The game uses digital score displays and electronic sound controlled by Intel i4040 CPU boards. Reportedly, there is no year of manufacture or copyright date indicated on the backglass, playfield, or in the game manual(s). Previously, we had shown the year as 1977 but the game flyer carries the SEGA logo in a 'scripted' style of font that was used until approximately mid-1976. Therefore, we have changed the year to 1976, which is when their last EM games were made. It is the only SS pinball machine we have from Sega that carries this style of logo. All their other SS games carry the later style, making 'Rodeo' the apparent first SS pinball machine Sega made. The 4-player version is Sega Enterprises' 1979 'Rodeo' with a different playfield layout.
