A "bus" in TARGET 3001! is a collection (pool) of all signals which appear in a circuit. Buses are distinguished in schematics graphically e.g. as addresses bus [A0…A15], data bus [D0…D7], control bus [Clk, Res, etc.]. You can connect every "signal" to each bus and get it out again later. When you start a signal wire from a bus, a list of all signals is displayed to choose from.
