First of all THANKS. I hope this works out.
It looks like you have a JTAG connector on there - please keep that.
The CPLD you had on the last board, XC9572XL is a bit long in the tooth,
perhaps? Would you expect to use that one again, or a newer chip?
An area with place to mount, say, a 40 pin header (2x20) or the like, on
one edge of the board, with a set of places where one could jumper those
pins to a set of I/O pins of the CPLD/FPGA would be really cool.
A spot where one could mount an Arduino compatible shield - again with
no actual connections, but a place where one could jumper them to some
I/O pins on the CPLD/FPGA might be really cool. (e.g., using the CPLD
to run an SPI bus connection to a shield).
In short, ways that folks could take your basic board and make it
possible to do other things with it could increase the value of the
But, these are JUST SUGGESTIONS / THOUGHTS I am throwing out. I would
not be at all disappointed if such things were not done.
You might consider KiCAD as an alternative to Eagle. It works pretty
