And you need to buy a bigger FPGA and design a new board. ;-)

I thought the big advantage of this effort is that you don't have to build [color=ff0000]any[/color] board, you can use a stock Altera or Xilinx dev board. Granted, more stuff needs to be done to the Xilinx board - more bits to the RGB, and an SD card interface. But it still seems to make more financial sense than a custom board, unless you have the skills & tools to do it yourself.

BTW, Futurlec has a miniboard with a SD card reader interfaced by SPI.

Why not an open source one from opencores.org or some other? Probably familiarity and competance at using it :-D It hardly matters as long as the chip is capable of whatever its being asked to do which doesn't sound like a lot.

There is an open source Z80 compatible core on opencores.org.

I kinda like the idea of the Z80, I had some experience with it myself, back in the Elder Days. ;-)
