Never knew of this. Wild what vendors did. Dr. Chris, thank you for another great Amiga history share!

Wish to see it working flawlessly again. Keep up the great work.

One more on the saved shelf. Such a great conversion as well.

Hi Chris, Nice to see you again with a another Amiga. I work on a IBM 5150 and waiting for parts now. Succes with this Amiga. Greetings from Steven from the Netherlands

[@WhiteHareGames]

Exactly the tower I've had for many many years with my Mediator 4000 system. Wonderful tower. I really wish I hadn't ditched the original desktop case and daughteboard, though, as I now have a 2nd motherboard and nothing to house it it. Good job (so far) with the fix! Don't forget two caps by the audio are the wrong way around on the silk-screen.

[@kriegermetal]

Awesome work as always, looking forward to part 2, hopefully the Mediator is in good shape. Of the (2) A4000 rescues in ~2005, this one was in a news broadcast studio in somewhere USA, so they must have had it repaired as this was doing overlay/genlock work via toaster/tbc before migrating to the tower. BTW Mediator bridge has to be in the bottom slot, and it can map video card memory into fast ram. Also great new working music/outro/end cap. 😃

oh yeah she comes around.

[@rtid7538]

That's a 'Power Tower', as in Power Computing. A re-badged Elbox 'E/BOX 4000' tower. Sorry for being pedantic. 😅 I bought the A1200 version from Power back in the day. Still have it and use it, but I suspect I need to consider a new PSU solution after 25+ years! Great video, Chris, as always.

12:55 - Nice! I never knew you were a player! :) 27:28 - Every Amiga is different; Back in '90, I tried to put 2 A2000s together to get one of them to work, but had to give up on it when we moved: never did finish that project and needed to sell stuff off while out of work for a long time...

Cool video. I have never seen an Elbox 4000 tower before. But, where was the mediator board? I have complete confidence by the conclusion of this series you will have it running like it just came off the Commodore assembly line.

[@CrystallisedEntertainment]

27:38 - I want to say for the record that this phenomenon isn't just exclusive to Amigas... I recently upgraded the RAM on my Acorn RiscPC from 40MB to 96MB; and what should've been a 5 minute job turned into a nearly 2 HOUR job because it suddenly decided it would fail the boot self-tests! I knew the RAM stick that I left was good and couldn't figure out why it was now failing to post... I have got the machine working again with the new RAM stick but what I did shouldn't have upset it! 🙃

good im not alone then!

Great stuff Dr Chris 👍🏻 Where are you getting the chips from? Especially the DAC? Just sent over my Rev C (Rev 2) for repair to a U.K KZbinr SHG Retro for repair. What were the differences between the Rev B and Rev C? Not the DCR version. Cheers 🍻

[@ChrisEdwardsRestoration]

ebay on the Dac, then Kavanoz had a line on them so i got some from him also. the B was the main one Varta/Nicad rechargable leak, C was the last one produced by commodore, not the CR but the C has everything SMD, no sockets
