Your post #119 - it appears that some magic occurred to change that triangle to a sine wave.

Post #120 - the switch appears to be connected to the negative voltage input, thus validating the negative output. The problem is that 9 volts is more positive than 6, so the output should be positive.

q9

answer: "MSB would not change state"
But I don't really understand, if the upper AND gate stucks high, consequently the OR gate is also always high, so it means, that MSB inputs also always high, which in turn is equal to the state, when they are connected to the battery directly. Both MSB and LSB receive a synchronous clock pulse. So summing all that it must be that both bits change their state at once and behave in an equal manner, both change state every pulse. Possibly I have merely misunderstood smth. but just in case describe my doubts.
