Ok, I just looked it up. Is this the correct board?

Awesome stuff. In the long run this will make the Minimig even more accessible and functional, which is great stuff!

Cool.  You have mentioned that this is the board you would like to port to from the DE-2.  Have you already done this?  Do you have a DE-1 to port it to?

Yes i have it done. But I am not satisfied yet.
I think i have a bug into the Floppycontroller.
If I have fix it I will release all the Source Code to.

I have found no program for the AMIGA that use CHK or MOVEP Instructions.


Some demos are using MOVEP as it allows you to implement blazingly fast blitter-C2P. I'm also using it for that purpose at this very moment. It's a bit of a pain though, as one needs to implement a different codepath for 060.

@Belial6:
Or you could use: http://www.xess.com/prod035.php3

Which have 2,5 times logic array of XC3S400. Should be enough for Minimig + MC68000. Builtin PS/2 port, VGA, RAM.
MMC interface, Sound etc.. can be added with some very simple circuit to the prototyping header.

The board you pointed to is over twice as expensive as the DE-1 board.  No doubt it is a great board, and offers greater flexibility, but my interest was in getting TobiFlex and Dennis on a single platform that could be a realistic board for end users to purchase.

TobiFlex has already ported from the presumably more powerful DE-2 board to the DE-1 board with that in mind.

It doesnt have enough bits going to the VGA port to do Amiga gfx.

Sorry if this is a dupe but myprevious comment seems to have disapearred.


The DE1 board looks very cool, but I do have a few concerns.

1) The USB "blaster" port sounds like it's only an uplink to a host computer for programming the FPGA, not for using keyboards/mice/digital cameras/memory sticks/etc. on the DE1 system.

2) Sounds like there's only 1 PS/2 port for EITHER keyboard OR mouse, not both

3) The PS/2 port is off the side instead of along the back with the other connectors.

Maybe all this can be compensated for with something added on one of the IDE looking expansion headers.

And a question, is this thing a standard form-factor such as Mini-ITX to easily fit some case, or is it an oddball format that requires hacking a case? I'm OK with hacking a case, but it'd be awfully convenient if it just fit a standard one.

You could always cut a board to allow screwing a smaller board  into it. And then attach the larger board to the case.

If the VGA port is insufficient, there's always the possibility to add to the expansion header instead.

Xilinx have Linux development enviroment. And license is alright.

1) I don't think that it is even worth worrying about USB at this time.  In the future great, but today, it is not a concern.

2) I would leave the PS/2 port issue to TobiFlex.  He says he has already ported the code to the DE-1, so I would assume that he has a keyboard/mouse solution.

3) The MiniMig 1.0/1.1 is also a non-standard board, so we have not lost anything.

Really it comes down to the fact that Dennis and TobyFlex have actually produced something.  We can debate what we think would make a perfect design, but the DE-1 is cheap and available.  It also has at least one person who has proven himself by actually delivering something behind it, and it already runs the MiniMig.  I would rather have a working MiniMig in a DE-1 format than a hundred great ideas that are not being produced.

Where can I donate? Dennis page doesn't have a paypal button and neither does the T68 page.

I'm sure you get your motivation from your love of the amiga, the technical challenge, satisfaction of mastering the bits'n'bytes and soldering, and our appreciation.

But I notice that you need FPGA boards, can we help? If 10 people gave $20 you'd both have those developer boards.

Give us a paypal button, and the ones who only can help out with some $$ will! :)

BTW, my wishlist for minimig features is a mile long. But most of all, I want someone to get it made in china - soon! ;)
