hi all  first an hello

i have the 7421/05 with  no jtag points on the main board its different layout to similar models as the pics on the wiki show regarding  jtag
ie http://www.t-hack.com/forum/index.php?topic=380.0

so i have sanded down the smp found the jtag points as per pic  as it shows on the wiki my point is this

i have traced tdi  tck and tms has any  one else played with this as im struggling to find tdo?

aye  im hoping to reduce amount of wiring to smp for others tbh ive got it down to 2 points to poss wire on chip none would be good but looking like possible 2 unless some 1 else has found tdo?

I have the same board as ezzie and i am a noob at these boxs, is there any info n thses boards apart from what ezzie has found.

i havent had a lot of time to further investigate but will be looking further into this shortly as it is not as straightforward as it seems
some of the points on the smp that are used for jtag seem to be grounded so when i get a bit more time i will look into it a bit more
