@wtaysom Thanks, I'm often surprised by how powerful the motherboard programming is (the logic panel as you call it), that was kind of an accident. Back in the early days, each motherboard contained a little snippet of Clojure code but I noticed that a lot of them were simple if/them clauses and when they weren't you could simplify them to be so by making the other logic physical, if you know what I mean? For instance instead of writing code to detect a recent button press in the Simon game by having a Clojure variable to keep track of the last time a button was pressed, I just created a physical thingamajig that is in a certain state for a while after each button press. So if each motherboard can just be simple if/then statements with or/and/not conditions, then it can be represented by a simple graph. Even things I thought couldn't be simplified this way like a while loop turned out to be possible, the "player" circuit is a physical while loop for instance.
