This is normal. Here is an excerpt from the testing notes:
The Handy Board will display the message ``Press START to test
knob...'' on its LCD screen. Press the START button, and the screen
will show the message ``Turn knob; STOP to end -> xxx,'' where xxx is
the current value of the knob. Turn the knob and the value should vary
with a minimum of zero and a maximum of 255.
Press the STOP button, and the Handy Board will show the message
``Press START to test analog ins.'' Press the button, and the display
will then show a series of seven numbers. They should all be in the
range of 250 to 255.
When you plug in a sensor, the sensor port will work properly.

You may be using a motor that is too powerful for the Handy Board, or
perhaps your battery is not fully charged.

| Hello, all. I've just gotten my handyboard from Gleason Research, and I am totally ecstatic to have these awesome capabilities physically possible at last. Well, anyway, I have had a few problems. First of all, IC (I have the freeware version) is (...) (27 years ago, 1-Oct-97, to lugnet.robotics.handyboard)
