Yes, but I believe that in most cases the CPU for a human has a few more
KB of RAM than the RCX.

| For some reason, bots are compelled to follow a single line. Whereas humans typically keep within two parallel lines when they drive. However, when they are inebriated, humans may try to emulate the bot, often with disastrous results. There exist (...) (25 years ago, 16-Nov-99, to lugnet.robotics)
