Ok, so a couple of weeks ago, I ordered the Xecuter coolrunner along with the xecuter official xilinx lpt jtag cable, which came with the power cable to use with ck3. I plug my ck3 lite in, connect the power cable from there to the coolrunner, turn the ck3 on, and both of the LED's on the coolrunner light up, and the chip identifies correctly in impact. The problem starts however, when I try to program the chip with the Jasper JED. It fails and says the IDECODE was wrong or something. I figured since I am using outdated hardware, the voltage might not be correct, so I was gonna hook it up to my box with the 3v3 and GND connections then try my luck. I will let you guys know if that succeeds, and let me know if my theory is correct. Best regards,

to flash with that cable you need to use 2 GND, one from CK3 and other from LPT.
Connect two GNDs on CPLD chip and IMPACT can flash, TX coolrunner orCPLD form ebay etc.
I used GliGli's schematic ;)

sorry for bad english
