I fought this business late last year, and had to modify my stepper and PWM controller boards to work with a PCI par port board. The timings on ALL EPP ports vary from chip manufacturer to manufacturer. The Microsoft spec for the IEEE-1284 are VERY loose, and open to interpretation.

I stripped them down to the bare minimum, used those horrible IDC punch-down terminals because they are $60 cheaper than 2-part pluggable screw terminal blocks, etc. If you mean just an FPGA on a board with some .1" headers, I'm not really planning any such product right now. I COULD leave out most of the terminal blocks now that the new version has .1" headers in parallel with most of them.
