I have PCBs for a Xilinx model 3 parallel compatible cable with some
improvements:
Schmitt triggers on all I/O - especially important on TCLK if you have a long
parallel cable.
HC (not HCT) parts and VIO clamp so it will work reliably with 2.5V JTAG
If anyone wants one I will mail them to them for free...
