Hi. I see there is a library called portfolio.tpu for the Atari Portfolio. As I understand it, the PC-3000 and PC-3100 are the 'second generation' of the portfolio. Does anyone know if portfolio.tpu works with the PC-3100, or if there is an updated version for the PC-3100? Thanks (I just bought a PC-3100 a week ago, so sorry if the question has already been asked) James
