll always be a fan of the Amiga.
Thanks man!
Excellent work around for the psu. Glad you got it all working in the end.
Thanks man! Yes, I am pretty happy with the solution. A2000 power supplies go for crazy prices here.
Regarding the 68000 with the broken legs, you can cut off legs from a broken larger chip and solder those legs on to the broken ones. This will extend those legs, which with a little bending, will go in the socket perfectly. I've repaired several of the custom Amiga chips that someone butchered, this way. Also bear in mind that specific 68000 is a 16mhz chip, not the usual 8mhz one. It should work perfectly, but it will only work at 8mhz.
Good thing you saved it from the recycle facility. Nice job 👏🏼
Thanks!
Thanks for posting this. I have a dead A2000A that I really need to do more work on.
If you need any help, let me know. I am an expert now ;-)
What a shame about that 2000! But you have a working big box now… I think it’s an awesome deal after all the work and swapping of parts.
I think so too. I added a second drive and closed the huge CD gap. Looks much better now. Will post photos or short soon.
You got a good deal. Even basketcase Amigas like this one go for multiples of what you paid for this one here in the US. It was deceptive of the seller to hide what the machine was though.
Even heavily abused Amigas fetch top dollar on eBay. At least you got a good bundle of custom chips and an original case to build from.
Yep. True. I am happy with how it turned out.
Yeah, you were definitely scammed. I was an Amiga repair tech back in the day. When you opened that A2000, I saw a lot of problems. First was how the machine was just cobbled together. Whoever built that Amiga knew NOTHING about the insides of the machine. They had the screws inside the bottom of the case without screwing them into the motherboard!
Something useful for next time: in PiStorm we created a utility called "buptest", this tests communication with RAM, mostly to test the PiStorm is functioning. But it can be used as an actual low-level RAM test. The low data bus lines often break on Amiga 2000s due to the battery leak, so buptest would easily show you which lines are damaged.
Thanks man! That's good to know. I will mention that in a future video.
@@RetroWK no problem. Really you can expect four possible fail outcomes from buptest:
1. It hangs, usually a control bus line isn't working
2. The data is a bit or two off in each output, data bus error (or a whole nibble/byte off in the case of some buffer chip issues)
3. The data returned is the ROM, the PiStorm couldn't talk to the CIA for some reason
4. The data is complete random, usually an address bus (sometimes control bus) issue
@@linuxjedivideo Thanks! That is some solid info. I am sure a lot of people can use that.
Nice recovery from an absolute disgrace of a 2000 - you should report that seller to ebay.
Excellent work as always :)
Thanks! The seller thinks he has done nothing wrong. I told him he unloaded his dead parts bin on me, he says I bought a not working A2000 and that's what I got. Yeah ... Not sure if I write a bad review since I fixed it.
Nice save. I think that I would mount the exhaust fan externally so that hot air could be actively drawn out of the A2000. With anything plugged into the external ports on the rear, you need to leave some space anyway, so mounting the fan externally shouldn't cause a problem. You can put the fan grill on fan too, instead of the case.
Thanks! I am planing on putting the original power supply in soon but maybe with a silent fan. ... but that is the topic of another video!
The old powersupply fan doubled as a system fan. But I guess it's fine as long as it's not powered on 24/7 with harddrives installed. 👍
Thanks! I did not think about that. You are right. Since this is basically an A500 (which has no fan) it should be fine. I may add some stuff and I may also get to fix the real power supply.
@@daw7563 That's what I meant. If you look at the block diagram you can see that basically only some traces lead from a few of the custom chips to the bus (Zorro II, IDE) logic. I recently saw an A500 add on card that add that bus logic to an A500.
@@youtubevideos415 I think you'll find the current draw on an vanilla Amiga 2000b MB and single floppy is going to be as close to an A500 as no matter. It's only if you start adding expansions that it will change.
About that M68K, you could try soldering some hard jumper wires on them and test it, as long as the leg isn't ripped off from inside the IC package, it's completely fine
Yep. Did something similar. I put it into another socket and soldered the broken legs onto it. Works fine!
@@RetroWK Awesome, now you have another spare CPU too! Also, great video!
I think you did really well for the price you paid. This doesn't look to be too too unusual for the state of a non working A2000 sold as is. If he sold it as working and ready to use ya that's bs. I think maybe a diagrom would help as well. Do you have a 27c400 or 27c800 and a burner?
Yeah, I have to make one of those in the future ... but I think I need an adapter for the MiniPro first.
@@RetroWK I'd say if want a better idea if he did this on purpose check out his other listings. Lots of computer stuff he likely knows what's up. Random garage sale thrift store stuff he likely hasn't a clue.
He sells almost only A2000 components and machines. He knows!
@@RetroWK Yup. No reason for him to be dishonest. I think people would have paid his price knowing the psu and other things needed work. He had no reason not to say it.
I have a spare 220v Amiga PSU if you’re in need. It is working condition, but I would probably recap it on principle alone.
I acquired it from a unit I bought from PAL region and I’m in the states.
Thanks for the offer! I think can get my PSU working. I have all the parts needed now, so we will see about that. Since I am in Germany it would be cheaper to buy one of eBay (50 UROS) than ship yours to Germany (60 to 80 $). But again, thanks for offering!
@@RetroWK of course. Always happy to help the community. Shipping is always the issue when crossing the pond.
Good luck with the rest of that.
Great video, thank you for sharing. I learned a lot and hopefully can fix my A2000 too :)
Sorry, I didn’t have enough caffeine to wake me up, which is why I didn’t include any advice (I was mentally exhausted from the past week). I was going to suggest the RAM, but it looks like you checked that in the part of the video I am watching right now.. I would check underneath the A2000 for any cold soldier joints. If the machine ever overheated, it could cause soldiering joints to go bad. Also check the Agnus chip socket for any hairline fractures. People were famous for upgrading to a 1 meg Agnus chip and breaking the chip socket in the process.
Thanks! Great tips! I will check that and I will use that info in future A2000 videos!
Tolles Video, hat Spaß gemacht zu schauen. Wo wurden denn die Ersatzteile beschafft? Gerade der CPU Sockel ist irgendwie schwer zu finden. Hast Du da einen Tipp?
Die Sockel habe ich von eBay. Sind in der Tat sonst schwer zu beschaffen.
Pretty reasonable price these days and nice work 👍👍😃
Thanks!
Hello, Very good video! 185 dollars or Marks? I always wonder why or how someone selling retro electronics can do such bad packing jobs!!! YES IT was very very uncool! What was his eBay rating when you bought this? Did you write a review telling others what they did? If so, how many stars did you give them? Have you soldered on 2 legs onto that CPU to test it? Very good Video! TY!!!
Thanks! 185 Euros (what is about the same in $ right now). That guy seems to have specialized in A2000 stuff. And unloads all kinds of crap. He has a 100% rating and I am still unsure what to write. His description was "Does not turn on. Broken." I think that is very different from what I got. I soldered two legs on the CPU it worked and today it finally gave up the ghost. It was barely hanging in there.
Did you end up borrowing the Agnus from your 500? I noticed that these got swapped out. But you got a hell of a good deal. A comparable one (non-working, PCB damage) here in the states is going for $475. I certainly wouldn't complain. :)
Nice job getting it going again!
Here in Germany you can get working ones for 250 EUROS ... that is pretty much the same amount in U$ right now. So putting the 175 in perspective is Okayish, but only because all the custom chips were ok. I used the Agnus from my 500 just because I did not want to swap them back around after testing. Same AGNUS model, so all is good.
@@RetroWK That's what they were here about 10 years ago. Not so much anymore. :)
I've seen A2000 at stupid prices, I think you paid a good amount for a semi-trashed one. It has a realy nice case.
Yeah, in the end I am happy with it. It was also a lot of fun to repair and refurb it. I made a few more improvements since the video. Will post photos soon!
@@RetroWK Cool.
That looks like a white A600 mouse! Hard to find
Nope. Just an overbleached good old tank mouse 😎
I bought 286 that had PSU, Mobo, FDD, VGA and Multiio damaged. Man, people do this... It's very not cool.
I'm not sure how you were scammed? we didnt see the listing describing the condition
Well the listing is in german. Pretty much: "Does not turn on. Broken.". Which implies to me that the machine has worked before and that it is not an artificial graveyard for broken parts. Otherwise I (as a seller) would state that.
@@RetroWK Well if its sold as spare/repairs then its guaranteed it doesnt work! are you new to buying on ebay then? as 99% of folk who would see that listing would understand its broken, again not sure how you were scammed seems a bit clickbaity to me, if hed stated the item was in working condition then yes scammed or if hed send you a box of books then yes scammed but if hes sent you the item as per the description then thats not scammed thats your own fault for not reading the description and/or asking further questions if you werent sure
175 euros ain't bad imo for this... But its lucky you know how to fix
Going into this I had never fixed an A2000. I learned along the pain ;-)
i haveto give you credit ...you turned a shit deal into something good! great job!considering what you have done..i think you got a very good deal,!! nice
..
Thanks!
If you think you overpaid at €185 then please sell it to me lol!
After putting in the work it now is a really nice machine.
This a have seen before see people buy from EBay and has cracked over hole computer if it be me gonna be mad like hell
