Tectoy Mega Net
From Sega Retro
Mega Net was an online service for Brazilian owners of the Sega Mega Drive, in the vein of Japan's Sega Meganet service. As with most Brazilian products with a relation to Sega, the service was started and maintained by Sega's Brazilian distributor Tectoy, and as such, it did not exist outside of Brazil.
Tectoy's Mega Net service began in late 1995, and required a proprietary Mega Net modem accessory to be inserted into the Mega Drive's cartridge slot. Unlike similar services across the world such as North America's Sega Channel, the Mega Net service allowed users to send and receive emails, "text chat" (a.k.a. instant messaging) and maintain a journal. It was also able to retrieve news from Tectoy regarding new game releases.
The Mega Net service was designed to be used in conjunction with the Mega Drive Keyboard.
