The Sega Neptune was a two-in-one Mega Drive/Genesis and 32X console which Sega planned to release in 1994 or 1995. The proposed retail price for the unit was US$200.
Sega had admitted how expensive and problematic the 32X was,so it was decided to make a combined version of the Mega Drive/Genesis and 32X; however, by the time a prototype came out, the Sega Saturn was ready for release. Sega felt that consumers would not be interested in the Sega Neptune, so the project was scrapped. There are several prototypes, and at least one was declared to work.
Electronic Gaming Monthly used the Sega Neptune as an April Fool's Joke in its April 2001 issue. The issue included a small article in which the writers announced that Sega had found a warehouse full of old Sega Neptunes, and were selling them on a website.
