I agree with the high speed communication. A USB port would be ideal, esp. if
it could also connect multiple RCX in a chain to make a larger bot. Then you
could use the USB for comms between RCXs and the RCX ir for comm with other
bots/computer, proximity detection, etc...

| (...) An ideal solution would be an RCX that included the Harris PRISM chip-set. These chips allow you to get various data speeds between 1Mbps and 11Mbps depending on options chosen. Typical range is 100-300 ft indoors and 1000-3000+ feet outdoors (...) (25 years ago, 17-Aug-99, to lugnet.robotics)
