My board is not widely available - Altium NanoBoard 2, the Virtex 4
version. My code is all open source soon to be published on a web site,
so you are more than welcome to port it to whatever.
The synthesizer used is Altium, but most of the project is portable
Verilog

What I have right now is a functional //e Enhanced with CF interface,
MMC/SD emulating a floppy (with .NIB images) and best of all real
slots that work with an actual Disk ][ controller and a 5" floppy.

However this runs at a regular 1 MHz. I will not attempt to move the
whole thing to a warp speed, but I want to make a simple device with
just a CPU and a CF disk and run it at full speed.

The current version (like my old FPGApple and the Altera DE1 version)
run at 28 MHz and only use one cycle out of 28 for the true speed.
Virtex has plently of internal block RAM and is happy to run at pretty 
high clock speeds. I want to make an Apple 50 to 100 times faster than
the real 2e.
Definitely not for playing Pacman :)
