\nIf you look at the oscilloscope, you can see the fiducial marks in their proper position before and after the sync pulse. \u00a0If you look at the lower right part of the screen, you will see the notation (200us). \u00a0That is the amount of time per division. \u00a0If you count the divisions to the next sync pulse, you will see that it exactly matches the number for a single scan line below. \u00a0The voltage scale is correct as well except that the drawing below is wrong. \u00a0The signal is 1 volt, not five volts. \u00a0We have confirmation that 1 volt is the correct number from the audio tapes where the engineers recorded the voltage levels on the tape. \u00a0It is these kinds of discrepancies that we have had to research and overcome. \u00a0We have reached that magic milestone. \u00a0We now have to put those lines together into an image and we are working that now. \u00a0However, the two critical questions that were in everyones mind when we started this have been answered. \u00a0Are the tapes good? \u00a0Yes. \u00a0Can the drive be brought back to operational status? Yes. \u00a0
\nWe are at a crossroads here and I will put together a formal report and seek input on where to go from here. \u00a0As a result of our work we have found a few things that were not in the documentation that effects which way we go forward from here. \u00a0Our original plan for digitizing the images is no longer tenable and we are doing a near term work around for the image milestone.<\/p>\n","protected":false},"excerpt":{"rendered":"
The first image you see here is the explanation from the original documentation showing what a single line of lunar orbiter video looks like. \u00a0The second, is the machine fully locked up and reproducing the correct structure. \u00a0The image is inverted as it gets flipped with a jumper select on the board that we just … <\/p>\n
