Dangerous Prototypes pcb drawer (I got a code and used it to ask for a bus blaster pcb). If came taped to the inside of the envelope with a business card - no problems in transport at all.
I also left out the diode for the target voltage connection... Usually if I have to connect to a device with higher voltages than the jtag programmer can handle I inline a zener on the flylead, or I make a voltage translator so that I can connect directly to a lower voltage port. It's probably a good idea to put a zener on the programmer to prevent accidental damage, but I didn't have one so I just left it out.
I was expecting to use a different jtag programmer to setup the board, but since the chip they used (FTDI2232) has multiple ports it wasn't needed. The documentation for the bus blaster is around here and from that there is an nice explanation of how to self program the device here.
page in particular to be very helpful... They to do a functional jtag test against a logic sniffer (also Dangerous Prototypes... and also something I have on hand (on the top here) - very very useful - small simple quick and dirty and efficient tool - I highly recommend it). Chain scan worked perfectly the first time... yay... I'll test it more completely when I get some time later, but if it passes these tests then it ought to work without problems. I'll check the signal quality on a scope later but 68 ohms seems to be fine for the new part of the design.
Dangerous Prototypes makes the neatest stuff, and I love the openness of their development... hopefully one day I will have something worthy to contribute...
