If so, then I believe (with no physical ND-100 available to me anymore) the answer is "no". The K bit (one-bit accumulator) is as far as I can tell only affected by the BOP instructions. The 'extra' bit which I used to describe how Carry works is in one way a construct (used to show _why_ the C bit ends up as it does), but in another way it probably exists physically in the ALU: Even though it's only implictly used by SUB it can be manipulated explictly by the ROP instructions after all, using the AD1 and CLD modifiers.
