Uncommon official unbound NASA manual entitled "Apollo Lunar Surface Experiments Package Systems Handbook (ALSEP 4)," approximately 135 pages, 8 x 10.5, dated August 1, 1970, with distribution list stamped on the front cover. The highly detailed handbook covers the structural, thermal control, electrical power, command, and telemetry subsystems of ALSEP 4, replete with fold-out schematics and diagrams of subsystem components. Experiments described include the Passive Seismic Experiment (PSE), Active Seismic Experiment (ASE), Suprathermal Ion Detector Experiment (SIDE), Cold Cathode Gage Experiment (CCGE), Charged Particle Experiment (CPE), Laser Ranging Retro-Reflector (LRRR), and the Lunar Portable Magnetometer (LPM). In fine condition. Due to the cancelation of the last three Apollo missions, only some components of the ALSEP 4 ever made it to the moon—the SIDE, CCGE, and LRRR were deployed on Apollo 15, and the ASE and LPM were used only on Apollo 16.
