Recovering a 1965 IBM Executary tape for Jennifer (Patreon)

Viewer Jennifer had an unusual, very wide band tape media. She thought it was recorded in 1965 when she was 4 years old, and may contain her voice. It said IBM on the side of the tape. She wondered if I knew what it was. I did! It's for an IBM 214 Executary dictaphone. She send the magnetic band to me, I finally finished restoring my 1965 Executary, and... Well, see this uncut raw footage.
