Thick original printout of the assembly listing for the Apollo Guidance Computer program called "Aurora 12," approximately 790 pages, November 10, 1966, held within a contemporary 15.25˝ x 11.5˝ x 4˝ binder, marked on the front: "Aurora, 10/10/66," and on the edge, "Aurora Rev 12." The listing is headed "473423A YUL SYSTEM FOR BLK2: REVISION 12 OF PROGRAM AURORA BY DAP GROUP." In fine condition, with general wear.

According to the Virtual AGC Project, which scanned this document for archival purposes, this listing is distinguished by the fact that it is the last AGC software that retains a full suite of self-test software, and is thus indispensable for validating software and hardware simulations of the guidance computer. It also employs unique flavor of the AGC programming language: although it is a Block 2 program for a Block 2 computer, the language version precedes its final form as used in later software.
