During the late 1980s and throughout the 1990s, Sega produced a number of video game console kiosks for in-store display. The idea being that potential customers could play a demo of a game and get a feel for the system before a purchase. Kiosks of this nature have been around since the days of the Atari 2600 and continue to be used today.
For most of the 90s Sega were supporting at least two home consoles in parallel, be it the Sega Master System, Sega Mega Drive, Sega Game Gear or Sega Saturn, and often produced kiosks to accomodate multiple systems. With the dawn of the Sega Dreamcast standards were created in the form of the Dreamcast Kiosk, in which every kiosk looked and behaved largely the same regardless of where one was spotted in a specific region.
Earlier kiosks are almost bespoke units and can vary dramatically from store to store. Kiosks were only sold to retail outlets, so many units have been disposed of during the last twenty years, in turn making them collectors' items. This page lists all Sega kiosks known to have existed before the Dreamcast.
Saturn kiosk from 1998-ish.
Common during the early 90s, this grey kiosk designed for the Sega Mega Drive uses a Demo System DS-16 unit to allow uses to switch between six cartridges on the fly.
A larger variant of the above, designed to accommodate the Game Gear too.
Presumably released around the same time ast the above (or slightly later), this is a non-switch variant which demonstrates two-player games.
A kiosk built specifically for the Sega Saturn. Likely from around 1995.
The orange/blue kiosk is surprisingly one of the most common Sega kiosks in North America, despite being released during or after 1996 when the company was in decline. This is a very basic kiosk designed to accomodate either the Sega Saturn or Sega Mega Drive (or Genesis in this case). At the time of release multi-carts and demo discs were widely available, so a cartridge switching device was not seen as a requirement. By default, artwork from Sonic 3D: Flickies' Island was included on the bottom half of the cabinet.
A grey post-1991 cabinet meant to house both a Mega Drive and Master System.
