===Atari 800===
[[File:DIN-5 Diagram.svg|left|65x65px]]
The [[Atari 8-bit computers|Atari 800]] introduced separate Chroma/Luma output in late 1979. The signals were put on pin 1 and 5 of a 5-pin 180-degree [[DIN connector]] socket. Atari did not sell a monitor for its 8-bit computer line, however.<ref name="8-bit FAQ"/>

===Commodore 64===
[[File:DIN-8 Diagram.svg|left|65x65px]]
The [[Commodore 64]] released in 1982 (with the exception of the earliest revisions using a 5-pin video port) also offers separate chroma and luma signals using a different connector. Although [[Commodore Business Machines]] did not use the term ''S-Video'' as the standard did not formally exist until 1987, a simple adapter connects the computer's LCA (luma-chroma-audio) 8-pin DIN socket to a S-Video display, or an S-Video device to the Commodore 1702 monitor's LCA jacks.<ref name="8bitguy20180511">{{Cite video |url=https://www.youtube.com/watch?v=BpXFB8ZEH30#t=9m38s  |archive-url=https://ghostarchive.org/varchive/youtube/20211211/BpXFB8ZEH30| archive-date=2021-12-11 |url-status=live|title=Commodore History Part 3 - The Commodore 64 (complete)|date=2018-05-11 |last=Murray |first=David |publisher=YouTube |series=The 8-Bit Guy |time=9:38 |access-date=2018-05-12}}{{cbignore}}</ref>

===4-pin mini-DIN===
[[File:MiniDIN-4 Diagram.svg|left|65x65px]]
The four-pin [[mini-DIN connector]] is the most common of several S-Video connector types. The same mini-DIN connector is used in the [[Apple Desktop Bus]] for Macintosh computers. Apple Desktop Bus cables can be used for S-Video in a pinch.<ref>{{cite web|url=https://support.apple.com/kb/TA35008?locale=en_US|title=Macintosh: S-Video Port Confused with the ADB Port|access-date=2015-04-27|archive-date=2016-05-12|archive-url=https://web.archive.org/web/20160512155657/https://support.apple.com/kb/TA35008?locale=en_US|url-status=dead}}</ref><ref>{{cite book|url=https://books.google.com/books?id=4yXVZYMd-q4C&q=adb%20s-video&pg=PA86|title=Compression for Great Digital Video: Power Tips, Techniques, and Common Sense|isbn=9781578201112|last1=Waggoner|first1=Ben|year=2002|publisher=Taylor & Francis }}</ref><ref>{{cite book|url=https://books.google.com/books?id=KH0rBgAAQBAJ&q=adb%20s-video&pg=PA451|title=A Practical Guide to Video and Audio Compression: From Sprockets and Rasters to Macro Blocks|isbn=9781136036101|last1=Wootton|first1=Cliff|date=28 April 2005|publisher=CRC Press }}</ref> Other connector variants include seven-pin locking ''dub'' connectors used on many professional S-VHS machines, and dual Y and C [[BNC connector]]s, often used for S-Video [[patch panel]]s. Early Y/C video monitors often used phono ([[RCA connector]])  that were switchable between Y/C and composite video input. Though the connectors are different, the Y/C signals for all types are compatible.

The mini-DIN pins, being weak, sometimes bend. This can result in the loss of color or other corruption (or loss) in the signal. A bent pin can be forced back into shape, but this carries the risk of the pin breaking off.

These plugs are usually made to be plug-compatible with S-video, and include optional features, such as [[component video]] using an adapter. They are not necessarily S-video, although they can be operated in that mode.

===7-pin mini-DIN===
[[Image:Pseudo miniDIN-7 Diagram.svg|left|64px|7-pin plug diagram]]

Non-standard 7-pin mini-DIN connectors (termed ''7P'') are used in some computer equipment (PCs and Macs). A 7P socket accepts, and is pin compatible with, a standard 4-pin S-Video plug.<ref name="pin7"/> The three extra sockets may be used to supply [[Composite video|composite (CVBS)]], an RGB or YPbPr video signal, or an [[I²C]] interface. The [[pinout]] usage varies among manufacturers.<ref name="pin7">{{cite book |title=Video demystified: a handbook for the digital engineer |author=Keith Jack |publisher=Newnes |year=2007 |isbn=9780750678223 |url=https://books.google.com/books?id=Kp5J7G8kXN4C&q=Video%20demystified%3A%20a%20handbook%20for%20the%20digital%20engineer.%20Newnes.%20p.%2069.&pg=PA69}}</ref><ref>{{cite book |title=ATI Radeon 7 pin SVID pinout|url=https://pinoutguide.com/Video/svideo_7pin_pinout.shtml}}</ref> In some implementations, the remaining pin must be grounded to enable the composite output or disable the S-Video output.

Some Dell laptops have a [[S/PDIF|digital audio output]] in a 7-pin socket.

===8-pin mini-DIN===

The 8-pin mini-DIN connector is used in some [[ATI Radeon]] video cards<ref name="8-pin">{{cite web | title=ATI Radeon 8-pin audio / video VID IN connector pinout | author=Pinouts.Ru | year=2017

===9-pin Video In/Video Out===

[[Image:MiniDIN-9 Diagram.svg|65px]]

9-pin connectors are used in graphics systems that feature the ability to input video as well as output it.<ref>ATI Radeon: Using Video in and Video out.</ref><ref>{{cite web|title=ATI Radeon 9 pin VIVO pinout|url=http://pinouts.ru/Video/radeon_vivo_pinout.shtml}}</ref> Again, there is no standardization between manufacturers as to which pin does what, and there are two known variants of the connector in use. As can be seen from the diagram above, although the S-Video signals are available on the corresponding pins, neither variant of the connector will accept an unmodified 4-pin S-Video plug, though they can be made to fit by removing the key from the plug. In the latter case, it becomes all too easy to misalign the plug when inserting it with consequent damage to the small pins.
