2. PDP-8 assembly language (7 points) What is the two's complement 12-bit representation of negative 17? a. (13 points) The following PDP-8 machine language program loads the contents of address 0x400 into the accumulator, subtracts 17 from it, and stores it back to address 0x400. Use address 0x711 to store the address 0x400. Fill in the blanks in the binary. See last page for PDP-8 opcodes. Note that all numbers on the PDP-8 programming card are in octal, while numbers in the question below are either hexadecimal (if prefixed by 0x) or binary (if made up of zeroes and ones). Each blank is one binary digit. b.
