A command is defined by any procedure which is exported and has an empty argument list. Commands are activated by a middle-mouse click on a text fragment of the form Module.Command (optionally followed by parameters, which are terminated by ~). Text appearing almost anywhere on a screen can be edited and used as command input. It combines the point and click convenience of a graphical user interface (GUI) with the linguistic strength of a command-line interface (CLI) and is closely tied to the naming conventions of the Oberon language. Oberon has a text user interface (TUI), which is very different from a terminal user interface.

It was presented at the symposium organized for his 80th birthday at ETH Zurich. It details implementing the Oberon System using a reduced instruction set computer (RISC) CPU of his own design realized on a Xilinx field-programmable gate array (FPGA) board. In late 2013, a few months before his 80th birthday, Wirth published a second edition of Project Oberon. Wirth and Gutknecht (although being active computer science professors) refer to themselves as 'part-time programmers' in the book Project Oberon. It was later extended and ported to other hardware by a team at ETH Zurich and there was recognition in popular magazines. The user Interface and programmers reference is found in Martin Reiser's book 'The Oberon System'. The basic system was designed and implemented by Niklaus Wirth and JГјrg Gutknecht and its design and implementation is fully documented in their book 'Project Oberon'.

It was written almost entirely (and since the 2013 version, is described entirely) in the Oberon programming language. The Oberon operating system was originally developed as part of the NS32032-based Ceres workstation project.

The system also evolved into the multi-process, symmetric multiprocessing (SMP) capable A2 (formerly Active Object System (AOS), then Bluebottle), with a zooming user interface (ZUI). The latest version of the Oberon System, Project Oberon 2013, is still maintained by Niklaus Wirth and several collaborators, but older ETH versions of the system have been orphaned. This TUI was very innovative in its time and influenced the design of the Acme text editor for the Plan 9 from Bell Labs operating system. The Oberon System has an unconventional visual text user interface (TUI) instead of a conventional command-line interface (CLI) or graphical user interface (GUI). It was originally developed in the late 1980s at ETH Zurich. The Oberon System is a modular, single-user, single-process, multitasking operating system written in the programming language Oberon.
