Hi Can you power the RCX from a Wall Wart while the batteries are in it ? The reason for this question is I find I spend a lot of time programming / down loading and testing while sitting at the computer before letting loose my creation - all this (...) (25 years ago, 2-Sep-99, to lugnet.robotics)

(...) down (...) Hi, Yes - should be OK - power connector disconnects the batteries when an external PSU plugged in (assuming the plug fits the RCX properly!). I guess there is a small risk of the firmware getting erased when plugging in/out the (...) (25 years ago, 2-Sep-99, to lugnet.robotics)

Not necessarily so, there is some residual capacity. I have replaced batteries in the past without loosing firmware or programs by flipping out the old, and inserting the new within a couple of seconds. (25 years ago, 2-Sep-99, to lugnet.robotics)
