Ehm, bist du sicher das du ein cabke brauchst ?
"Device1 supports a combined Parallel Port + Cable III type interface to
allow programming of an external FPGA target. This function can also be
redirected to act as a programmer of Device2 offering a seemless
connection to XilinxTM ImpactTM and ChipscopeTM tools. The external JTAG
interface will be capable of running at 3.3V, 2.5V and 1.8V programming
levels. It will also be 5V tolerant and we expect capable of handling 5V
JTAG chains (only 3.3V drive on signal levels)"
"Tarfessock1 has two Spartan-3E FPGAs.
Device1 is a Xilinx Spartan-3E XC3S250E-4FTG256C FPGA and contains the
Cardbus, Programming, A/D, DAC, Charge Pump and serial interfaces and is
generally not intended as a customer development device. However
customers may use Device1 as a development target if they so wish.
Device2 is a Xilinx Spartan-3E XC3S1200E-4FGG400C FPGA and is the main
development device for customers. It is also possible for us to fit a
XC3S1600-4FGG400C as an alternative part.

Das steht in der Tarfessock1 beschreibung, also ist im device1 Parallel
Port + Cable III mitintegriert (+ external port damit man für andere
borads nutzen kann).
