== General Announcements ==
Due to unforeseen circumstances, NDWiki went offline sometime in 2015 (April?). Efforts were made by parties involved to get it back online again, but failed. A year later (April 2016), discussions on how to remedy the situation was started. As I had available time, I offered to set up a server to run to wiki on, and manage it. I only have a "normal" broadband connection at home, which means a dynamic IP address. This is not ideal for running a server, so I asked my local [[Wikipedia:makerspace|makerspace]], [http://bitraf.no/ Bitraf], if I could host the server there - they were willing and agreed. All this took a while, but in the middle of May 2016 I set up the server, installed the necessary software, restored the backup and started fixing stuff that didn't work (some templates, images not showing). Most of the problems were due to my lack of experience with configuring Mediawiki and the software it needs. Anyway, on May 24th, 2016  NDWiki was ready for use again. Enjoy!  [[User:Tingo|Torfinn]] ([[User talk:Tingo|talk]]) 13:45, 29 May 2016 (UTC)
* Upgraded the Wiki to MediaWiki 1.15.1. Please report any problem! /[[User:Mike|Mike]] 12:19, 9 September 2009 (UTC)  
* The new {{tl|Webref}} template should make it easier to make similar referenses and external PDF links got the mini PDF icon ([[Image:File acrobat.gif]]). Also the '''Book sources''' page is updated (try ISBN 82-00-22506-2 to have a look). /[[User:Mike|Mike]] 18:18, 15 August 2009 (UTC)


==License==
== 600 articles! ==
ND Wiki uses the GFDL version 1.2. Wouldn't it be better to upgrade to 1.3 and then to CC-BY-SA, to be compatible to Wikipedia? --[[User:LA2|LA2]] 06:55, 16 October 2009 (UTC)
:Yes! Is it possible to do that in one step? --[[User:Mike|Mike]] 07:44, 16 October 2009 (UTC)


::There are two ways: (1) If you can convince every contributor to relicense their contributions, you can change to any license at any time. I guess this is possible on ndwiki, considering how few contributors you have. How many contributors do you have? If most agree, can you afford to drop the contributions by the rest? (2) The other way is to follow the transition rules in GFDL 1.2 and 1.3, but this requires that you respect some deadline, which might already be too late. --[[User:LA2|LA2]] 08:47, 16 October 2009 (UTC)
This wiki now has 600 articles (or pages if you like)! [[User:Tingo|Torfinn]] ([[User talk:Tingo|talk]]) 19:52, 23 August 2017 (UTC)


:::The deadline for option (2) was in August 1, 2009. NDWiki have the same reason to change as Wikipedia. See [http://lwn.net/Articles/305892/ GFDL 1.3: Wikipedia's exit permit]. Now we need all the major contributors agreement to "upgrade" the license. /[[User:Mike|Mike]] 10:27, 16 October 2009 (UTC)
== MON 15 ==
I just joined NDWiki and would like to contribute. I have not found any doc on MON 15 which is used by NPL, MAC and QED.
Years back I tried to find out what this monitor call wa doing. In my emulator I have this notes:
Old undocumented monitor call, used by NPL/MAC/QED in connection with old open file
  These programs invoke this monitor call using instruction code 161015 octal
  X points to data area to set up
  T is a pointer and is used as a parameter to set up the data structure
  D indicates the buffer length in bytes
Establish data structure to be used by MON 20
Then used by MON 42 to open file (old open)


::::How to do this in practice? We all add a statement (e.g. "everything I write may be licensed through CC-BY-SA") on our User pages? -- [[User:TArntsen|TArntsen]] 10:42, 16 October 2009 (UTC)

:Ref. the undocumented MON 15. I was trying to figure out the moncall myself some years ago. The last information I found was from (from my notes) 'the TSS manual', which must have been {{ND-doc|60.039.01}}
:So it looks like it was a moncall in NORD-TSS (TimeSharing System) and may have been backwards supported in SINTRAN due to those old tools. If it is the same call. I suspect it is, although I'm not sure if the full functionality of the old one is there - if it only needs to work with NPL/MAC/QED then maybe it doesn't. See below for what I basically copied from the TSS manual. Thanks for bringing it up, it reminds me that we need to work on the documentation for monitor calls.

SETUP - Generate a string descriptor
  X = address of string descriptor (5 word object)
  T = location of string
  AD = maximum size of string in bytes
  Descriptor:
    4 character pointers:
      beginning pointer
      end pointer
      reader pointer
      writer pointer
    A string is the characters between the reader and writer pointers.
    reader <= writer and both pointers must be within beg/end
SETUP seems to take T and A and write a descriptor to (X), with reader=writer=beg


:::::If you need my agreement for changing the license of my contributions you have it now. Mike may change the license of my contributions to NDWiki to any license he think is appropriate.<br>So, that would take care of the legality and I can get back to doing real work.

Does anyone have a :BPUN file of the instruction test program?
I would like to have it to test my emulator. The idea is to replace the IOX instructions for terminal input/output with MON 1 and MON 2.
I have tried to find a floppy image with the instruction test program (and use ndfs) to extract it, but without success so far.
:Try this one: https://www.dropbox.com/s/6x2vw7cquaa3b7o/10523D01-XX-01D.image.gz It includes INSTRUCTION-B:BPUN. But note that this test program needs a nearly fully functioning emulation of 16 interrupt levels, ION/IOF instructions, etc. [[User:TArntsen|TArntsen]] ([[User talk:TArntsen|talk]]) 10:04, 19 May 2019 (UTC)
:: As said above, to test with that program, you have to emulate on cpu level, with interrupts, iox calls, cpu runlevels etc. Tingo has put nd100em on github I saw, so you can download that and try with. Btw, am back coding again on that and hopefully will have it booting from a virtual tapereader soonish. Skipping floppy for now until I have running real hw to compare with. [[User:Roger|Roger]] ([[User talk:Roger|talk]]) 10:37, 20 May 2019 (UTC)
:::I got my emulator booting from a (virtual) tapereader recently, however that's not much different from loading a BPUN - but if you're having issues just ask. Of course the tricky part is booting something that needs the full monthy of interrupts, rings, privileged instructions etc.. my emulator is still mostly good for just user level. As for test programs - have you figured out how the instruction-c is to be used? The :TEST and :NEXT file formats? [[User:TArntsen|TArntsen]] ([[User talk:TArntsen|talk]]) 10:50, 20 May 2019 (UTC)
:::: Exactly, it should be very similar to just loading a BPUN, but it will allow that BPUN to pull in more stuff later if it wants if its register compatible. Anyway, the testdisk I use have all test programs as BPUNs, so I can use them by just loading them instead. If you have the TEST and NEXT file endings it's newer. I haven't tried those yet. [[User:Roger|Roger]] ([[User talk:Roger|talk]]) 15:19, 20 May 2019 (UTC)
:::::My emulator is now running the TPE-MONITOR program (with two patches). TPE-MONITOR can load :TEST programs, but most of them requires I/O-handling, paging etc. I have patched the INSTRUCTION-C03:TEST program and can now run all tests without getting the "NOT EXECUTABLE UNDER SINTRAN" message. All tests of non-priveleged instructions like BIT, SHIFT, BYTE etc. work fine. I did, however, need to implement interrupt level changing since the test program runs on levels 1 to 9. The MOVEW instruction works as well with some "tricks" in the emulation code. This test seems to be using the paging system, which my emulator can not handle. Running the tests I found an error in the BCD instructions, an error in floating (the two last bits in the mantissa) and a fault in SUB (carry). Currently I believe there is an error in the stack instructions which I will look further into. It was worth the effort to do this work, but I think there are still errors in the emulation, the test program did not look very extensive....

== PASCAL compiler ==
I am trying to make PASCAL running in my emulator and have extracted
files from ND-10076J.image.gz using ndfs.
The :BRF files seems to corrupted, NRL and BRF-EDITOR reports illegal
BRF control bytes in all of them. BRF-EDITOR lists a number of entries
but some of them looks a little bit strange to me.
The problem may be caused by an error in my emulator, a bad floppy image, an error  in reading the floppy or an error in ndfs.
I have retrieved a number of different files from other images using ndfs. Most of them are OK, but I have problems with some of them.
My first guess is that the problems relate to bad floppy images or the reading of the floppies.
Does anybody have a possibility to e.g. check the PASCAL files, e.g. running BRF-EDITOR - LIST-ENTRIES in an emulator or even on a ND-xxx computer?
[[User:CVS|CVS]] ([[User talk:CVS|talk]]) 11:50, 25 february 2021 (UTC).
:The [[ND-10076J]] image appears to be corrupted, possibly due to being a copy made by an early version of FluxEngine, or other reasons. One definite clue is that the file PASCAL-ERR-J:SYMB, which is a text file, definitely is corrupted. The same file (same size) is also in [[ND-10187J]], where it looks fine. And yes my Linux command line tool which I wrote to examine .brf files also doesn't like the content. [[User:TArntsen|TArntsen]] ([[User talk:TArntsen|talk]]) 11:17, 25 February 2021 (UTC)

:Thank you! I have another question: How can I extract files from the images I find at www.datormuseum.se They seem to be in a format not usable by ndfs.

::I'm terrible when it comes to layout-organization of heterogenous information, I always get stuck! But maybe we could start with a separate sitemap, as you suggest, and add whatever we think of (to start with), and link to it from the front page (which would then just get one more link). The sitemap would need something that would make it easy to go directly to info about some category. Let's think about what we have.. documentation (which is currently the only one easy to find), ND-100 instruction set (pretty well hidden now, although 'random page' will get you there quickly), ND-100 hardware, ND-500(0) hardware, a little bit about Sintran, that piece about floppy formats, then file formats, ND history, compilers/assemblers (it's actually a bit difficult to figure out what we have right now.. I always have to hunt around). I would also like to have a section about Sintran commands (that is, all of them, like for the instructions), monitor calls, ND-500(0) instructions (unless we'll get overwhelmed).

During August this year (2022) the software on the NDwiki server got upgraded. Both the operating system (FreeBSD) and Mediawiki was quite out of date.

NDwiki have https now

During August this year (2022) the software on the NDwiki server got upgraded. Both the operating system (FreeBSD) and Mediawiki was quite out of date. A wish for https was made, so I installed Let's Encrypt certificates and configured apache and Mediawiki to use them. Torfinn (talk) 09:43, 22 October 2022 (UTC)
