https://www.ticalc.org/archives/files/fileinfo/138/13833.html
Aegis Operating System
Has “36 parts” such as programs/apps and pictures. Newer than most of the OSes on this list, being made in 2012.
https://www.ticalc.org/archives/files/fileinfo/450/45033.html
AlphaCS
It is password protected and very secure
A fast and small little GUI for program launching. This requires zStart for launching, however.

https://www.ticalc.org/archives/files/fileinfo/457/45745.html
Anova
An alpha build of a windows-inspired shell with some programs on the front. Looks at least a bit interesting due to the desktop icon integration.
https://www.ticalc.org/archives/files/fileinfo/417/41786.html
Aperate
An OS emulator with resizable windows, command prompt, program manager, and multitasking. A bit advanced for these calculators.
https://www.ticalc.org/archives/files/fileinfo/406/40632.html
Apple Pro 2
All information is in the supplied .txt file. Appears to be a password protected program to run IONs and such.
https://www.ticalc.org/archives/files/fileinfo/125/12578.html

A clone of a basic Unix shell. Functionality unknown.
https://www.ticalc.org/archives/files/fileinfo/236/23600.html

Bash
A Linux clone that has Windows file conventions for some reason.
https://www.ticalc.org/archives/files/fileinfo/254/25450.html
Black Eagle Shell GUIs
Various GUIs for the “Black Eagle Shell”. They all look a bit interesting, and the fact that it’s a pack of 4 makes this stand out somewhat.
https://www.ticalc.org/archives/files/fileinfo/361/36125.html
BURNiNATOR
A BASIC shell with a prank program and “three menus”.
https://www.ticalc.org/archives/files/fileinfo/395/39599.html

Another Windows ripoff that apparently sucks and is very broken.
https://www.ticalc.org/archives/files/fileinfo/339/33992.html
Calcbox
A fluxbox-inspired shell with a cursor and menus. Probably looks very esoteric.
https://www.ticalc.org/archives/files/fileinfo/410/41084.html
CalcMac
A simple clone for the TI-83, but it may also work on the TI-84?
https://www.ticalc.org/archives/files/fileinfo/428/42809.html
CalcOS
Reminds me of a ticket machine or television news station for some reason. BASIC shell.
https://www.ticalc.org/archives/files/fileinfo/302/30265.html

https://www.ticalc.org/archives/files/fileinfo/376/37646.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.
Nintendo Game Boy (no color) – Ti-Boy SE Beta 0.2.05
Core 1.0
By including file transfer and a reminder program, this OS has managed to stand out.
https://www.ticalc.org/archives/files/fileinfo/410/41087.html
Cos 1 Standard
Has a calendar, and password protection… and a GUI!
CrunchyOS 0.6
Crunchy doesn't contain it internally as other shells do
May not work on new 83s or 84s, due to an LCD driver code issue. Otherwise, a simple shell for viewing programs in a list, as long as they have a shell header.
https://www.tiwizard.com/downloads/crunchy-os/
https://www.ticalc.org/archives/files/fileinfo/325/32507.html
CSX (TI-83+ only?)
because CSX, pongOS, etc was made for the TI-83+

https://www.ticalc.org/archives/files/fileinfo/349/34973.html
Cygnus A & B
Two variants of this OS, with one being like DOS, and the other being like your typical icon-less Windows clone.

Looks kind of cool, and is apparently faster than Black Eagle.
https://www.ticalc.org/archives/files/fileinfo/410/41077.html
Doors CS 7.2
Run any BASIC or ASM program or game
A shell that runs on top of the existing “OS” these calculators run. Known as the best shell that is not just a straight up OS running on the calculator in place of the original OS.
https://www.ticalc.org/archives/files/fileinfo/430/43068.html
DreamSoft OS
This one has an instant messenger and word processor! Astonishing.
https://www.ticalc.org/archives/files/fileinfo/181/18158.html
Emu8x
Although it is slow, it allows me to write TI-86 Basic programs
A Z80 emulator that can run a TI-81, 82, 83, 85, or 86. Worthy of inclusion outside of the “PC emulators” generic category.

https://www.ticalc.org/archives/files/fileinfo/278/27884.html (13.0.5)

https://www.ticalc.org/archives/files/fileinfo/390/39042.html (1.0 P)

https://www.ticalc.org/archives/files/fileinfo/121/12143.html
Global OS
This is in a demo state, but it is claimed to be 98% more stable, implying it mostly functions. Something in the menus visible is about a “Game emulator”, which piques the interest.
https://www.ticalc.org/archives/files/fileinfo/310/31035.html
Great Operate 1.1
Has a “notebook”, but no “annoying password protection”.
https://www.ticalc.org/archives/files/fileinfo/129/12990.html

Another OS with various features, such as a loader, playing WAVs, varying font styles, etc. As in, it’s not just a glorified shell on top of TI-OS.
https://web.archive.org/web/20070530054043/http://forum.reaktix.com/viewtopic.php?pid=11
