Yeap last device I designed than needed LCD graphics and buttons, I used a
Palm Pilot. They have cheap throwaway ones, (IIRC they were us$25 in Qty. of
100) they had 1Mb ram, rs-232 interface, 160 X 160 pixel gray scale LCD. Not
sure how well any LCD would do in the sun if left out.

The device never went ahead, as we could not find any "reasonably" priced
LCD's that could survive the AU outback sun lol (they all seemed to fade and
have sections stuck on after 6 months in the sun (continuous) just to do an
extended lifetime test). A CRT version would have been too heavy and bulky.


Regards,

Kat.
