How portable are these computer clone implementations to other FPGA chips? The one used in Replay is marked "not suitable for new designs" asfair. So newer Xilinx chips will be needed sooner or later.

When they've got an Atari Falcon clone I'll be interested. :)


Ha ha, don't hold your breath! :)

The Amiga implementation shows that Motorola 68030 alike is doable. But the DSP, Motorola 56001 is a more uncertain component. I don't think the other chips would pose a big challenge.

So anyone that want to try this computer should deal with the Motorola 56001 mainly.

I've just been reading through the 56K data sheet, doesn't look too bad actually.

Its  a great and usable Motorola design, Falcon has proven it by doing way more then it was possible on 030 Amigas. It was planned for A3000+ sadly never out, and would fit Amiga way more then Xena.

If you manage to recreate the Falcon I'll be a very happy chappy indeed. :)

The Suska team are working toward Falcon compatibility it seems. Might be portable to the FPGA-Replay board, depending on what goes in the FPGA, and what goes on the board outside.

... The work on the Falcon chipset continue smoothely. You can see the current status in he section Progress.

... Furthermore Suska-III-N, a new hardware based on a Cyclone-III has been developed. It is a platform well suited for the realization of a Falcon. ...

Well now this is amazing! So in theory, if they can pull off the DSP for the Falcon, then a developer should be able to acess the DSP from the Amiga side, right?

All we'd need at that point is a driver or library to use it, then yes.

Delfina library? That card featured a 56001. I loved the delfina - should have kept it instead of selling it off. The 56k was used for quite some effects or to offload mp3 decoding. Unfortunately the RAM was very little (at least) on the lite board.

A straight question: When can i buy the fpga arcade board and use it as an amiga out of the box with no problems with line codes, complicated configs, out of the blue errors etc, just ready to use my 3.1, 3.5 & 3.9 hdf & adf games - demos, this year perhaps? thanks.
Great work mikej, keep up.

This year, absolutely - and maybe by the end of this month.  There is not much left to do at this point.  The final I/O stuff is being done and there were a few quirks with the AGA emulation that were being corrected.  It's running demanding AGA demos and such already.  So, all of the difficult work has been done.

Awe inspiring work from all those involved and especially to Mike for pushing the dream in his own time, out of his own pocket, for so very long.

A very big thank you to all involved!
