'Sega's Out Run hardware was released in 1986 with the driving game OutRun. It is a successor to their Hang-On hardware, making it the second in the "Super Scaler" series of pseudo-3D arcade hardware. It was succeeded by the Sega X Board in 1987.

The Out Run hardware, like the Hang-On hardware, has specifications similar to those of the System 16, with the addition of a second 68000 processor and a separate video board which allowed for an extra graphics layer for the road as well as sprite scaling capabilities. The Out Run hardware can do everything the Hang-On hardware can do, but its processors are clocked higher (allowing for quicker calculations) and the board can draw two roads (the Hang-On hardware can only draw one). At the time, the Out Run hardware was a very powerful but expensive arcade board, with arcade operators advised to charge twice as many credits than for regular arcade machines.

Three made use of the hardware, all of which are driving games. However, only OutRun and Turbo OutRun are truly for this hardware, as Super Hang-On was also released for the Hang-On hardware in a mostly identical form.
