I think I've seen those XESS boards before.  Don't remember where, maybe 
advertised in circuit cellar or nuts and volts.  Their website seems 
pretty goofy and for the most part doesn't work for me in firefox, so 
I'm not sure.

I've enjoyed learning about digital logic and FPGAs.  There is a fair 
bit to know.  I've found verilog pretty straight forward to pickup. 
Once I get a better handle on it, I'll probably try my hand at VHDL as well.

The Spartan 3E board I bought has a bunch of connectors, and built-in 
support chips.

I've been working on a USB external amiga floppy drive controller for 
the PC.  Read and create emulator .ADF images from floppies using a 
standard PC 3.5" drive.  I first used a Parallax microcontroller, and 
then recently switched to an FPGA solution.  Both work now.
