The Sega Mega-Tech was a 16-bit arcade system based on the Mega Drive hardware, they are more or less identical. Its operation ability is similar to Nintendo's PlayChoice-10, where the credits bought give the user a playable time period rather than lives (usually 1 minute per credit), and can switch between games during playtime.

The Mega-Tech also includes the ability to display to a second monitor, which contains a list of the games installed in the machine and also displays instructions for controlling the game, 1 or 2 player information, and a short synopsis of each game. The second monitor also displays the time left for playing.

The Sega Mega-Tech was developed by Sega Europe in 1989. A few things were omitted, such as the expansion hardware allowing for Mega CD or 32X as these were not developed at this point, so would not likely be offered as an arcade expansion.

Since the machine was basically a Mega Drive with timer control for arcade operations, porting games to the Mega-Tech was an easy task and so many games were released, most of them popular titles. The ability was also added for the machine to play Sega Master System titles, though fewer Master System titles were ported than Mega Drive titles.

The Sega Mega-Tech system was replaced in 1993 by its successor, the "Mega-Play", a JAMMA based system.
