If there is ever one for the 1200 then sold. Although why only have MB's for RAM? $20NZD for 2GB DDR3.
Why not put a SODIMM/DIMM socket on the board and provide it without RAM. I have a couple of spare SIMM's here :-)
Soldered memory is more reliable and it keeps the complexity on the mass produced fpga board. There are multiple fpga boards with this style connector to choose from so it's cheaper just to buy a higher spec fpga board. More memory and features does draw more power so it's important to consider if the 1st boards will work in a 500 without upgrading the power supply. Different fpgas may require twice as much time synthesizing cores for 2 fpga boards.
Would prefer IDE/SATA connectors over an SD Card.
IDE takes high voltage by modern standards. SATA requires more expensive high speed transceivers although the cost of supporting it is falling. For now, the Amiga doesn't need much storage and an SD card is probably better than what most Amiga users use today for storage.
On the website it states initial tests faster than an 060, what speed 060 and do you have those benchmarks to share? :-)
There are no benchmarks to share as the Phoenix fpga CPU core has not booted an Amiga as far as I know. The Phoenix processor in something like a Cyclone V would probably be 100-150MHz. There is tons more memory bandwidth and plenty of logic for huge caches (32-64kB). The 68060 is superscalar which helps it but Phoenix will likely out muscle it. There is a mostly complete superscalar version of the Phoenix processor also. Each of the integer pipelines is more powerful than the pipes in the 68060 and it has the instruction fetch (from the memory bandwidth) to feed the hungry monster. It's entirely possible, if not likely, that this fpga CPU would eventually outperform the 68060 clock for clock. The Phoenix CPU has to boot AmigaOS first though.
More than 2MB chip RAM would be good too.
Adding chip memory inside the fpga is minor compared to implementing and debugging SAGA inside the fpga. The extra chip memory and AGA/SAGA gfx would only be available when using the DVI/HDMI output.
