| | | Does Anyone know how to modify the handy board so that when the battery is disconnected the memory on the board is not lost? In short I want the HB to have nonvolatile memory so that I do not have to reload the pcode in bootstrap mode every time the (...) (26 years ago, 8-Mar-99, to lugnet.robotics.handyboard)
