Texas Instruments 89 and Titanium

Operating Systems (Motorola 68000)

AAShell

Another boring aping of the Windows appearance (Start menu blah blah)

https://www.ticalc.org/archives/files/fileinfo/156/15664.html

BlitZ K*

Something that’s “designed to look like a file manager”, whatever that means.

https://www.ticalc.org/archives/files/fileinfo/95/9513.html

Brain

Capable of executing and manipulating files.

https://www.ticalc.org/archives/files/fileinfo/135/13500.html

Bureau2000 (new)

While this is claimed to be buggy, it apparently has “Advanced functions”.

https://www.ticalc.org/archives/files/fileinfo/181/18156.html

Compuease Faraday Anywhere

No idea what the functions of this thing are.

https://www.ticalc.org/archives/files/fileinfo/396/39637.html

Console emulation (potential)

Whether these emulators support operating systems for these consoles is unknown; it must be looked into further. Consoles without meaningful OSes are not included.

9801 shortcuts…

https://www.ticalc.org/archives/files/fileinfo/83/8359.html

https://www.ticalc.org/archives/files/fileinfo/137/13788.html (developer)

Einstein 4.0

Reminiscent of Windows, with nice dithering on the folder icons.

https://www.ticalc.org/archives/files/fileinfo/404/40489.html

Emby^2

Some BASIC only Windows clone, which the creator claims was quite challenging.

https://www.ticalc.org/archives/files/fileinfo/277/27744.html

EZOS 2.0

Some BASIC shell with error handling.

https://www.ticalc.org/archives/files/fileinfo/118/11816.html

Fast Shell

It must be fast, and it has some menus.

https://www.ticalc.org/archives/files/fileinfo/127/12752.html

Ginny OS Beta 3

Pleasing looking OS with actual greyscale.

https://www.ticalc.org/archives/files/fileinfo/206/20659.html

GPShell

Has two versions, with the Lite version obviously containing less. Menus , item creation, etc.

https://www.ticalc.org/archives/files/fileinfo/357/35728.html

https://www.ticalc.org/archives/files/fileinfo/396/39630.html (lite)

GroupOS

Categorizes programs by what they do, instead of their file type solely.

https://www.ticalc.org/archives/files/fileinfo/226/22660.html

Hard OS

Has both English and French versions. Seems functional.

https://www.ticalc.org/archives/files/fileinfo/279/27946.html

Icons Program Management System

Has screensavers, backgrounds, and of course, icons.

https://www.ticalc.org/archives/files/fileinfo/65/6524.html

Integrated Desktop

Consice and detailed “icon” desktop interface shell. Lots of languages and applications.

https://www.ticalc.org/archives/files/fileinfo/284/28443.html

Lin4Ti

Simple and silly clone of a Linux shell.

https://www.ticalc.org/archives/files/fileinfo/310/31047.html

Linux 900

No features described, but it apparently has a graphical interface.

https://www.ticalc.org/archives/files/fileinfo/260/26005.html

NightHawk Mobile 4.7

Interface reminds me of some sort of PDA or phone. Seems alright.

https://www.ticalc.org/archives/files/fileinfo/421/42163.html

NL OS

More screensavers, backgrounds, etc..

https://www.ticalc.org/archives/files/fileinfo/122/12267.html

Nostub Explorer

Comprehensive file explorer, but it doesn’t like BASIC programs.

https://www.ticalc.org/archives/files/fileinfo/209/20961.html

Orage Shell

Very fancy and nice looking shell with various functions and icons. Reminds me of the Amiga for some reason.

https://www.ticalc.org/archives/files/fileinfo/339/33918.html

PC emulation (potential)

Whether these emulators support operating systems for these computers is unknown; it must be looked into further. PCs without meaningful OSes are not included.

Sinclair ZX Spectrums – Tezxas

PCTools 0.97B patched

Patched version of an advanced file manager supporting plugins, nested folders, etc.

https://www.ticalc.org/archives/files/fileinfo/405/40506.html

PedroM 0.83

A very awesome looking GNU GPL adhering Unix-style OS. Feature filled, capable, and flexible. Has USB support. Also works on the 92+.

https://www.ticalc.org/archives/files/fileinfo/319/31951.html

PRAGOS

The obligatory clone of the classic Windows UI.

https://www.ticalc.org/archives/files/fileinfo/117/11759.html

PreOS

A reasonable kernel with various functions, such as “Crash protection”. Has a developer version.

https://www.ticalc.org/archives/files/fileinfo/350/35090.html

https://www.ticalc.org/archives/files/fileinfo/379/37939.html (developer)

Prosit 0.81.1

Great looking shell, but it doesn’t do much with existing programs. Practically functions as an OS.

https://www.ticalc.org/archives/files/fileinfo/105/10510.html

Punix

So far the kernel is being written, and user-space utilities and applications will follow.

This OS is highly comprehensive, detailed, authentic, and sufficient for serving as a Unix-like. Almost complete, but there are known build issues. Remarkable work for this calculator. Note: this is primarily aimed at the TI-92+
