What Did IDEs Look Like 30 Years Ago? Exploring Text‑Mode Development Environments

In the late 1980s and early 1990s, integrated development environments (IDEs) on MS‑DOS were primarily text‑mode applications built on a Text User Interface (TUI). Although they lacked graphical windows, they offered programmers the ability to write, compile and debug code within a single environment.

One early example was the built‑in EDIT.COM editor, a full‑screen TUI editor that featured a menu bar, dialog boxes and a status line. While not optimized for source‑code editing, it demonstrated the level of interactivity achievable on DOS.

A more sophisticated IDE was Borland’s Turbo series, such as Turbo C++. It provided syntax highlighting, an integrated compiler, a debugger, project management tools and a comprehensive reference manual, enabling developers to complete the entire development cycle without Internet access.

Users noted that Borland’s IDE was dazzling but could be hard on the eyes after prolonged use.

On Linux, IDEs were less mature; while editors like Vim and Emacs existed, they did not provide the same integrated experience as DOS‑based Turbo IDEs, leading many programmers of the era to prefer DOS IDEs for development.
