FYI, after seeing post #3 by jcoleman, I decided to check if the minipac I bought in April had TB support... and it does!
Granted I don't have the wiring harness for the TB, but I don't have the harness for the buttons either. Most of the connections on the board belong to a 40pin IDE cable (including the x&y axis of a TB). The only ones that don't seem to be on the IDE are 5v & grounds specifically for the axis. I'm still not quite sure why they may require their own seperate power but I'm waiting for a reply from Andy at Ultimarc.com. If you want to find out what I find out it'll most likely be posted
