Also in April 1983, Radio Shack released the TRS-80 Model 100, one of the first laptop-portable computers.

Manufactured by [[Kyocera]], the Model 100 features an [[LCD]] with 8 lines of 40 characters each, 8 kilobytes of RAM (expandable to 32KB), and is powered by AA cell batteries (or a plug-in adapter).  A built-in [[modem]] and 25-pin RS-232 serial port provided connectivity.

With the rudementary operating system held in [[ROM]], the Model 100 (and the improved model, named the [[Tandy 102]]) was ready to use immediately after sliding the power switch on, and work would be held ready when switched off, making it convenient to use for a few moments at a time.  This speed made the Model 100/102 useful well after powerful—and slower-booting—laptop computers became common.

The Model 100-series computers also found popularity as a field-portable communications terminal due to its light weight and simplicity.
