Richard, Thanks for the help. I finally got the board to accept the pcode. I acquired a PS/2 mouse to free up my COM1 port. I used the HBDL.exe program that came with the board. After several unsuccessfully attempts to program the board, for some (...) (26 years ago, 15-Dec-98, to lugnet.robotics.handyboard)

Hi people! I'd like to know two things: 1) Can I use the 68hc11a8 instead of the 68hc11a1 in the Handyboard, without recompiling Interactive C? 2) What's the minimum hardware to run Interactive C?

I built two more Handyboards and I've noticed something odd. When I download a program with a main() function, and reset the board, main() does not get executed. I thought it was supposed to.

Make sure that your com port 2 is actually wired to the motherboard I've heard a lot of stories with com ports not working because they forgot to connect the ribbon cable. Check that first. Try booting ito dos and use the DL.exe instead of the HBDL (...) (26 years ago, 15-Dec-98, to lugnet.robotics.handyboard)

In reference to your question about the motor with encoders.

eric, i don't have a definitive answer, but here are two things: 1.
