The TRS-80 Model 100 is a notebook-sized portable computer introduced in April 1983.
It was the first commercially successful notebook computer, known as laptops today, as well as one of the first notebook computers ever released.[1]
It featured a keyboard and liquid-crystal display, in a battery-powered package roughly the size and shape of a 1" 3 ring binder.
The 224-page, spiral-bound User Manual is nearly the same size as the computer itself and adds to the value of the Model 100, particularly if it still has the pouch in good condition that was included to help protect the manual from damage during the owner's travels.
The Model 100 was made by Kyocera, and originally sold in Japan as the Kyotronic 85.
Although a slow seller for Kyocera in Japan, the rights to the machine were purchased by Tandy Corporation and was wildly popular.
This popularity was further boosted by there even being a monthly Model 100 magazine that shared stories of people that owned them, including astronauts aboard the NASA Space Shuttles, and always included program code listed that was submitted by subscribers to the magazine.
The Model 100 was sold through Radio Shack stores in the United States and Canada and affiliated dealers in other countries around the world.
It became one of the company's most popular models of all time, selling 6,000 units in the first month, with over 100,000 units eventually being sold globally before being discontinued in 1991.
The Olivetti M-10 and the NEC PC-8201 and PC-8300 were also built on the same Kyocera platform, with some design and hardware differences, which limited their compatibility with the Model 100.
The Model 100 was originally marketed as a Micro Executive Work Station (MEWS),[2] although the term did not catch on and was eventually dropped.
