The first page is headed: "GAP: Assemble Revision 116 of AGC Program LUMINARY by NASA 2021112-071, 19:09 Aug. 11 1969, (Main)." The second page notes: "This LGC program is intended for use in the LM during the manned lunar landing mission or any subset thereof. The details of implementation are specified in Report R-567, as amended…This program is referred to as LUMINARY 1B." Annotated "116" on the edge. In very good to fine condition, with one of the nylon binder posts broken and some creasing and minor paper loss to edges of some pages. Revision 116 was manufactured and sent to Raytheon on August 12, 1969—the day after this printout was made—as the official LUMINARY 1B release, and it would fly on Apollo 12 in December.
