You can select the project over Input 0 and 1 (e.g. 01 for the seven segment encoder) and then have the 6 remaining pins for the project
Set Input 0 and 1 to LOW. Input 2 is the Data In Pin, Input 3 is the Shift Register Clock and Input 4 the Ooutput Latch
Set Input 0 and 1 to HIGH and then you can use Input 5 to 7 for the multiplexer Inputs 2 to 4 are for the Inputs of the ALU the Output is connected to Output 1
Set the Inputs like for the ALU, but now ise Inputs 2 to 4 for the first number and Inputs 5 to 7 for the second. Outputs 1 to 4 are the Resulting number
Set Input 0 to LOW and Input 1 to HIGH and then use Inputs 3 - 6 for the number input (MSB first)
