JTAG target board circuit design

thepancake,

Thanks for the reply. I will take a look at the schematic review

worksheets. Too bad there isn't one specifically for the max7000 family. The application note that I referred to (app. brief 145) was specifically for the max7000 and said to pull up the TCK but that was when using the Bitblaster cable, so maybe it operates differently than the USBblaster. I did find some documentation that expressed how sensitive the TCK is to reflections. If this is the case, maybe a socket type chip can't be programmed with the USBblaster cable.
