(...) either. some people like the e1 better because it has more flexible timer and counter lines. but the a1 has a simpler bootstrap sequence and is less likely to have compatibility problems with the host computer.

Hello: First - thanks for all the good information that we were able to find on the handyboard web page and on the associated ftp site. My son and I have decided that we would like to build the handyboard rather than buy one ready-built. We have no (...) (28 years ago, 19-Dec-96, to lugnet.robotics.handyboard)

(...) I'm assuming you mean the motor LED's and that they stay on and nothing shows up on the LCD. Sounds like you didn't disconnect the battery and accidently shorted it. Probably lost the contents of the RAM. Try reloading the Pcode. hope it works (...) (28 years ago, 19-Dec-96, to lugnet.robotics.handyboard)

Is there anyone out there that would have some IC routines that might get me started writing my own. Something for controling two motors, bump sensors, and IR sensors. Really anything that will give me a general idea of the direction I want to go (...) (28 years ago, 18-Dec-96, to lugnet.robotics.handyboard)

Didn't someone (William Lim?) write a paper about BALI, a small version of JAVA, that could be used for small mobile robots?
