I have build the board described in my book "Mobile Robots" which is a great book. I just got the board going after realizing it isn't a good idea to assume the pin outs of all 32K x 8 ram chips is standardized :) I was hoping someone could help (...)

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 think the Interactive-C overhead will prevent such fast repetition. Simple statements take about a millisecond, with printf's taking 10 msec. You'll probably have to do it in assembler, and use an .icb file. Hope this helps... -mike * (...) (29 years ago, 11-Mar-96, to lugnet.robotics.handyboard)

Hi, I've been trying to write to PD2 using the following: int write_port(int port, int value, int mask) { poke(port,(value & mask)|(peek(port) & ~mask)); } It works fine except that the fastest cycle that I can get out of PD2 is about 242 Hz.

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 (...)
