Hi Most probably both of the following doctoral theses build the groundwork of the book: Markus' doctoral thesis (1997) is here: https://www.research-collection.ethz.ch/handle/20.500.11850/143299 Xiaobing's doctoral thesis (1998) is here: https://www.research-collection.ethz.ch/handle/20.500.11850/143646 br Jörg Am 03.01.22, 16:19 schrieb "Oberon im Auftrag von Skulski, Wojciech" <oberon-bounces(a)lists.inf.ethz.ch im Auftrag von skulski(a)pas.rochester.edu>: Peter wrote: >From work on Andre's tutorial pages, I'm learning >about Gadgets in ETH Oberon.

Peter: are you aware of the book by M.Kottman, X.Qiu, and W.Schaufelberger titled "Simulation and Computer Aided Contrpl Systems Design using Object-Orientation", ISBN 3 7281 2748 5 ? The authors worked at ETHZ Institut fuer Automatic. Dated 2000, printed by VDF, which is the ETHZ printing office. I am afraid it is out of print. I have a copy. I asked them about PDF, and they said they did not have it. But perhaps they did not try hard enough to find it. This book uses ETH System 3 as the programming environment for simulation and control systems. It is very comprehensive and full of good examples. I do appreciate this material, though it is not my field of study. It would be fantastic and very useful if this work could be rescued and saved for posterity. Happy New Year!

Wanted: Oberon Syntax in TextMate, Sublime Text or Atom Grammar
by Treutwein Bernhard 01 Jan '22

01 Jan '22

Does somebody have grammars for Oberon / Oberon-2 / Component Pascal / Active Oberon as grammar for TextMate / Sublime Text / Atom Background: Github wrongly classifies Oberon / Oberon-2 / Component Pascal / Active Oberon as Modula-2. I opened quite some tiome ago an issue in the github/linguist project (https://github.com/github/linguist/issues/3888) and they don't accept EBNF grammars. -- Bernhard Treutwein

Clock and calendar in A2.
by peter＠easthope.ca 31 Dec '21

31 Dec '21

Greetings for the New Year, The list is awfully quiet now. Here's a frivolous question. In A2, System > Clock gives a digital clock. Similar for calendar. Should be possible to start the clock with a command in the Autostart section of Configuration.XML but I haven't found the command or source. Ideas? Thanks, ...

Oberon initial ideas by Wirth
by Pablo Cayuela 24 Dec '21

24 Dec '21

Dear fellows, I've recently discovered more material related to Project Oberon, Ceres Computer and even to Lilith Computer and MEDOS on www.bitsavers.org (fascinating site) at Software and Computing Archives. The site was already mentioned many times in the Oberon list related to many articles and documents hosted there. I'm amazed to read some of the first emails by Prof Niklaus Wirth on the starting ideas to design a new operating system while at Xerox sabbatical visit. I hope you enjoy it as well as me. I don't know if it was mentioned before, but in case it is no, here it is: http://www.bitsavers.org/pdf/eth/ceres/OberonBasicIdeasNW.pdf Best regards, Prof Pablo Cayuela Argentina
