1. Use Logisim or another graphical circuit editor to draw a circuit diagram for this boolean expression taking inputs A, B, C, and D:
        OR(AND(A,B),AND(NOT(A),XOR(C,D)))
   (Feel free to use logic gates; you can use bare transistors if you want!)
   

   • Give me a screenshot named "1.png".
   • List all the values of A, B, C, and D that will make this expression evaluate to true, in a plain text file named "1.txt".

2. Use NetRun to write some assembly code (for any machine) that uses a loop to add up the numbers from 0 to 5, inclusive, and returns this sum. Run the code, and verify the answer is 15.
   

   • Copy the code out as a plain text file named "2.asm".
