Hpsap, there are numerous switches in the SA-2, SA-3, and SA-4. Do these actually do anything that applies to the sim? If so, what do they do? Also, in the SA-5, there are two idnetical-looking panels/indicators above the speed officer's main screen and the Fire control officer's main screen. What do they do? (they are the ones that display the Lissajous curve during AS3 tracking)
