ok ill do
-
Can you make it more compact and add more instructions to save?
-
cuz it calculates binary
-
you can program it with RAM cuz it can allow to do things like: if (blah) then (blah) or if not (blah) then (blah) or if (blah) and (blah) then (blah) just in binary
-
of course it can add and subtract till it hits higher than 15 which is a overflow and it will redirect to carry output
-
its composed of 4 full adders, 4 XOR gates to subtract, and 4 OR gates to check if answer is 0
-
i see its 4 bit, as i see the 4 gate groups (registers?), so it is easy to upgrade too!
-
this is easy to program too! just use switches and you are set!

nice pfp of giorno and golden experience requiem
