[i]While the TV camera was upside-down in the MESA, the pictures were also upside-down. When Armstrong removed the camera to plant it on the lunar surface, the pictures would be the right way up again. A simple technique was employed to invert the images during the scan-conversion process on the Earth. This involved modifying the scan-converter by installing a toggle switch on its front panel. The switch was connected to the deflection coils of the Vidicon camera by means of a relay, which then inverted the picture by the simple expedient of reversing the vertical scans. Richard Holl, who was a Bendix Field Engineering Corporation engineer responsible for television ground support, helped design and implement the inverter switch.[/i]
