Commodore Amiga

The Amiga is a family of personal computers  sold by Commodore  starting in 1985. The original model was part of a wave of 16 and 32 bit computers that featured 256KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio over 8-bit systems.

Although early Commodore advertisements attempt to cast the computer as an all-purpose business machine, especially when outfitted with the Amiga Sidecar PC compatibility add-on, the Amiga was most commercially successful as a home computer, with a wide range of games and creative software.

Cancelled games
Only one Sonic game was ever made for this system, and the game never made it into public release due to disagreements between Sega and U.S. Gold.
