Rather than write some emulation software, I'd like to see if I can
implement some simpler CPU designs in FPGA.
I see various development kits out there with various capabilities
(I/O memory, displays, etc.).
Is there any particular kit that stands heads and shoulders above the
others? Is there a preference between Xilinx and Altera?
I use them both, but for some reason I prefer Xilinx. It may be that
they are slightly easier to get via digikey. They are often horseraced
by customers of mine (which is fun to watch).
I don't think you can go wrong with this for $89

and if you want to get motivated, check this out

Let me know when you boot the scelbi basic interpreter on a flat screen
vga :-)
I use several open source verilog interpreters to test code before I put
it in a device - cver and iverilog (er, ah, http://www.icarus.com/eda/verilog
and http://www.pragmatic-c.com/gpl-cver). Work for me. Modelsim on win32
is also really nice but not free.
