Developer Jake Steinburger, also called “UnmappedStack,” has launched a UNIX-like working system written from scratch — but able to enjoying id Software program’s traditional first-person shooter Doom: TacOS.
“TacOS [is] my from-scratch OS with it is personal kernel written in C and meeting,” Steinburger explains of the mission. “TacOS is a UNIX-like kernel which is ready to run Doom, amongst varied different smaller userspace packages. It has issues like a VFS [Virtual Filesystem], scheduler, TempFS [Temporary Filesystem], gadgets, context switching, digital reminiscence administration, bodily web page body allocation, and a port of Doom. It runs each on actual {hardware} (examined on my laptop computer) and within the Qemu emulator.”

In use, TacOS will likely be acquainted to anybody who has expertise of UNIX, Linux, or different POSIX-style working techniques. It boots right into a textual console that gives the standard instructions for interacting with the filesystem, which is specified by the normal UNIX model. In addition to these primary instructions, there’s additionally a port of Doom Generic — an fashionable variant of the id Software program’s 1993 first-person shooter Doom, primarily based on the corporate’s later open-source launch.
TacOS builds atop PotatOS, Steinburger’s earlier 64-bit kernel mission that in flip was a successor to SpecOS. “I ended my earlier mission, SpecOS, as a result of mission being fairly damaged and having code left from once I knew actually nothing about kernel growth. PotatOS is a rework now that I perceive extra,” Steinburger wrote on the time, “and whereas it is nonetheless not excellent, I can confidently say that it is already quite a bit higher.”
The supply code for the working system and its kernel can be found below the MPLv2 license. (📷: Jake Steinburger)
“Please observe that TacOS is a passion toy OS and isn’t full sufficient for actual utilization,” Steinburger says of the currently-available launch — echoing, knowingly or in any other case, Linus Torvalds’ 1991 announcement of his Linux mission, wherein he described his work as “only a passion [which] will not be large {and professional} like GNU.” In contrast to TacOS, Linux couldn’t play Doom on the time of its announcement — primarily as a result of id Software program would not launch the sport till two years later.
TacOS is out there on GitHub below the Mozilla Public License Model 2, full with directions on compiling the working system and operating it within the Qemu emulator.
