BootManager.

Hi, To my understanding, Andre Fischer wrote the original BootManager; the executable for which is now in the ETHZ SVN archive. https://svn-dept.inf.ethz.ch/svn/lecturers/a2/trunk/source/ Documentation formerly on the OCP server is now available from WayBack. https://web.archive.org/web/20151127045022/http://www.ocp.inf.ethz.ch/wiki/… Most likely it was written by Andre. Hopefully someone can confirm or correct that statement. The executable should work on any PC where A2 works. It worked for S3 and should work as well for V4. For a Unix-like system, chain loading can be applied. I appreciate that WayBack prevents loss of the document but don't consider it a good permanent home. I'm tempted to add it to the wikibook, with appropriate acknowledgement of course. Any comments about that? Can anyone confirm the author? Thanks! ...

An Oberon-07 compiler for the ESP32
by Guy T. 23 Mar '20

23 Mar '20

Hello all, Just to let you know that I'm in the process of building an Oberon-07 compiler for the ESP32 chip, based on the Project Oberon compiler. Still a work in progress but a good part of the compiler is working well. It took me around 4 weeks (full time effort) to develop and I'm in the debugging phase since 3 weeks (part time). You can find it here: https://github.com/turgu1/esp32-oberon-compiler <https://github.com/turgu1/esp32-oberon-compiler> Cheers! Guy

P.s. A user can be interested to use BootManager without obtaining a working copy of the SVN repository and without using A2. A machine can have two versions of S3 and no other system for example. Therefore BootManager available independent of A2 seems rational. The document if not the executable also. Regards, ...

EOS new features
by Andreas Pirklbauer 22 Mar '20

22 Mar '20

I have been asked this several times: Since EOS now has finally diverged and uses a different memory layout, the building tools are now also different than the ones for Original Oberon 2013 (=FPGA Oberon). To continue to use the building tools for the original system: http://github.com/andreaspirklbauer/Oberon-building-tools/tree/master/Sourc…

EOS new features
by Andreas Pirklbauer 17 Mar '20

17 Mar '20

Just a quick mini-release note on the latest version of EOS, which has the following characteristics: - elimination of the concept of static base altogether, the MT register, and also the module table MTOrg - the module space now starts at absolute address 20H (instead of 100H), the trap vector is at 04H - no more 64KB limitations from the mod.data, neither for global nor for imported global module data - module loader fixes up all accesses to global and imported global data to a fixed 2-instruction sequence - modules and pre-linked binaries are freely relocatable to any memory address using ORL.Relocate(Bin) - one can construct pre-linked boot-loaders BootLoad.bin consisting of multiple modules using ORL.Link - one can execute pre-linked binaries M.bin at any memory location using ORL.Execute http://github.com/andreaspirklbauer/Oberon-extended Any input is welcome! Thanks for the various suggestions of the past via email. Much appreciated.

Glitch in output of Mail.Wrap.
by peter＠easthope.ca 12 Mar '20

12 Mar '20

Texts.Replace invokes a broadcast message. As I see, every plain old Text viewer does a correct update. The hidden-empty-line glitch occurs only in a Document Viewer. Therefore I must consider the possibility of a bug in a Gadgets module rather than in pre-Gadgets Oberon. I'd rather find a bug in my Wrap source than in a Gadgets module; but until the bug is found and understood I won't be sure where it is. Regards, ...

Re (2): Display.Broadcast() and update of display.
by peter＠easthope.ca 10 Mar '20

> You only can speed up, if you reduce the nbr of Screen updates. Not > an easy task. Wrap assembles the reformatted Text by copying little buffers one after another. After a whole new buffer is built, Replace is invoked. So only one Replace; hence one update. Wrap is fast. Rarely more than a few ms. CutLines is noticeably slow. When it hits a word longer than the target width you watch the empty lines being inserted: clunk, clunk, clunk ... I admit a subtle glitch probably remains but Wrap is useable. If fact Oberon Mail is useable now that the worst bugs are fixed. Regards, ...
