Additionally, if you had bricks for all these types of functions, you could
build logic systems with the bricks directly from schematics or circut
diagrams...
Imagine being able to say something like, "signal the RCX if touch sensor 1
and 2 are touched together, *or* if light sensor 1 is not on" ...
The benefit to being able to do this is that it is all done in "brickware" and
all sitting on only ***ONE*** RCX sensor input!!!
You would need one AND brick, one OR brick and one NOT brick (a NOT brick
might be hard to do, would it need it's own power supply?)
This would be a great help in conserving RCX inputs...

| Hi, What about LEGO AND-OR matrices, like in PALs. We could use one stub to indicate each wire crossing, and use metallic 1x1 plates to "burn" contacts. The plates would be rather large though... and the electronics complicated... :-( Just a thought (...) (25 years ago, 30-Dec-99, to lugnet.robotics)
