. This version added incremental new features to the word processor, such as additional printer commands, full cursor-control (to take advantage of the PC's Home, End, PgUp, and PgDn keys), and a native 80-column mode.

80-Column Updates

The original versions of SpeedScript were designed for the 40-column Commodore 64 and the 22-column VIC-20. When the Commodore 128

 was released, featuring an 80-column display, many users requested an updated version of SpeedScript to take advantage of this new capability. In June 1986, COMPUTE!'s Gazette published SpeedScript-80, a short patch

 for SpeedScript 3.0 or higher, which enabled the use of the VDC's new 80-column capabilities on a Commodore 128 running in 64 mode. However, this did not take advantage of the C128's expanded memory, and a few minor commands were eliminated due to the alterations to the existing code. SpeedScript-80 was enhanced soon after with SpeedScript-80- Revisited, by Bob Kodadek.

A native version for the C128 called SpeedScript 128, also written by Kodadek, was finally released in October 1987. This version eliminated the problems of the patch and took full advantage of the C128's 80-column screen, its expanded memory and the enhanced keyboard.

In December 1987, COMPUTE!'s Gazette published Instant 80, a utility for the C64 version of SpeedScript that allowed 80-column document previewing (though not editing) on a standard C64. This was done by using half-width characters on a high-resolution graphics screen.

Spelling checkers

Although SpeedScript did not include a built-in spell checker

, additional utilities were soon published to fill this hole. In December 1985, SpeedCheck was published in COMPUTE!'s Gazette. This external utility accepted SpeedScript files (as well as those from compatible word processors, such as PaperClip
