As stated in the past, Jamey has left me with an h2200 that has JTAG
leads hanging out the side - or at least, that connector. I have yet to
get JTAG to work, however. Most combinations of pins I've tried seem to
hang the device, while other combinations just read crap as the chip IDCODE.

I would not suggest using a parallel port cable at this point. I'm not
sure how well the HAMCOP will handle the parallel port voltages. You
would be wise to choose your resistor values very carefully!

Hopefully...
