| (...) I measured the RCX consumes about 33mA in ROM or Lego Firmware, around 26.5mA under LegOS (due to the sleep instruction in the idle task), and it will use 0.034mA when turned off. No matter how long you sleep in your task, the RCX will consume (...) (25 years ago, 26-Mar-00, to lugnet.robotics.rcx.legos)
