Apollo Block II Entry Monitoring System Assembly. Unit weighs 21.75 pounds, measures 9 x 8 x 10, and has its original Autonetics manufacturer’s label affixed to one side, which reads: “Entry Monitor Control Assy…Ser. No. 06359-0188-0005; Mfg. Date: May 7 69.” Side also bears stamped “Accepting Terminal Testing Time,” and “Acceptance Vibration Time” labels, with a “Class III Not For Flight” label affixed to the bottom panel, which indicates it was likely a training unit, but does not preclude possible flight history prior to its downgrade. Assembly also retains its original umbilical and plug. Front of the assembly is highlighted by the ?V instructions printed on the EMS scroll. This scroll would provide a visual aid by which the astronauts could monitor an automatic reentry and fly a manual reentry if needed. Other features include a range-to-go digital display under the scroll, the 0.05 velocity indicator, and the roll/attitude indicator needle in the lower left. Also present is the VHF mode selector switch, the ?V setting switch, and the function dial with 11 different settings, three of which are self-test provisions. Four small squares of Velcro are affixed to the frame of scroll. In overall fine condition. This is the first such unit we have ever seen available for public auction. RR Auction COA.
