| (...) which pin were you using as ground reference? Maybe redo your test using pin 15 of the Maxim as ground. First check the Maxim is getting good power and ground (pin 15 is ground, pin 16 is +5). Then re-check the voltages on pin 2 (should be +9 (...)

| The PWR light isn't really an indicator of power. It's actually hooked up to the 6811's serial transmit line, so it's supposed to flash when the 6811 is talking serial. the BATT light should always blink when the board is first switched on. It also (...) (28 years ago, 4-Jun-96, to lugnet.robotics.handyboard)

Any voltage outside of the 0 to 5 v range is hazardous, unless it is current-limited to a few milliamps. (...) Are you sure about this? On page 49 of my (...)

If you remove this (by cutting the trace between the sensor input pin and the 47K resistor pack), then the analog inputs are pretty high impedence, like a meg or so. You should get the "M68HC11 (...)
