Tried SDcard read and write program and SDcard seems to work!
The info program i found to read info from this second TFT LCD shields gave this info:

The LCD Demo Statistics program did not work with this TFT shield!
As i did not yet tested the touch possibilities with my first shield, i wanted to test it with both shields.Found a "paint program" TFT Colorbar for the TFT shield.
This program TFT Colorbar program displays colored blocks and a drawing area on the screen. It reacted to touching the screen but not in a correct way. X and Y seemed swapped.
Found on line 35 landscape=0 and changed this to landscape=1 After this the program worked (on both TCT screens) !
