I'm not familiar with the Wirz board, however the board I built used the regular "motor output" of the handyboard with no modification required. The trick was to use an opto-isolator to "recover" the forward and backward logic states. That was done (...) (26 years ago, 24-Jan-99, to lugnet.robotics.handyboard)

(...) That sounds like too much voltage for the HB. I think I remember reading that the HB runs on up to 12 V max. Check the Handy Board Technical Reference. There are much better ways to run motors that require higher voltages. Try using a separate (...) (26 years ago, 24-Jan-99, to lugnet.robotics.handyboard)

Hi Folks, I was just reading the FAQ and encountered the part about the memory map. Does anyone know how the expansion board maps as it is not included in the memory map in the FAQ? Thanks, Chris Prosser (26 years ago, 23-Jan-99, to lugnet.robotics.handyboard)

Hi there, In my humble opinion, I suspect that the problem is with Interactive C.. Try a newer or older version. What version are you using, by the way ?
