Flat-slab smartphones have been in vogue for the better part of a decade, but folding-screen tech may be poised to bring back the classic clamshell. While Motoralo’s streamlined Razr is a touchstone for a whole generation, the older Motorola MicroTAC is arguably the phone that established the trend.

First produced as an analog mobile phone in 1989, the MicroTAC sported a unique folding keypad cover that doubled as a mouthpiece. Eventually, the design would evolve into its reverse for Motorola’s also-iconic StarTAC design, which would put an earpiece on the top and the buttons on the bottom. Cell phones would never be the same again.

Today, most cameras not only focus automatically, but they can even recognize faces or lock onto eyes of their own accord. In the ’80s, it wasn’t quite the same. By the time of the Maxxum’s release, companies like Nikon and Pentax had already released single-lens reflex cameras with autofocus capabilities but with an awkward catch: these implementations required motors in the lenses themselves to make the magic happen.

Minolta’s offering, by contrast, was the first SLR to integrate its autofocus sensors and motors into the camera’s body, allowing for smaller and cheaper lenses, an approach that would ultimately become common. Minolta didn’t have much time to revel in its success. The Maxxum’s autofocus tech was ultimately found to infringe on a patent held by Honeywell, and in 1991, Minolta was ordered to pay a $127 million settlement.
