So it wasn't electrical, and it wasn't programming.

Whenever I've seen a Digital Sidecar go flaky, it has always been traceable to one of two things. Either something put battery voltage on one of the pins, or there was metallic debris present.

Debris is almost always from careless drilling or filing. In both of the cases I saw where it was an accidental connection to battery, the root cause was someone working on the robot structure and letting wires flop around at random. So you're right, it wasn't electrical, and it wasn't programming. It was mechanical. Do we have a new scapegoat?
