(...) Just buy a USB to Serial adaptor and use your Serial Tower if you can't find a USB Tower for sale anywhere. They're not very expensive and work fine. Many new desktop PC's done have serial ports these days. Dom (17 years ago, 23-Jan-08, to lugnet.robotics.rcx.legos)

(...) If your IR tower still functions, and it's just a matter of not having a serial port, the simplest solution would be to just buy an adapter that will allow you to hook up a serial device to a USB port.

(...) Confirmed. The arrows and grey button share a common resistor ladder and only one can be detected. But the orange "on" button has an independant circuitry and can be used separately. See keypad schematics in the HDK. Philo (17 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)

Can someone confirm that the front panel buttons on the NXT are wired in such a way that it does not work to press two of them at once? Not too surprising, I suppose, just as early computer keyboards were pre-decoded to signal which single key was (...) (17 years ago, 21-Jan-08, to lugnet.robotics.nxt, FTX)
