The version for the TRS-80 Model I had special handling to make it possible to use lowercase letters, even though the hardware itself did not support mixed-case type.

Scripsit dominated its market because, at first, no other TRS-80 word processor was available through the ubiquitous Radio Shack retail stores, with alternatives only being known and made available to the public in the TRS-80 computer press, such as 80 Micro magazine.

Word processors typically require the use of special function keys to access editing commands as opposed to text entry.

[4] Some additional features such as boilerplating and integration with Profile, Tandy's database program for all of their TRS-80 platforms, are available for the disk versions.

The Model 4 version, for example, would inject random text throughout the document if the user held the control key ('@') down for more than a few seconds.

One handy and somewhat innovative feature for the time was the ability to add custom control characters in the printer setup.

This allowed the user to take advantage of new features in a printer that were not intrinsically supported by Scripsit, such as different fonts or colours, or printing extended ASCII characters to produce simple lines and boxes.

This was possible as printer manuals of the day included a full list of supported control character sequences for such functionality.

Isaac Asimov used Scripsit running on a TRS-80 Model II Computer for over nine years, and wrote over 11 million words with the program.

[9] British thriller author James Follett also used Scripsit, running on a TRS-80 Model I, to write The Tiptoe Boys, which was filmed as Who Dares Wins.
