Srinivas, > Here is my understanding of NO boot method. Read it when tired. Didn't spot any glaring errors but that isn't a strong claim. From a google of "site:ethoberon.ethz.ch boot" these pages seem most relevant. http://www.ethoberon.ethz.ch/bootman.html http://www.ethoberon.ethz.ch/bootmbr.html http://www.ethoberon.ethz.ch/bootstrap.html Regards, ...

Dear Peter, OLR OPS.Mod not compiling. I am on x86 and Linux. I am using olr160330.tgz + gadgets030105a.tgz. Which olrYYMMDD.tgz is better? I mean, everything compiles. [Not sure why EditTools.StoreAscii doesn't work, even for .Mod files. Till now I was working with Basic system. Now trying to build the whole system with gadgets and check.] With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/

Oberon System V5 - SETUP Key
by thomas.kral＠email.cz 09 Apr '16

09 Apr '16

Hi, Just wish to share my little discovery, on Ceres-2 workstation there is a SETUP key, marking a Viewer with a Star Marker. On FPGA Oberon System, with PC Keyboard attached there is no such key, but Ctrl + Z combination, places the Star Marker. Any command accepting thus selected viewer can be used with * parameter, according to The Oberon System book by Martin Reiser. I found that e.g. when having more Edit Viewers opened, that Edit.Search will start searching in the viewer that is marked. Tomas

Dear Guenter, I have now completed my first task of porting Ceres-2 Splines.Mod to FPGA Oberon System V5. As it is part of Draw package. I now wish to focus on Paint.Mod, the Modules needed below, Bitmaps -> PictureFrames -> Pictures -> Paint I have Bitmaps from OLR and the rest kindly provided by yourself. I would like to start with Bitmaps, as it is not portable code, I wish to know some background, in case it is documented somewhere. Could you please advise? Many thanks Tomas

Bounce rate at eth oberon mailing list is 40%!

Dear All, Further to Chris's missing mail information, I wanted to just re-check similar experience from my end too. In my mailing list subscription page I noticed that, my mail bounce rate is 2.0 out of 5.0! Also sometimes I see, your replies to me come very late. I mean, your replies of evening to my message comes earlier than your replies of morning, in a day. With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/

Trying to understand vertical scrolling
by Srinivas Nayak 09 Apr '16

09 Apr '16

Dear All, When I MR click on scroll bar of System.Text, I see that instead of directly going to the beginning of System.text, it takes several MR clicks to reach line number 1 of System.Text I re-read the book to understand what is happening. I found, in Martin Reiser's book, section 2.4.3, it is written that: Then: - Clicking the right key scrolls to the beginning OF THE TEXT. ... The following interclick events are also defined.: ... - Interclicking the right key while pressing the middle key scrolls to the beginning OF THE DOCUMENT. I rechecked and found that interclick takes me directly to the line number 1 of System.Text. Not the (only) MR click. [In both the statement in the book, "scrolls to the beginning" is in Italics. Only difference is in the phrase "of the text" and "of the document".] Can you kindly help me understand this? With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/

Project Oberon 2013 RISC.img
by thomas.kral＠email.cz 09 Apr '16

09 Apr '16

Hi, I have noticed some changes prof. Wirth made to some modules. History is documented at his website. I have recompiled modules with recent changes, as the time stamp of original RISC.img is March 3rd 2015, and last changes are dated March 7th 2016. Now I wish to make backup my uSD card and produce RISC.img. How can I do it with dd command, as the image size much smaller than 2G uSD capacity? Many thanks Tomas

Re: [Oberon] Which file saves video configuration value in NO
by peter＠easthope.ca 08 Apr '16

> Which file in Oberon saves video configuration detail? This is my understanding. Hopefully my errors are corrected by someone more knowledgeable. Video configuration occurs before a file system is available. The System.Log reports mounting of volumes. This would not be possible without a working display. Note that this arrangement is different from Linux where X is started after the system is operational. The usual means of adjusting the display configuration of an installed system is by config strings and the boot loader has a capability to allow this. A google of "site:ethoberon.ethz.ch video" will give a page with title "Display support". Config strings are near the bottom. When N.O. runs directly on a PC the config strings are found quite easily. When N.O. runs under an emulator they can be a little more difficult to find. With QEMU I had to set the Scroll Lock or press the Shift key at the right point. For vbox you might hunt with google for instructions about interaction during boot loading. A good description of the boot process is pertinent to this topic also. Regards, ...

OLR ARM in Android
by peter＠easthope.ca 08 Apr '16

Native Oberon can run on the bochs app in Android. I guess OLR X86 can work similarly on bochs. Has anyone made OLR ARM work in Android? More efficient than X86 emulation. Thanks, ...
