Sega Mega-Tech is an arcade system developed by Sega Europe in 1989. It is based on Mega Drive/Genesis hardware, and more or less identical.[1] The Mega-Tech uses a unique pinout, allows 8 cartridges to be plugged in at once, and powers a second monitor for game selection and additional information.

In Megatech games your coins buy you time to play the game, how you perform in the game does not matter, you can die and start a new game providing you still have time, likewise you can be playing well and run out of time if you fail to insert more coins. This is the same method Nintendo used with their Playchoice 10 system.

The BIOS screen is based around SMS hardware, with an additional Z80 and SMS VDP chip not present on a standard Genesis. SMS games run on Megatech in the Genesis's SMS compatability mode, where the Genesis Z80 becomes the main CPU and the Genesis VDP acts in a mode mimicing the behavior of the SMS VDP. A pin on the carts determines which mode the game runs in.[2]

The PCB for 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 released in Europe, Australia, and Asia (including Japan), but not in North America.[1]
