The 1980s gave us some of the most iconic computing interfaces ever designed. From the Borland Turbo Pascal IDE to Norton Commander, these text-mode interfaces proved that you don’t need a GUI to be productive.

The Machines

The IBM PC 5150 launched in 1981 and changed everything. Here’s what it looked like:

The original IBM PC came with just 16KB of RAM and a cassette port. No hard drive. The operating system fit on a single floppy disk.

The Software

DOS applications had a distinctive look - text-mode interfaces with box-drawing characters, function key bars at the bottom, and pull-down menus.

Some legendary DOS software:

The Sound

The PC speaker was all we had. No Sound Blaster yet. Just a single square wave channel. But composers made magic with it.

The limitation of a single voice forced programmers to be creative. Some of the most memorable game music was composed for the PC speaker.
