Hi Will, I'm assuming that you're using IC 2.81 on an IBM PC? One possible cause is that since IC 2.81 is a DOS program, the serial communication routines for old IC is flakey under a DOS box under Windows. Please run with the window in full-screen (...)

It seems to be a bit difficult to find those L293D motor drivers here in Finland. But types B and E are available. What is the difference between types? Is it OK to use type B with HB? I don't have the data sheets available, so helpful information (...) (29 years ago, 12-Mar-96, to lugnet.robotics.handyboard)
