Take a look at the schematics, which are linked from the top page of the Handy Board web site. The info you are looking for is in the CPU / memory schematic. For the DC Motor outputs, the board uses a separate output latch---not the timer outputs. (...) (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

AAAARRRGGGHHHHHH!! After the pain of relearning assembler and getting interrupt routines to work, it seems my assumption of the availability of TOC 2 & 3 is incorrect. I need 2 (wanted 4) pulse trains to go out. According to the diagrams Fred (...) (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

(...) Thanks for the tip. I got a hold of the book and read some of it. :) I was wondering if sending pulses to the motor would cause "choppy" rotation....or does it occur so fast that inertia effects make it "smooth". Also, with an h-bridge, is it (...) (30 years ago, 25-Mar-96, to lugnet.robotics.handyboard)

(...) I'm doing signal conditioning for pan/tilt and (ultimately) drive/steer signals from an RC receiver and driving servos with the processed signals. All power for the servos is external, so all I need is signals through the Handyboard. -mike * (...) (30 years ago, 25-Mar-96, to lugnet.robotics.handyboard)
