Wojtek > How can I proceed, in practical terms, to use your JS emulator for development? Perhaps we should start discussing, WHAT you want to change. At the moment I see three different levels of HW modifications: easy, more difficult, impossible. Basically, see an emulator as virtualization. In virtualization you have a host machine (where the emulator runs on) and a guest machine (this is the FPGA board). I ignore „containers“ at the moment Easy: if you want to extend the RISC-5 instruction set in Verilog (eg add an autoincrement instruction) the modification of the emulator is rather straight forward. I neglect the fact that you have to modify the Oberon-07 compiler to use this new instruction, because this is not important for the emulator. More difficult: if you want to add IO mapped HW (eg Ethernet or Wifi) or memory mapped HW (eg color display) to your FPGA and the host machine has an equivalent of this HW, with a little bit of effort the emulator can be modified to map the IO register commands or new memory layout to the corresponding host HW. Impossible: if you want to add HW to your FPGA and the host machine does not have an equivalent HW (eg a neutrino sensor) then it‘s impossible for the emulator to mimic the new FPGA HW. br Jörg

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

Thanks Hans. My copy of _Programming_In_Oberon_ shows first printing in 1992.

When I initialized the Computers table a few years ago, the headings including "Boot Store", "Memory" and "Persistent Store" seemed reasonable. Now I'm reviewing the table and imagining how it might be improved. Suggestions? Change organization? Add or remove content? Thanks, ...
