Also MSX-DOS version 0.26 / 0.12 has been encountered in the wild. Should we consider this an official release with unknown origin? Or is this an 'it has escaped from the lab' version?

Ehmm.... "distributed with Sony BDS-C" ...... it seems strange for a Sony product, maybe a mistake???

Or maybe we can find an explanation here: https://www.msx.org/forum/msx-talk/development/bds-c-for-msx... ??? (adapted from CP/M ..... so the coder has worked with a pre-version and Sony does not have checked that, maybe the coder was a tester for Microsoft....)

The link with BDS-C is unclear. But it can for instance be found on the screenshot of Generation MSX. However, this version pops up in different locations as well. There is an Aackosoft disk with this version, MSX Club Magazine has used it... All of these uses can be accidents of course, and it remains unclear where its origin lies.

Examining all the evidence, I'm convinced that it's legit and it predates version 1.00.

I've found this document: https://simson.net/ref/1994/Microsoft_DOS_History.pdf

Bill Gates himself recognises that Lifeboat (the company who created BDS-C) had a great role with CP/M to put order in the available OS (it was a Tower of Babel before). So it indirectly confirms that this pre-version 0.26 of MSX-DOS is official.

Interesting book. I will definitely read it. Thanks.

I've read the whole thing upon the start of development of MS-DOS 3. That's where things get less interesting from a MSX point of view. MSX-DOS even gets a brief mention on page 23, messing up release dates for the MSX 1 system and MSX-DOS. But who cares. Also, Microsoft and Kay Nishi worked together as early as September 1980! (page 11)

However, I don't see a link to BDS-C and/or MSX-DOS 0.26. Lifeboat only was a software distributor, they didn't create BDS-C, Leor Zolman did.

There is another reference though to MSX-DOS 0.26 and it's outside the MSX world. I have mentioned a testdrive by IS Systems in another thread on this forum. The contents of this document aren't really interesting, but they confirm existence of the version.

Most importantly, they mention using Sony hardware. I suspect that's the common origin of this version. Sony, as a developer of the 3.5 inch floppy system, may have had early access to MSX-DOS. But I cannot prove anything I have just said. It's anyone's guess.

While I'm at it, I have another wild guess. In the list of MSX-DOS 1 clones, three major South American parties emerge. Sharp/Epcom, Microsol, and Telematica/Talent.

I have found a history of Telematica/Talent online, and it describes acquiring a license for MSX system roms at a bargain price. Nowhere other software licenses are mentioned. Could it be they never got the rights to distribute the official MSX-DOS? And neither did Sharp/Epcom nor Microsol? And is this why all three of them developed their own versions?

Again, my guess is as good as yours. I really don't know. Maybe forum users from the region can tell us more. I'm just being curious as why this has happened...

The MSX-View page on the wiki states that "HALNOTE applications are compatible with MSX View."

I tried some .APL executables from HALNOTE on the FS-A1GT MSX-View and they're not recognised as applications. Is there any special procedure to run them?

The first mention about HALNOTE compatibility came from an edit on 18:30, 11 August 2016 by Gdx.

I never use Halnote or MSX-View. I don't have the discs or the cartridge. If I wrote that, it's probably because I saw it somewhere on a Japanese site.

I just did a quick little research. This site says it appears the Halnote apps work but without confirming.

元々はHALNOTEと呼ぶものでありDOS2用に改良されたものでソフトは互換性があり
HALNOTE用のアプリケーションはView環境でも動作するらしい。

Edit: This site says Halnote apps can work on MSX-View:

MSXViewは、HAL研究所が1987年にMSX2向けに開発したGUI「HALNOTE」をMSXturboR向けに転用したものであった(従来のHALNOTE用のアプリケーションもMSXViewでも動作させることができた)。

On this site you can found software for Halnote and MSX-View. Files have the .BOK extension not .APL.

Some software from this free software collection work also on Halnote and MSX-View.

I have created a page for MSX-DOS by Telematica. I first learned about this version when I got a public domain disk from Dutch HCC MSX-gg in the early 90's. I liked the extra's it had over the official MSX-DOS and I used it on my main MSX-DOS disks back in the days.

Only recently I learned about its origins, when I discovered its source code in the MSX-DOS kit. Which is kind of a reward for me, because back then I dreamed about adding even more commands. I remember having printed a complete disassembly of command.com and trying to understand it. That idea never came to live, and now, more then 25 years later I get the original commented source code. B-)

Back on topic, the Wiki page provides a nice overview of the extra internal commands and the options of config.sys. I wonder if any real device driver has ever been made...
