Ok, the code for the basic simulator is now available at:

If you have a Digilent S3 board then you can download the "bit" or "mcs"
files to program it directly.

I haven't yet documented the external switch wiring, but if you run it
as is you can use the onboard switches for Reset, Start and Stop.

Have fun!
