Dr. Martin, I am planning to build another robot with TCOMP on it, specifically the TCOMP 3.5, can I still use IC for this board? You can find TCOMP address here: (URL) in advance. joema (26 years ago, 23-Oct-98, to lugnet.robotics.handyboard)

I can not get the sensors to respond correctly, for instance if I do analog(0) the value of the sensor marked 7 on the hb is returned.

Sounds like a lot of it is still up and running if you can download. I'd suggest going through the assembly instructions and performing the tests at the end of each section. You should, thereby, be able to isolate smaller areas that may be fried and (...) (26 years ago, 22-Oct-98, to lugnet.robotics.handyboard)

I didn't look that closely at your program but I have included a routine to read the analog ports that I know works. After assembling and loading the program, you make two c function calls: powerup_ad(); and read_ad(i); where i is the analog port (...) (26 years ago, 22-Oct-98, to lugnet.robotics.handyboard)
