Scripsit is a word processing application written for the Radio Shack TRS-80 line of computers. Versions were available for most if not all computers sold under the TRS-80 name, including the Color Computer and several pocket computer designs, as well as the Tandy version of the Xenix operating system. Some of these versions were tape-based and have no disk features.
Scripsit was a rudimentary word processor. It has basic text entry and margin controls, as well as word wrap. Many versions tied to specific platforms were available, and each had its own set of features. Most versions supported variable width fonts, specifically for daisy-wheel printers. None had support for graphics other than some character macros depending on the version. The Model I version even had special handling for lowercase characters.
Despite its limitations, it was seen at the time as a killer application for the TRS-80 line of machines, along with other breakthrough applications such as VisiCalc. The software market moved quickly, however, and its popularity soon gave way to WordPerfect running on the IBM PC.
Word processors typically require the use of special function keys to access editing commands as opposed to text entry. This proved to be a challenge on the TRS-80 Model I and Model III computers, as their keyboards had no non-typewriter modifier keys—not even a [Control] key. Instead, Tandy drafted the '@' key to access features such as margin control and load/save.
