I'm thinking the same thing.... I'd like to learn some Verilog or VHDL.

I'm considering the Nexsys2 board from these folk:
http://www.digilentinc.com/

It has more RAM than the minimig, and a larger FPGA for experimenting.

It looks very like the Xilinx Spartan3e board. Note it only has 8 bit colour (better than 3 bit though). There are some notes on www.fpgaarcade.com on how to modify these boards to get 12 bit output, and a test program (with source) you can modify for your board which will output a test pattern.

Ahh.... good references to have.

The Nexsys2 has 16mb sdram, 16mb of flash, and a config flash.  I'm guessing the 1.2 million gate version could hold the TG68 core ported over from the Altera DE1/2. Put the kickstart in the flash rom. the fpga core in the config rom, and good to go. They even have a little board with the memory card interface for the ADFs.

Of course, all that's easy to say  ;-)
