Sega Saturn
Operating Systems (Hitachi SH-2)
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.

WonderSwan Color - OSwan
Linux
to port linux enough to run a stripped down X server and X mosaic
A hypothesized port by a 90s internet tech company, presumably made to sell a “Internet capable saturn” software package. If only they actually did it. Still theoretically possible.
“Saturn OS” (fake?)
Sega and Microsoft apparently formed a partnership by January 1994 to work on an OS
While it appears this was simply a misunderstanding or playing-up of their partnership, it could have possibly been originally a legitimate project, that either fell through or got downgraded.

Saturn-you Word Processor
It comes with the software, called EGWORD
Not actually an OS, of course, but supported writing to floppies and such. There also appears to be an active English translation project.

Stock BIOS
What came with the console. Not super “operating” like, but pretty advanced interactivity for 1994.
TNKernel SATNKernel port
SATNKernel is a port of the TNKernel real-time kernel version 2.6
This is merely a kernel, but it provides some functionality and operability akin to an actual system.
Internet
Modern NetLink and PlanetWeb(!!!) revival
Optional Equipment - For Accessing NetLink Zone, Surfing the Internet
A modern solution for making the NetLink work, supporting all of it’s previous functions. Web browsing included. Best is to get the most recent PlanetWeb disc (for the NetLink Zone) maybe, and the most recent homebrew browser offerings.

Version & Revision Guide
For general information, see the Game Console Revisions Overview.
Versions
There are two versions of this console, arranged chronologically.
“Saturn (Model 1; MK-80000)” (1995-1996)
These Saturns are easily identified by their power and reset buttons, which are angled and oval shaped. Furthermore, they have a CD access light. Two controller ports are up front, and on the back is the AC in, AV out, and a communication port for the networking this console has. On this version, the AC in is oblong shaped. Some say these have a reasonably superior video quality output, but whether this is due to revisions of the motherboard is unknown.
“Saturn (Model 2; MK-80000A/80001)” (1996-1998)
Unlike the Model 1 Saturns, these systems have completely circular reset and power buttons. Furthermore, the CD access light has been removed. At the back, the AC in has been changed to a “8” or “pinched in” shape, which means cables from the Model 1 won’t work on these (although Model 2 AC cables work fine on the Model 1). While these systems have two model numbers used, the only differences between them are internal. Some say that these consoles have a faster disc reader. Furthermore, several revisions of these models may have issues with game compatibility or video interference. Lastly, these consoles are a lot easier to modchip.
Revisions
There is 1 revision set within the Saturn (Model 1; MK-80000), and 4 revision sets within the Saturn (Model 2; MK-80000A/80001).
Saturn (Model 1; MK-80000) revisions:
“VA0-3” (1995-1996)
The only motherboard revision for the Model 1s, but important to note, as board swaps can put these types of boards in the Model 2, theoretically. Many internal and technical changes that do not impact the user in any way. To identify these, look for a digit ranging from 0-3 in the 3rd or 4th spot of a Saturn serial number. For details, check the Saturn PSU guide link marked with “Serial help”.
Saturn (Model 2; MK-80000A/80001) revisions:
“VA4-7” (1996)
This is simply the earlier revision set of the Model 2 which does not have any real problems known with it. Probably the best one, or at least the 2nd best one of the Model 2s. Identified with a digit from 4-7 in the 3rd or 4th spot of the serial.
“VA8” (1996)
DO NOT PURCHASE
These boards have only one change from the 4-7s, but it is significant. There are reports that these consoles experience noticeable video interference issues, and they also appear to be a common revision for Model 2s. Because of this seemingly high frequency, this revision may be to blame for the Model 2’s reputation of supposedly poorer video. Thus, it is best to avoid these. Identified with an 8 in the 3rd or 4th spot of the serial.
“VA10-11” (1997/98?)
DO NOT PURCHASE
These boards don’t have the video output issues of the VA8, but they do however, have certain 68k code issues which lead to incompatibility in several games. For this reason, it is also worthwhile to avoid these boards. Identified by a letter A or B in the 3<rd or 4th spot of the serial.
“VA12-14” (1997/98?)
The last boards made for the Sega Saturn. There appear to be no reports about these boards having some sort of problem, plus they’re newer systems. Identified by a letter D or F in the 3rd or 4th spot of the serial.
All recommendations couldn’t be assigned. Best answer is any Model 1, plus a 4-7/12-14 Model 2.
