When the bridge of the Klingon D7 class ship was shown all the controls were touch-screen. Ships of that era (Star Trek [the original series]) had dials and switches. It is not likely that it was upgraded, because by the time the technology was availablethe ship would be very far from Klingon space. Also D7 class ships were armed with only phaser banks, there were no photon torpedos. Also a cloaked ship cannot fire any weapon. OOOPSS!!
