It is a successor to 1985's [[Sega Hang-On hardware]], making it the second in Sega's Super Scaler series of pseudo-3D arcade hardware. It was succeeded by [[Sega X Board]] in 1987.

Sega OutRun hardware, like 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. OutRun Hardware can do everything Hang-On Hardware can do, but its processors are clocked slightly higher (allowing for more quicker calculations) and the board can draw two roads (Hang-On Hardware can only draw one). At the time, OutRun Hardware was a very expensive arcade board, with arcade operators advised to charge twice as many credits than for regular arcade machines.

Sega OutRun hardware
Manufacturer: Sega
Release Date RRP Code

Sega OutRun hardware is an arcade system created by Sega in 1986, and was first used for the driving game OutRun. It is a successor to 1985's Sega Hang-On hardware, making it the second in Sega's Super Scaler series of pseudo-3D arcade hardware. It was succeeded by Sega X Board in 1987.

Sega OutRun hardware, like 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 and sprite scaling graphics. OutRun Hardware can do everything Hang-On Hardware can do, but its processors are clocked higher (allowing for quicker calculations) and the board can draw two roads (Hang-On Hardware can only draw one). At the time, OutRun Hardware was a very expensive arcade board, with arcade operators advised to charge twice as many credits than for regular arcade machines.

Only four games made use of the hardware, all of which are driving games. Realistically however, only OutRun and Turbo OutRun are true OutRun Hardware games - the other two were also released for Hang-On Hardware and are mostly identical in both forms.
