Oberon, the jewel by Niklaus Wirth and Jürg Gutknecht: Operating System, Compiler and Computer.
Oberon Pi is a port of Peter de Wachter’s Project Oberon emulator to the Raspberry Pi OS by Richard Gleaves.
Richard Gleaves is a former UCSD Pascal Project member, and author of the 1984 Springer book “Modula-2 for Pascal Programmers”.
The software changes were mostly limited to the UI, with the goal of flattening out the learning curve for new users of the Oberon system, not only read about in a few places online, but also experienced firsthand after bringing the system up.
Richard also added Andreas Pirklbauer’s changes to the Oberon compiler, to fully implement CASE statements and fix a few compiler bugs.
The main feature in Oberon Pi is its documentation, which includes new user guides Richard wrote for the Oberon operating system and draw application, along with a complete set of Wirth’s original PDF documents on the Oberon language, now made more usable with the addition of TOCs to the PDFs.
