That's the thing, there are so many options around these days - and some 
of them just a flash in the pan - that you're far better off finding a 
board that already has _everything_ you need built in rather than opting 
for the cheapest core and adding to it.

Of course there are also several purpose-built microcomputer emulation 
boards, such as C-One, OCM, Minimig, Mist, Replay, MCC, Suska, TC64 and 
probably more I'm not aware of. The advantage of the TerASIC DE boards 
is that there are already quite a few cores available and a decent user 
base, so they're likely to be supported in future.

And if it's Coco3FPGA or Roger Taylor's version you're specifically 
interested in, know that they'll be easier to port to other Altera 
platforms (as opposed to Xilinx). Of course it can be done, but the 
clocking and on-chip memory, and the tools of course, differ and can in 
_some_ circumstances cause issues when porting.
