In 1981, the first Motorola cellular phone, consisting mostly of a big battery, was marketed almost exclusively to police and emergency services. Few other customers could afford it.
The development of technology that could “hand off” a call from one cell tower to the next was a huge achievement at the time. I like the way the museum curators adjusted the appearance of this display, using Lucite and perforated steel to capture that “modern” 1980s look.
I have a DVD of an early Hong Kong gangster movie in which actors talk into Motorola DynaTAC phones. I wish I owned one. Imagine pulling one of these monsters out of your briefcase during a business lunch.
