I don't have a handy board but am considering getting one. I like what I have seen so far! I have searched the FAQ and the mail list archives but can't find the answer to my question. How much of the 32k does Interactive C take up? OR MORE TO THE (...) (26 years ago, 21-Jul-98, to lugnet.robotics.handyboard)

The paper referred to is at ftp://cherupakha.med...Martin.pdf My personal advise is that you simply *get started*. hook up your motors and start driving your robot around. see what it can do, how it moves. then connect sensors and gain an intuition (...)

Hello, I have developed a machine code programming system for programming the handyboard. It is similar to the Buffalo routines on the Motorolla 68HC11 chips. It allows a relatively simple way of machine code interaction to the display. The program (...) (26 years ago, 21-Jul-98, to lugnet.robotics.handyboard)
