Hello,

Check this out : http://www.arcaderetrogaming.com/2.html
BTW, I am the designer of this board.
What I can tell is that it is more powerfull than a Minimig (faster bootup, faster SD-Card access, more memory, multi-core selection) and it is cheaper.

Regards,

Frederic

Hi Frederic,

Compliments on your design :) Do you have juicy specs to publish, or is it still too early to disclose further info?

Are the cores and hardware design an open platform?

Cheers!
Edwin

Hello,

I can release some characteristics:
- 12-bit RGB output
- S-Video ouput
- Stereo output
- 2 x DB-9 joystick connectors
- 2 x PS/2 connectors
- 1 million or 1.5 million gate FPGA
- 16 or 32 MB SDRAM
- 4-bit SD-Card mode
- 5V DC input
- Multi-core selection
- JTAG connector
Last but not least : cheaper and smaller than a Minimig.
Concerning the openess, we will certainly release the FPGA pinout and some VHDL modules so everybody can make their own VHDL design.

Regards,

Frederic

Hi Frederic,

Which platforms is it capable of running? What kind of price?

Hi,

That looks nice.

Let me know if it needs a case for it. I could design something for it. Have a look here:

www.loriano.pwp.blueyonder.co.uk

again great work!

Looks nice. I guess a bigger fpga opens up for integrating the 68000 cpu in the chip. Pity about the exclusion of the serial port though.

From the picture it looks like there is no M68000 onboard

Yes. I would think that leaving out the 68k would cut costs a bit too and increase flexibility. I want to see the minimig core running on this one!

Another thing that isn't immediately obvious is how the SD card slot is hooked up or what microcontroller it uses. Does it have the same microcontroller performance bottleneck as the existing minimig design?

No performance bottleneck, I expect to have 10MB/s on 4-bit SDIO.

Frederic

Hello,

for the moment, I put the C64. You can see by yourself :
http://www.youtube.com/watch?v=jo33eNhapkE
http://www.youtube.com/watch?v=o9GNE3VK75w
http://www.youtube.com/watch?v=YvKJHkEA3-w

30% of the FPGA is used (full C64 + VIC1541).
I cannot tell the price yet but, it will be cheaper than the Minimig.

Regards,

Frederic
