(...) I don't think that would work very well, as the lights have a rather low resistance, lower than a pressed touch sensor ((URL) as a purist you can use the cybermaster sensors to multiplex three inputs ((URL) Jürgen Stuber <stuber@loria.fr> (...) (21 years ago, 9-Sep-03, to lugnet.robotics.rcx)

(...) LEGO purists use LEGO light bricks as resistors. I created potentiometer bricks, where the resistance is variable for each brick. Two stacks of 4 potentiometer bricks can be seen to the left of the RCX. In this case each stack puts the (...) (21 years ago, 9-Sep-03, to lugnet.robotics.rcx)

You can use four touch sensors per input port on the RCX. The Cybermaster touch sensors have resistors in parallel, and this is how the Cybermaster knows which implement is attached to the tracked robot. It uses its sensor input as a temperature (...)

(...) OK, I've looked at your wish list and have the following comments with respect to how I see the pbForth implementation of DCC. 1. How important is it to have more than one port with DCC capabilities. The reason I'm asking is that it "would be (...)

(...) Doh! I forgot about Odd parity and the USB tower. I will see about fixing that little problem. Is your quad speed boot loader source significantly different from Kekoa's fastdl.s (with the parity disabling code removed)? I'd like to see it if (...)
