R

-------------------
          BOS sel     Selects the BOS register if 1 for all stack ops, else TOS.

          Clr LB      Resets the LB, ALU, Display, and god knows what else

        --------
         Carry        Vectors to carry (also sign by way of hack)

[ Note: get carry jmp by clearing Treg, the comparing contents of Treg to Sign
reg from stack.  So kick me.]
