Fixed the accumulator update logic in all the PDP-10 half-word self-mode instructions, and started work on EXCH, BLT, and MOVE instructions (the BLT is a real odd-ball, and SIMH does some very strange things with the accumulator used by BLT, which we do NOT attempt to replicate; the strangeness is most noticeable when the accumulator is part of the range being transferred)
