Space probes, smart phones, dumb phones, calculators,...

Space probes, smart phones, dumb phones, calculators, and even some Intel motherboard chips are running TRON systems or their derivatives.

This system is THAT big. Perhaps, today there are more choices among embedded operating systems, and more devices are simply running Linux, but I think the claim that in 2003 TRON used to be the most popular operating system is somewhat substantiated.

Now, tell me, HOW COME no one in the West have heard about desktop version of TRON that could run on i286/386, and, from what I can tell, Sun workstations?

Edu-rant is over, time to show you the system :D Follow me!

These days, finding the installation media for the B-right/V OS itself can be hard. But the operating system is still sold on Amazon as "Chokanji V, TRON runs on Windows" input system. 超漢字V means "Super Kanji 5", by the way. There is MacOS X version, too.

Either version is just installing BTRON in VMWare, and runs the input method somewhat seamlessly.

Archive.org has installation media for B-right/V 4.5 from 2006, but it will not run in Qemu properly. https://archive.org/details/chokanji

The iso contains a file called bright00 which is a boot floppy for B-right/V installer. It should work on most i386-based computers, but it requires supported CD, IDE and mouse. After a bit of tinkering with PCem, I managed to make it work.

The installer shows not one but two splash screens: B-right/V TRON OS first, and Chokanji V second. Then it starts a very simply-looking disk partitioning and OS installing tool. Make no mistake, at this point TRON OS is already running. The mouse cursor is a bit funny/unusual, showing cup of green tea whenever there's a delay ("hourglass").

While it loads, you might contemplate: why did they bother to make a whole OS? Well, my dear friends, they needed a system that could support kanji, RTL and vertical input before Unicode was invented.

The installer partitions and formats the disk, asks whether you want full setup (all fonts) or minimal setup (less fonts), copies the files, and invites you to remove the floppy from the drive 0 and reboot.

First launch.

The system is booting, and it is quite fast. Before we can begin, we should answer a few simple questions.

Do we want BTRON style settings or Windows style settings?
Which key you want as KANA key?
Romaji input - BTRON style or Windows style?
Ctrl+ZXCV behaviour - BTRON or Windows?

I am curious how things are in BTRON, but not enough to set it to non-Windows and get lost/confused.

Welcome to Chokanji! Do you want BTRON-like settings or Windows-like settings?

Which key you want as KANA key?
Romaji input - BTRON style or Windows style?
Ctrl+ZXCV behaviour - BTRON or Windows?

All done. If something is wrong, check the settings, or consult with the manual

The desktop after the launch has two important windows. The smaller one shows your running applications - inbox, applets tool, "Notice from Personal Media Inc" and "Choukanji V tutorial". The bigger window has buttons to create new documents of all the registered types (text, drawing, cabinet, email, browser and many more).

Windows don't have any controls or menus. If you want to interface with a window, you just right-click it to call a pop-up menu. It has application options like "save" and "exit", as well as OS-wide options (start an applet, rearrange windows). The pop-up shows a long list of applets, let's check them out!

The most important applet of them all is System Settings. You can change things from wallpapers to PCMCIA IRQs here.

Then there is glossary/help system. You search for a topic, and then you can read a document about it. Note that the help document here has hyperlinks. In fact, "Choukanji V Tutorial" launched on the start is also just a BTRON document. TRON specifies a standard data bus for data exchange between the apps, so it only makes sense they'd do that.

Then there's kanji search, which is super important for anyone who works with kanji. Like, seriously.

And then there's a post-code look up applet. It can find a Japanese post code by address, and address by post code. I have no idea why include this into your core OS, but perhaps it's an important tool for businesses.

I wanted to tell you more about other applets, like on-screen keyboard, calculator, backup, clock and file manager, but I found a KITTEN.

This app serves the same purpose as the "mouse pointer trail" in Windows, but instead of the trail, your computer mouse is chased by computer kittens. You can have up to 8 of them on your desktop, and not all of them will be following the cursor - some will get tired and will fall asleep on the spot.

You can give belly rubs to all your computer kittens. Hey @netkitty can I give you a belly rub too?

Time to explore the business applications. To start a business application, you either open an existing document, or choose the document type from the "box of templates". Whenever you click a link in the "box of templates", the OS will ask you to give a name to your new file, and will add it to the main "Chokanji" window. Internet browsing session is also a document.

If you open lots of documents, it creates a lot of clutter in your main window, which is incidentally a task switcher. Not very convenient.

Among document templates, there is "Applet window" template, that allows to run some of the applets not listed in the right-click menu. Disk utility (the one used by installer) and shell are among those. There's a curious file called "unixemu", but trying to execute it causes a segfault, which creates a window with lots of unnecessary for a regular user information.

A few more boring applets that I didn't include in the list were serial terminal and dialer.

Text processor looks simple - just a window for text input, but it is actually a proper word processor, with formatting and such hidden behind the right mouse button click.

Drawing application has an external movable window with a tool palette. It seems to be vector editor, but the OS supports common image formats (GIF, JPEG and probably more).

There's some sort of email client, but email session is a "document". There's a web browser (I'll show it to you soon), and a spreadsheet tool with yet another multi-window interface. Note how trying to copy something from a spreadsheet asks for the clipboard format - plain text, CSV, image or "precise".

There is also some sort of cardfile application, and there seems to be an ability to create SCRIPTs, but it will be impossible to figure out without reading the documentation, so maybe some other time.

Setting up the Internet requires two things. First, invoking "System settings" applet and adding your network card there. There is a wide list of supported cards, from ISA and PCI to PCMCIA. Then, there is a separate applet called "Network settings" that is used just for IPv4 settings - set up your IP and DNS there. It doesn't seem to support DHCP.

After that, you need to create a "Browser document" that will allow you to access some of the web over HTTP. The default site is chokanji's home page.

The browser is quite basic, with GIF/JPEG and some table support, but generally it feels close to Links than to even Internet Explorer. Google works, but HTTPS sites won't. It IS pretty cute.

And that's basically it. This is all B-right/V Business TRON OS implementation has to offer. To shutdown your computer, RMB click main "Chokanji" window and choose "Close". It will create a pop-up "Do you want to finish?", and after that the only things left will be KITTENS and a dialogue window "Chokanji has been shut down. Reboot. Finish". Kittens will follow your mouse, but they always stop at pop-up window boundaries, it seem. That leaves them helpless against surprise belly rubs, highly recommend.

After you press "Finish", the screen will show white text on the black screen: "Please turn off the power switch".

It's time to make some green tea and reflect on all the incredible software that we use daily and don't notice. Don't get me wrong, there is massive difference between desktop B-TRON, embedded I-TRON, and Nucleus on phones and cameras... But it is more ubiquitous than JAVA, and yet almost no one knows about it.

@nina_kali_nina @fkinoshita It's kind of similar, but unlike OLE, every file is also a directory and actually contains all the documents linked into it more or less. It's similar to how hard links work on Unix, although the name is associated with the inode equivalent (the real object), not the directory entry equivalent (virtual object a.k.a. link record)

@nina_kali_nina unixemu is a system program (basically a kernel module), not a user program. It only implements Unix API compatibility, and not a shell environment. A Unix shell environment with development tools can be found at http://www.chokanji.com/developer/download.html (specifically selfenv.bin). Once you've installed it, you can run /SYS/ucli from the console to get a Unix shell, although it's a bit limited

@nina_kali_nina B-right/V's appearance barely changed across versions, with probably the biggest change being the wallpaper. Even the last version of its 16-bit predecessor, 1B/V3, looks pretty similar (although 1B/V1 and 1B/V2 were much flatter). AFAIK there were some major changes between B-right/V versions that weren't immediately obvious (for instance, B-right/V R2 a.k.a. Chokanji 1 added support for all codepoints of the TRON character set and Chokanji 4 added shared libraries)

@nina_kali_nina Here's Chokanji 4, which is very similar to Chokanji V (AFAIK the biggest changes in V are the VMware guest enhancements and a different beginner's guide)

Andrew Warkentin replied to Andrew

@nina_kali_nina And here's 1B/V3. Despite looking similar, 1B and B-right/V are actually distinct OSes, although AFAIK at least some code was carried over from 1B to B-right (mostly in the GUI and applications). Despite being released in 1996, 1B/V3 is still a 16-bit 286 protected mode OS (the first versions came out in the late 80s). The demo version fits on 2 floppies but still has quite a bit of functionality

@nina_kali_nina I have both Chokanji 4 and V running in QEMU 5.2.0. 4 installs fine without any special considerations. The issue with V is that Chokanji's VMware driver doesn't get along with QEMU's limited and somewhat broken implementation of the VMport. Disabling the VMport by using the -M pc,vmport=off option to QEMU fixes the VMport incompatibility (4 lacks the VMware driver). The only other QEMU-related issue I've found is the floppy doesn't work so you have to boot from CD

@nina_kali_nina Since TRON is more of an architectural specification than a concrete OS implementation, I’m guessing these have way more differences than similarities.
