Parallel JTAG Adapter Schematic

Thomas J
Hi.
I would like to know if anyone know where to find the schematic of the
Parallel JTAG Wiggler which comes with the mini2440?
It's because I would like to find out if it's possible to use this wiggler
(as I already have it) to program the Xilinx Spartan-3E Sample pack:
