It was about 100 bucks from Amigakit, sent off my motherboard and 3640 to them and it's been running awesomely ever since, well minus the funky OS side things I've done to it ;)

   Sounds like you got lucky, I've read too many posts about waiting and waiting for items to come back from repair from them.  $100 is certainly a reasonable fee to re-cap both the motherboard and the 3640 though.

   I am glad that it worked out for you.

If you don't want software emulation, and if you don't want FPGA reimplementations, then perhaps this is more for you:

Jens's Amiga Reloaded project:

I've been hoping that Jens would come out with his AGA project for some time now. He supposedly reverse engineered most of the AGa chipset. In this case he's going to use existing stock of old chips. Hopefully, a full replacement motherboard modernized.

There is a guy that calls himself maccaps on ebay i think it is:

http://www.ebay.com/itm/Amiga-A4000-Re-Cap-Service-/181795613932?pt=LH_DefaultDomain_0&hash=item2a53dcecec

he also has a web page i believe.

I have a c64reloaded and its a neet board.
The amiga board jens is doing infortunately needs alot of dongles and is a 1200 style board. i want a 4k board with onboard 060 preferrably without all the bottle necks of the 1200.
Jens has supposedly bought up the world supply of aga chips i hear ;/

That's what the article seemed to imply about Jens and the AGA supply. Where did you see the additional details on the board Jens is working on? I'd suspect he'd want to use boards he's designed to fill in the gaps. I agree, I'd love to see a more modern AGA board myself.

Have you used the guy on eBay to redo any boards yourself?

I dont recall where i saw the details on jens stuff, sorry.
As for caps, i do my own and have been for 20 years now, i have recapped many a board for others,but i hate doing it,you almost have to put a gun to my head lol.  the only thing worse those is changing 72pin simm sockets :)

I just suggested the maccaps guy as a solution, i dont know much about his work, hopefuly he isnt doing silly stuff like using tantalums and ceramics in place of electrolytics in the power circuits.

The a1200 is simpler and the only bottle neck is the cpu slot, which if you're using a bus board with it's own cpu is not much of a problem. Although the problem then becomes the form factor.

The a4000 would be much more complex and therefore expensive and in comparison the improvements possible would be minor.

I'd much rather see a standard form factor board using an off the shelf I/O controller with an upgraded AGA and a cpu that outperforms the fastest 060. I think we have a way to go before that is possible though.

Myself, I would love to see an ATX form factor board with AGA, 040/060 socket, and Zorro slots.  Using a standard ATX power supply too.   KS 3.9 on a large single EEPROM, on-board Indivison, USB would also be awesome.  No daughter cards or things hanging off other chips - just a nice and clean layout.

One can dream...

Kickstart should be in flash & I'm not convinced about Zorro. It's too slow and the cards are too expensive. I can see that someone with a stack of Zorro cards might see it as a positive, but I'd rather have m.2 and PCIe slots.

Using modern ram so that you can dma from disk and have the cpu fetching while aga is saturating the "chip" bus. If you reimplement AGA then it can also run the blitter at the same time and you may as well support ~4gb of chip ram. i.e. stick 4gb of ram in it and map ram in the areas that aren't needed for I/o cards.

Use a socket and you could start with an FPGA for CPU+AGA and switch to an ASIC later.

Here: " http://maccaps.com/MacCaps/Repair_Service.html ".

Some good reviews and positive feedback on that site. Looks to be good and reliable. Will probably send my A2000 to him for cleaning/capping soon.
