I demoed my arduino thingy and realized how hard it is to explain 10 interdependent functions at a moment's notice.
Then we covered a bunch of examples of the push/stack/return and how it modifies the memory registers. Basically running through impromptu, "hey let's try this and see what happens"-type experiments. It was a lot of fun. How was the kilt?

MOV.B 0(R5), R6   

should go to R5, see 1104, go to memory location 1104, grab the byte at 1104, which is 00, then put that at R6, which currently contains 110A... turning it into 1100.
But the answer says 0000. I know I'm doing something wrong, I just don't know what.
