A microcontroller based solution such as Andreas one (http://www.inchlab.com
)would perhaps be more suitable for your application.
A thing that would be helpful for this kind of heavy configuration would be
an "IO-processor" consisting of a microcontroller linked to RCX through IR
messages. This would provide a lot of "virtual sensors"...
To stay in a non-programmable world, you can perhaps implement a counter
(4017) that switches between sensors at each toggle of active/passive sensor
mode - and use a battery pack for this power hog !
Michael Gasperi mux is more or less based on this configuration.

| Philippe, Nice work. I ordered a few parts and am going to try it out. Now if I could figure out how to multiplex 4 sensors to a single input an be able to monitor them individually. The goal is crossing sensors on the front and rear to give true (...) (25 years ago, 23-Apr-01, to lugnet.robotics)
