I think about Terminal-BASIC based programmable calculator, like MK-90

I am planning to use Arduino DUE, TFT screen schield and custom matrix keyboard of40-64 keys.
Does anybody know, if this shield is compatible with arduino DUE?

Actually, I'v just tried it on my risk. Screen itself works well with UTFT library with the same C++ code as for Arduino MEGA, but SD card doesn't. On MEGA both screen and SD card slot do work. And what about slot for a small FLASH chip?

I'v started a dedicated campanion project of Terminal-BASIC programmable calculator at

SD card slot on this shield can't be used on DUE by default, because DUE hasn't SPI pins on its left dual socket of digital I/O.
