Reel-to-Reel Wire Recorder

Description (Brief)
In 1945 William Lear purchased a license from the Armour Research Foundation and made wire recorders like this “Dynaport” unit. The Dynaport combined a wire recorder with a disk record player. The user could play records and make a wire recording of the contents. Users could also connect the Dynaport with a radio and record programs off the air.
The Dynaport did not sell well and Lear turned his attention to other products like small business jets. Years later he redesigned a tape cartridge system and became a driving force in the introduction of 8-track tape players for automobiles.
