Other Operating Systems

Developers keep making operating systems to call their own. Maybe out of pure vanity we take pride of their programs or set of inter-related programs as an OS. The following list is in alphabetical order.


2/OS is a desktop environment for MS-DOS, compatible with Unix and Win32 applications. It runs on an i386 with 8 MB of RAM. There is a Lite version that only needs 4 MB of RAM.

AROS Research Operating System:

AROS Research Operating System is portable and free of charge desktop environment aiming at being compatible with AmigaOS for FreeBSD or Linux. It runs on at least 700 MHz with floating-point unit (FPU) and 256 MB of RAM.

Icaros Desktop 1.3.1 with Amiga 68K integration

Atari Running on Any Machine:

ARAnyM (Atari Running on Any Machine) is a virtual machine that can run 32-bit emulation of Atari ST, TT030 and Falcon including TOS, FreeMiNT, MagiC and applications for M68k microprocessor and Graphical Environment Manager (GEM).


EmuTOS is replacement for Atari TOS with GEM as its GUI. It supports the Atari Coldfire Project, also known as FireBee, which is an Atari computer clone.

Graphic Environment Operating System (8-bit):

GEOS (8-bit) or Graphic Environment Operating System (8-bit) is an 8-bit OS for Commodore 64 and other MOS Technology 6502 computers with a GUI that resembled Mac OS 5.x developed by Berkeley Softworks in 1986 (then GeoWorks, now Breadbox).

Graphic Environment Operating System (16-bit):

GEOS (16-bit) or PC/GEOS is a 16-bit version of GEOS (8-bit) as a Windows 95 replacement for older PCs.


KolibriOS — available in 16- and 32-bit — was forked from MenuetOS, but heavily scaled down. Its image comes with several video games and several emulators. It seems like a great OS for gaming.

MenuetOS is written in assembler and fits in a floppy. It needs mouse, i386, 32 MB of RAM and 1 MB Display Vesa 2.0+ LFB. I have not had a chance to use it yet although I have tested KolibriOS, which is based on MenuetOS.

MINIX is open source Unix-like OS written in C. It is the base of Linux distribution (distros). It supports various hardware configurations with minor changes on the kernel or installing it from its source code. Note that MINIX does not come with a GUI hence fully CLI.


MorphOS is an OS compatible with AmigaOS with a combination of open source and proprietary code, especially its kernel. It seems to be marketed as a replacement for Mac OS on hardware made in the past decade or so.

NewOS is an OS that is under development written in C, C++ and assembler. This OS can fit on a floppy. As per the developers, it is "mostly a kernel with a minimal amount of user space libraries and applications." This means plain CLI, no GUI. If you want to try it, you can run its binaries (located at /usr/local/i386-newos/bin) on FreeBSD, Linux, Mac OS X or Windows using Cygwin.


NitrOS-9 is a Linux-like OS based on OS-9 for TRS-80 CoCo, and Dragon 64. To run this OS you would need a floppy drive or loading it from mounted Linux, Mac or Windows CD-ROM.

ReactOS is a project to create an OS compatible with the Windows NT kernel, DOS, OS/2 and Java subsystems. According to its developing group, this system is 93.8% complete, current version 0.3.1. If there is an alternative/new OS that I would like to test is this one. I will see what I can do.



SkyOS is fairly POSIX-complaint, but proprietary, OS "built from scratch" by Robert Szeleney.

Visopsys (VISual OPerating SYStem), created by Andrew McLaughlin "from scratch", is a 32-bit Windows replacement with read-only support for ext2 and ext3 used by Linux and other Unix clones.

On a side note, I never stop thinking and processing information all around me. As such, one of the subjects that attracts me most (aside from technology and music) is human behavior, not limited to psychology and ethos of the individual and masses. Hence I usually read, study and write essays of my own. From all possible authors in this field, some of my favorites are (in order of interest) Nietzsche, Levinas and Kant. As such, I have published two science fiction books, in which I include my opinion on religion, sociology, psychology, politics, manipulation of the masses, media, science and various technologies.

Under the Thelian Sky, ISBN
             9781494232283, ASIN B00GTQBY04

In Under the Thelian Sky, mankind did not originate on Earth, but rather on Mars. When Mars could no longer sustain life, mankind had to escape and colonized Earth. Many years later, a study was written about the survival of mankind in Mars and its struggle in Earth led by Doctor Ajidan Edejem. We proved to be a species that has survived wars, slavery and other forms of abuse. All the while, the government controlled by "them" wants to keep everything quiet and even kill him for telling others about the unavoidable doom. Years before the extinction of life in Mars, the Thelian society was perfect, yet corrupted. Life was easy, yet difficult if you were different. For every good person, like Ahila Keinj who found peace in The Faith, there were many willing to destroy it all for gain while "they" controlled the fate of many. At the end, an outsider simply known as Operative Logger 9C56 tries to fight "them" and stop "their" manipulation of history and mankind.

You can get Under the Thelian Sky exclusively at Amazon — available on print (ISBN 9781494232283) and e-book (ASIN B00GTQBY04).

In The Daydreamer, Robert James is a normal New Yorker who wakes up one morning unsure what had happened in his life. He is accused of killing the woman he has always loved, but he remembers three possible realities. Which reality could be true? Has he dreamed these realities, seen this events or taken part of these strange acts? Is he a killer or is he being framed? Perhaps he knows the killer better than anyone else without realizing it.
