MiniMig with AGA

Well an Amiga with AGA, that comes in a nice case, with AGA support, 2 meg chip (expandable) and 8 meg fast over 95% compatibility, a couple of times faster than a standard Amiga 1200 (for Elite Frontier) and under $300AUS would be on my wish list.
 
The minimig here in Australia seems overpriced for an OCS Amiga as no one here sells locally and even with our strong dollar at the moment I can't justify forking this out for. However I can justify an AGA Amiga
 
I know people say you can run Amiga Forever etc which I already do, but I don't like the idea of running an Amiga on a Windows System.
 
I look forward to developments and hopefully you'll have the boards ready for sale for the Christmas rush. Good luck with your venture I hope you do well, remember only "Nixon could go to China" and now only the "Amiga can make a come back from China"
 
** if I look on ebay I get around $270 for a minimig in a case from the USA, postage though is quoted as $137.00 there abouts which over half the cost of the item, pity someone doesn't import them and sell them locally in Australia.

This explains why my mailbox is now full. Sorry if you have mailed me and I have not replied, I'll try and get around to everybody.

I'm in China at the moment and working hard to finish the RevB layout. There are about 30 connections left to make, but it's pretty much done.

This has a few fixes over the RevA board. The main difference is the connectors are all moved to one side (not the rs232 debug) and it includes composite/svhs option on the main board.

It should go to manufacture Monday, and I hope they can make them in time before I leave...

That's awesome Mike!

What are the specs of the production boards in terms of RAM?

Is it 64meg for the dev prototypes and 32meg for production boards?

Would it be possibe to buy a board with 64meg?

Obviously more RAM is better... especially if we ever go towards Capcom/Neo Geo emulation as those ROMS are pretty huge!

[mikej]

All boards have 64MB, I made a mistake on the schematic before - I can't count.

:-) By the way Mike, shall I sketch a case for this new board, it might be on the lines of the Minimig case I designed two years ago:

That's basically what an '030 is. It's an '020 with higher possible clock rates, and as mentioned above, the onboard caches, and MMU in the non-EC versions.

 
So then from a softcore or emualtion point of view, an 030 would be pretty pointless.   I very fast 020 would be enough.
 
030 only any good for real hardware

The 020 has no data cache. Also the 030 supports a burst mode which the 020 doesn't. Should increase the throughput a lot. But I don't know how these things behave in a fpga reimplementation.

We forgive you about the "can not count part"

Wheeehiii 64MB SSSssooo sweet.. ;-)
I want one FPGAARCADE but you already know that !!!

I doubt softcores are going to implement any cache anyway. They just rely on the brute execution power, faster memory etc.

WOW!!! I've only just come across this Minimig today! Can't believe you kept it from me for so long

I too would want an AGA version. I do miss my A1200.

By the way for those wanting a portable Amiga, have you come across this before:

http://pandorapress.net/

I've been following the progress and it looks really promising, They have a version of UAE up and running on it as you can see from the videos. I have a Wiz myself which also has UAE and runs A500 stuff great.

As for the Minimig.. I would love to run this in my living room as a retro A1200 and having it as a divx player. Is there no way you could have the SD cards memory mapped as chip/fast ram? I know it would be slow in comparison to dimms etc, but surely its faster than 20yr old real Amiga memory? and this way you can expand it as much as the SD card can hold.

I long for the day i can play AB3D2TKG full speed on a real Amiga..

The Natami team's 68050 softcore has caches.  They are bigger than the original '030's caches also though possibly less than that of an '060.  And before you play the "vaporware" card they are just finishing up the bitfield instructions.

And before you play the "vaporware" card they are just finishing up the bitfield instructions.

Mr Gunnar von Boehn say 25 Feb 2010 10:01 that he started with  bitfield instructions.
"To complete it we now started work on adding support for the Bitfield instructions to our core."

[SamuraiCrow]

I meant that they are just finishing up the instruction set with bitfield instructions.  Not just finishing up the bitfield instructions as I said.  Oops.

Also, the latest info indicates that they are going to try to have bigger caches than the '060 also.

Can we please keep to something that is going to happen during this decade (or at all)?

@MikeJ

What FPGA does it use? [edit]Nevermind, I found the answer... Spartan 3E[/edit]

And is the estimated pricing still the same?

Yeah cuz FPGA tech will never be able to run a Amiga software...

Oh wait?!  O_o
