The TRS-80 Model 100
was an early portable computer
introduced in 1983. It was one of the first notebook-style computers, featuring a keyboard and LCD display, battery powered, in a package roughly the size and shape of notepad or large book.
It was made by Kyocera
, and originally sold in Japan
as the Kyotronic 85
. Although a slow seller for Kyocera, the rights to the machine were purchased by Tandy Corporation
, and the computer was sold through Radio Shack
stores in the United States
as well as affiliated dealers in other countries, becoming one of the company's most popular models, with over 6,000,000 units sold worldwide. The Olivetti M-10
and the NEC PC-8201
were also built on the same Kyocera
platform, with some design and hardware differences. It was originally marketed as a Micro Executive Work Station
(MEWS), although the term did not catch on and was eventually dropped.
