Try BG Micro, 1-800-276-2206, www.bgmicro.com/ . They have/had a quantity of used A1's for $6.95. You may need to clean/straighten the pins, but so far the ones I bought work.

I ran into the same problem. I was unable to set it with any of the utilities for the handyboard. I ended up using my mini-board and its download software to correctly set the register. I don't know why it worked. Andy hobbytec@cas.auracom.com (...) (27 years ago, 2-Apr-98, to lugnet.robotics.handyboard)

(...) This won't work, as the servo's require a one-shot, not a variable duty cycle type of pwm (like what comes from the motor drivers on the HB). ie. the width of any given pulse is not consistent, just the overall duty cycle.

My advice, don't waste your time, i spent about a year trying to figure that out and never got the config register changed to anything useful, and I also contacted motorola about 5 times and no tech person there could get it changed either.

Jaron, Does the compiler provide LCD driver for HB or you ported the code to this compiler ? -Pandit (27 years ago, 2-Apr-98, to lugnet.robotics.handyboard)
