MiniMig with AGA

[whiteb]

That's right, give them to the people that will move the 'platform' on first, then when they get the softcore(s) working correctly Mike can do a new production run of a revised board for the the general populus (eg us).

I just hope that someone like AmigaKit or ACube pick this sucker up and market it properly.

I think Revision B is more or less where Mike wants the boards.  HE already said that once these 50 work out, it will be no hassle to bang out more.

I agree that the people who are working on the core's should get the first boards made, but... WE WANT SOME TOO

My other half will probably kill me but please put me one down for me as well, as long as it under $300AUS :-)

I hope RevB is the final version in this form factor. The very first few will be prioritised for developers, that way we get more stuff to run on it.

It will only be available ready-made, it's not really possible to hand assemble. Well, you can apart from the BGA but it takes a while!
Best,
Mike

Very nice, count me in too, I assume you already noticed the pm from yesterday?

There are two 32 pin connectors at the back which contain a whole load of IO pins and 4 analogue inputs, so you can make an adapter cable. This is also for arcade game input connectors.

Hi Mike

Great job on this! I'm not sure if i've missed anything here, but wouldn't usb connectors be a good idea? Then you could connect any peripheral to it

I'll definitely be interested in one of the Rev B products.

Are there pin headers on board for parallel and serial? How about pin headers for expansion (CPU bus, etc) - although I guess that the FPGA is better for expansion internally, if there is space. I like the idea of adding an AHI compatible 16-bit audio system inside, with an internal mixer for paula audio as well.

It would be nice to have a centralised website where all these projects could be hosted and have updates - it's very hard to keep track of them all, all the tweaks, the softcores, etc.

Good luck with the testing and production builds!

Ever since I shorted out my a1200 in 1999, I regret throwing it out.   I'm really dumb that I threw out my 1230 50mhz card too....I do not know why.  

Anyway, this project sound amazing!!

Mikej, Please add me as well.

@hattig

Toccata emulation may help for that. Anyway I'd like to see 020 support before. And Cirrus||Virge emulation after 020 support :-)

Will you also be selling bare boards to those who wish to assemble one themselves, like some of the MiniMig boards were sold, or just completely assembled boards?

Do you have a reflow oven ?  The FPGA is BGA (Ball Grid), you cannot just take a fine pitch soldering iron to it.

Then again, people are fixing their video cards, when Dry joints appear on them under the BGA chips, plonk them in a Toaster Oven.

With all those pins and such, is there any possibility of adding a real Amiga floppy to the mix?  
I have to admit, I kind of like putting a disk in the drive to load a game.  Hearing that evil sound as the floppy performs the head-killing dance of copy protection... Even flipping though my collection of disks brings a nice retro feeling.. :-)

What's wrong with working the BGA on with a rework station? They're just US$99.

These guys rock! I just bought a USB PIC programmer from them.

As I understand it re-flow is the way to go for BGA... to make clean precise solder connections. The other way with an SMD iron could get messy...

The board is equipped with a 24-bit stereo audio DAC. Upgrading Paula to 16 bit and writing suitable AHI driver won't be a big problem. I'm also thinking about more sophisticated solution.

There is still a lot of unused memory bandwidth which can be used for implementation of an advanced flicker-fixer or graphics board (although implementation of CL/S3 chips seems to be impossible).

Both the AHI and P96 require at least 020 CPU and this is the next design object.

This thing keeps getting better guys

I'm definitelly interested on the project and i could buy one unit once everything is set for an standard user.

However i would like to know what is going to implement at the end this Rev B board.

020 or 030 code? Hig res modes? Gfx and audio card emulation?
Will it be faster than a 030 /50?

Maybe this is asking too much for now... XD
But it would be good to know what are we exactly aiming to.
