There is quite interesting board with 400k Spartan FPGA designed to be Amiga hardware emulator

http://www.ebay.co.uk/itm/MiniMig-FPGA-Motherboard-Amiga-500-600-Emulator-/160808157843#ht_4215wt_840

I guess my endgame for when ASICalypse comes will be staying with capable retro gaming machine and having it halfpriced thanks to bitcoins Smiley


How much hashing power could I squeeze from XC3S400-4PQ208C?
Will 2Mb of onboard memory will be sufficient?
Do I just dump core with hardcoded input data through JTAG?
Is there any streamlined process to prepare cores, preferably with FPGA chips to preselect from?


Thanks

None, unless you plan on developing your own bitstreams. And then, when you develop your own bitstream not much, because this is an old Spartan-3, not the newer Spartan-6 that is used by almost everyone else.

Great educational toy though. XC3S400 is supported by the free Xilinx ISE Webpack.

Edit: I take back the "great" from the "educational toy" above. I took $127.15 as a total cost, but this is just postage. So the better description would be "great ripoff on an educational toy".

Yeah, pretty much anything involving the word "Amiga" commands a big price premium these days...

Quad XC6SLX150 Board: 860 MHash/s or so.

Oh, I wouldn't buy it from ebay, it's waaay overpriced there.  I think I might be able to get it with the casing (sold separately of course) for around 200-210e. That said, I wish I had other nostalgia hobby sometimes, SNES seems so much cheaper Wink

To be honest I don't want to make thousands out of it, just to be able to substantialy lower the cost of the board by mining while not playing Syndicate or UFO Wink

I remember reading somewhere on the forum about Spartan 3 500k based core utilizing 60-odd percent of the die. There was no Mh/s info though. I guess it's because number is not impressive at all Sad

No new Amiga for me than. Thanks for clarification Wink
