please read instructions before use

alu neutral instructions:

A IN/A OUT:0=take inputted a,1=save current output and use it as a until turned back to zero

B IN/B OUT:0=take inputted b,1=save current output and use it as b until turned back to zero

ALU SELECTION:0=take gate alu as output,1=take operation alu as output

DISPLAYS:

TOP 3=the systems current a

MIDDLE 3=output

BOTTOM 3=the systems current b

gate alu instructions:

GATE SELECTION:00=A AND B,01=A OR B,10=NOT A/B,11=A XOR B

A/B IN FOR NOT:0=take a as input for NOT,1=take b as input for NOT

operation alu instructions:

OPERATION SELECTION:0=A+B,1=A-B

SAVE A:put this alus current output in register a

SAVE B:put this alus current output in register b

OUT ALU:take output from alu

OUT A:take output from register a

OUT B:take output from register b
