If you want to figure it out the hard (or easy) way, try this.

MISO will have to go to an input on the parallel port (10,11,12,etc.)

All you have to look for is the clock, data, and reset lines, providing they did not make a "loopback" pin to detect their own dongle. After you figure that out, connect the input until it works.

Noting the similarity to the Altera JTAG ByteBlaster dongle, you may wind up with similar connections.
