Default FPGA Replay Board
Hello to Mike J and Yaqube.

I know you guys are probably swamped in work and out shopping mega-pacs of fireworks already, but could you see if you could publish images or youtube clips of the Replay board itself and when operating and maybe also with the 060 daughterboard installed ?

We would be glued to the monitors, even at 23:59:59 at 31.12.2010 if you do this....screw the fireworks :-D


Merry X-Mas and a hapyp new year!!!

Frankly speaking there is not much to show right now. Everything has been delayed slightly.

I should get the new revision of the board shortly after Mike has verified the design. The daughter board should be ready in January.

In the meantime Tobias has managed to implement missing bitfield instructions. It has increased the core size to 75% of the FPGA.

We are still working on fixing minor problems. Finally we've got the RNC Copy Lock games to work.

Cheers for the info. Sounds like things are just about done with th exception of a few morer tweaks.

Just out of interest, will/can the AGA core be ported to the C-One?

The current Minimig AGA core needs circa 25K logic cells. The Cyclone-III on the C-One extender has 24.6K LCs but some more are required for another CPU core acting as ARM MCU replacement.
Actually it's very hard to use more than 95% of the FPGA due to limited routing resources. It's hard to tell for sure but with clever coding it might be possible.

@yaqube, 75% of the Spartan-3E 1200 ..?

75% is a lot, and makes me wonder about the space for the AGA core etc..

75% is taken by: Minimig AGA core (with 24-bit scandoubler) + SDRAM DDR memory controller + TG68.C (V0.40) + dual CPU caches + 16-bit DMA AHI sound card module + 128 channel embeded logic analyzer

I would like to know how much it would cost to add an Amiga floppy drive controller to this board. Its a strange request, I know, but I'm curious. I still need to read/write Amiga floppies.

The Kryoflux USB floppy controller might be just what you're looking for, of course there's the small question of amiga drivers.

http://www.kryoflux.com/

Alternatively it may be possible to connect a floppy drive up to some spare I/O lines and run it through the FPGA.

I'm interested in the Kryoflux, but it costs $172 CAD$. Great with a PC with USB, but not really an add-on for an FPGA based Amiga.

@Yacube can i use my new unused ceramic PGA 060 rev 6 (71E41J) on your daughter board ?

Maybe it's possible to overclock the cpu in the future this cpu can run 80 mhz easy..

Or maybe in a few years it will be much, much faster take a look at this up coming FPGA technology:
