Hi Salpi, if you hold down the 'start' button while switching on your Handy Board, the code defined in "main" that is in Handy's memory at that time, will not run. You can then download a new program to your Handy Board and run it. Success, Marc (...) (25 years ago, 2-Jun-99, to lugnet.robotics.handyboard)
