Thanks for keeping me updated! Are you using a public core or your own? Have you made a test series for it and verified all of the opcodes and status bits?
The next step should be a vga core to emulate a terminal. There is a GREAT project out there that I tried on my Spartan 3 kit. It is a complete System09 on the board. VGA, PS2, monitor, etc. If you want I can try to find the site.
It ran out of the box on the Digilent board.
