Configure three logic gates to match target W for all eight combinations of inputs A, B, and C. There are 22 circuits. G1 combines A and B, G2 combines G1 and C, and G3 combines G2 and A.
Select a gate with W/S, choose AND, OR, or XOR with A/D, and press RETURN to test all eight rows. AND outputs 1 when both inputs are 1; OR when at least one is 1; XOR when exactly one is 1.
Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.
Wires and sockets connect the gates, and visible 0/1 signals travel through each of the three stages. Sounds and marks record each row's result. Wait until testing finishes before pressing again.
The table on the right reads A, B, C, W, NOW. W is the target and NOW is your circuit's output. A star marks a match; X marks a mismatch. MATCHED counts matching rows.
