While Ive kept a rough eye on them, Ive never really been particularly interested in the fpga based amiga clones, but after recent storms here that resulted in roof damage directly above my a1200 and water leaking into it Ive been giving thought as to how Id replace it.

After the problems I had getting ahold of a decent, good value a1200 + accelerator the (potential) accesibility of an fpga based amiga has started to appeal to me.

Could anyone give me a brief overview of the FPGA Arcade and minimig please? What sort of performance cpu performance is available? Also, Im led to believe that chipram can be beyond 2 meg for both? Being that Im interested in making games for ecs/aga this is of interest to me. I assume that some ram chipram bottlenecks are remvoed too and that 64bit reads are "fixed" because of this now? (not all aga machines shipped with fast enough ram to work stabily/reliably if I recall correctly?)

Is there any chance of incompatibilty between one fpga machine with more than 2meg chip
and another assuming software is written to address beyond 2 meg? Also, is UAE with more than 2 meg chip suitable for developing for these systems?

If Im not mistaken, there's currently only minimig available to buy, but fpga arcade isnt too far away? There's also a Minimig ARM based expansion if Im not mistaken?

Thanks in advance.

p.s. Im only really interested in ecs/aga which is why Ive excluded Natami. Im sure it'll be a nice machine, but amithlon is my choice for a powerful 68k/os3.x machine. SAGA is sort of redundant for my interests, so Natami is probably a bit overkill for me.

p.p.s. I appologize if there's a lack of clairty. 5.30am and Ive not slept yet

No more waiting for FPGA Arcade Replay boards.  At least not to order one.  It may take MikeJ a few more days/weeks to finish assembling the batch of 48 that he just produced, but he has asked that people email him if they want to purchase one.  The price (IIRC) is 229 euros without composite & S-Video output and 249 euros with it included.

MikeJ hand assembles the through hole solder components on the pre-assembled boards and then tests each one before he sends them out, so this takes a little bit of time to do.  I am sure he will step in and correct any mistakes I have made in this reply to your questions.

Last weekend I had MikeJ's personal FPGA Arcade Replay board (now mine, as he sold it to me) at the AmiWest 2011 Show and many people got a chance to sit down and play some games with it.  Seems Dune II was the game of choice to try out.  I was so busy with other things during the show, I forgot to get out my Amiga joysticks and hook them up to the Replay board, so the people playing with it were limited to games that use a mouse.

It is a great little system, but what I like most about it is the inventor and his willingness to listen and provide feedback to potential customers frequently, and his obvious hardware talent coupled with his foresight to provide an expansion connector that he has already designed a daughter card for with a 68060 socket, USB ports, Ethernet and more RAM.  MikeJ is a wizard and has got me thinking about selling many of my Classic Amiga systems (not all) and replacing them with the Replay board.  It has almost as much expansion possibilities at the not yet released Natami, so I would highly suggest that you get yourself a FPGA Arcade Replay board, or continue to wait for the Natami system.

Edit:  I think MikeJ is considering a much larger number of boards for his next batch of FPGA Arcade Replay boards, if enough people show interest in buying one, so if you can't get one of these first 48 boards, it should not be too long a wait to get one from the next batch (maybe a couple of months).

@fishy_fiz
Here's how I see the fpga boards...

MiniMig = Amiga 500 with massively overclocked 68000
fpgaArcade = Amiga 1200 with 030@50MHz or 060 accelerator
Natami = Amiga 4000 with 060 accelerator

An fpga Clone-A from Individual Computers could make a surprise appearance with who knows what specs. The Natami will be fully AGA backward compatible so even if you don't use the new SAGA features, they won't hurt compatibility. It should have a FPU, the best RTG (chunky) support, 3D at some point, and the most expandability but at a significantly higher price.

I am a huge fan of the FPGA Arcade Replay board, but I am puzzled why so many people forget to include the C-one that can also run the MiniMig core (not sure if it needs additional hardware or not), or the Chameleon and few mention the MCC16, when discussions about FPGA based systems that can run AmigaOS1.0 to 3.1.

MiniMig was the first, so it gets remembered, but the FPGA Arcade Replay & Natami seem to get the most attention and the rest are fogotten, or overlooked.

Let's not forget the possibility that the Clone-A may show up some day as well, as Jens has spent a ton of time on it and with his track record of making ideas into real hardware, I would be surprised if he did not put all of that prior effort into a product some day. (I see that you did mention the Clone-A)

Fpga Amigas need to be supported with updates after they come out. That is why I favor the ones that are created by Amiga enthusiast or companies that have a history of supporting the Amiga and have open specifications and documentation so others can provide support too. I think that the MiniMig, fpgaArcade, Natami and Clone A all look promising in this regard although the fpgaArcade will probably kill the MiniMig for the low end market as it's a much better base Amiga system for the price. The fpgaArcade and Natami don't compete directly as one is low end and the other high end. It would be nice if they could cooperate more on open standards which would make me support them both even more. There is room for the Clone A with a good design for the price as many Individual Computer products are. It would probably take some market share from the fpgaArcade and Natami though.

FPGA Arcade has already hit the market.

For very limited definitions of "hit the market". There's something like 5-6 boards out there now. Last update from Mike was that the rest of the first batch of ca 50 won't be available until mid November. Most or all of those are likely spoken for by those of us that have already e-mailed him, so general availability for people who want to order it is likely still a couple of months away when his next production run is ready.

And I agree on FPGA Arcade being a A1200 replacement. Maybe it can work as a A3000 / A4000 too? (minus expansion ports)

Depends what you're looking for, I suppose. With the 68060+ethernet daughterboard, it'll already be more powerful and flexible than most A3000/A4000 setups unless you're willing to spend a lot of money pushing old unreliable expansion cards into an A3000 or A4000.

@Darrin. What happened to those benchmarks you said you were going to do? Did i miss your results you might have put up?

Which ones?  I've been so busy lately that I've hardly been home.  I was away for 5 solid weeks, just had a week off where I haven't even switched on a miggie and I'm off to West Texas again tomorrow for 3 and a half weeks.  After that I fly to the UK for 10 days (so I should get a chance to call in at AmigaKit), fly back to the USA and hopefully see my wife for the first time in 3 months as she's been down in Australia, have 4 days with her and then head off on another business trip.

Keep reminding me and I'll get around to it.  

I actually stopped doing the testing on the different software because I've been expecting a new FPGA Arcade core update and I need a CDTV remote for the Chameleon64.
