Breadboard Computer Documentation

Components Needed:

1. 74LS181 (4-bit ALU)
2. 74LS86 (quad 2-input XOR gate for flag calculations)
3. Breadboard
4. Jumper Wires

Steps:

1. Place the 74LS181 on the Breadboard
   • Insert the ALU IC into the breadboard
2. Connect Power and Ground
   • Connect pin 16 to the +5V power rail
   • Connect pin 8 to the ground rail
3. Connect ALU Inputs to Data Bus
   • Connect the A and B inputs of the 74LS181 to the data bus
4. Connect Control Inputs
   • Connect the control inputs (S0-S3, M, CN4) to the control logic outputs
5. Connect ALU Outputs
   • Connect the outputs (F0-F3) to the data bus
6. Implement Flag Calculations
   • Use the 74LS86 to calculate flags (e.g., zero, carry) and connect these outputs to the control logic
