Complete unused tablet of Apollo Guidance Computer coding forms, 14 x 10, consisting of 50 sheets headed: "Instrumentation Laboratory, Massachusetts Institute of Technology, YUL System Program Sheet." The gridded sheet has columns numbered 1-80 for "Card Type," "Card Number," "Spacing," "Location," "Operation," "Address," and "Remarks." The assembler for the AGC code was called "YUL," so named by Hugh Blair-Smith to commemorate the unmet Christmastime delivery date of a prototype guidance computer in 1959. The system used an IBM key punch machine to encode cards based on these program sheets. In fine condition. From the Don Eyles Apollo Computer Collection.
