VCO Object

VCO Object arcade hardware was used by Sega for a brief period between 1981 and 1983. It was Sega's earliest attempt at creating hardware specifically designed for sprite scaling, something that would be widely used in Sega X Board and Sega Y Board hardware, and a handful of Sega System boards in between.

The hardware debuted with the release of Turbo, and is often known as "Turbo Hardware" because of this.

All VCO Object games rely on external LED displays for parts of the HUD. This means extra precautions must be taken when attempting to emulate VCO Object games.

List of VCO Object Games

Only three games make use of VCO Object hardware:

• Turbo (1981)
• Buck Rogers: Planet of Zoom/Zoom 909 (1982)
• SubRoc-3D (1983)
