---------------------------------------------
soldering JTAG signals (this is only needed when you cannot find a connector)
---------------------------------------------

access the back side of the PCB
follow the signals from the EXT connector to the via holes near the SMC socket:

  ??? TDI TMS
   o   o   o
 o   o   o
??? TDO TCK

you can use the big testpads for power/ground:
	T1 - VCC
	T7 - GNC

you can use needles to make a connection if you care about warranty.
you can also clear the 4 via's by scratching a bit and solder some wires.
tip: mark the wires if you wish to close up GP32

---------------------------------------------
connecting JTAG signals to slow parallel port
---------------------------------------------

parallel port
You can use a simple voltage divider that outputs 3.3V
Let's calculate... (I'm not good at this either)

Drawing up to 4mA from the parallel port is pretty safe.
So I recommend a minimum RTotal of 2 KOhms.

GND ---[R1]---*---[R2]--- 5V
              |
             3.3V

UT=5, U1=3.3, RT=R1+R2, I=UT/RT, R1*I=U1
R2=R1/0.66-R1 => R2=2.2/0.66-2.2=1.1333333333333333333333333333333 => R2=1.2 (choose R1, calculate & round R2)
U1=R1*I => U1=2.2*I=3.2352941176470588235294117647059 => 3.3
(x1=through R1, x2=through R2, xT=total, U=voltage, R=resistance in KOhm's, I=current)
Blah blah, so...

According to pinout in http://jtag-arm9.sourceforge.net/circuit.txt (should be Wiggler compatible)

+---[2K2]---+---[1K2]--- PAR. PIN 4
|           |
|          TCK to GP32

|          TMS to GP32

+---[2K2]---+---[1K2]--- PAR. PIN 5
|           |
|          TDI to GP32
|
+----------------------- PAR. PIN 18..25 (GND)

TDO from GP32 --[100]--- PAR. PIN 11

The TDO resistor should make it more safer. Maybe another resistor to ground is even better.
Pull-up inputs for example are still 5V ya know.
                                                        _                _
Hmm... resistors increase raise/fall time of signals. _/ \_ instead of _| |_  :(
It's cheap and slow anyways. Serial output on a parallel port (LOL)
