This thread details the technical aspects of the data recovery itself, if you want to learn the background story, visit https://www.kennettclass...ata-from-lunar-mission/ The short story is we received an ASCII papterape proported to have had been created containing a "data dump" from the 1969 American Apollo lunar landing. Teh tape was generated using a Honeywell DDP-516 minicomputer located at a NASA facility in White Sands, New Mexico. Apparently an operator made a personal backup of the lunar landing data (?) ![]() Three tapes were supplied in addition to the Lunar Landing tape. The other's are labeled "ABCT" and "8X MEDIC" Click image for larger view.
Using the DSI NC-2400 reader/punch I set it up to pull in the tapes, I created a dump file that appears to be accurate, at least a good first try. 21KB. Stand by for more! Reply |

The archiving is complete. You can download these tapes and read them into simH or other Honeywell DDP 300/500/ class emulator. Note that the binary tapes available from the link above are only viewable in a hex editor or directly downloaded into simH or actual Honeywell DDP system.
