According to The Pinball Compendium 1982 to Present, this game started out with three other names and two other themes, as "Samurai", "High Noon", and "Gunslinger". Designer Mark Ritchie chose a new theme based on the "Mad Max" movies of the preceding years. The playfield will show the left inlane insert is #4 and the right inlane insert is #3, or it will show the left insert is #3 and the right insert is #4. We don't know the reason for this difference, but we note the lamp and switch matrix tables on pages 24 and 26 of the Manual in our Files Section have apparently been superceded by an unnumbered page at the end of that manual where the two tables are repeated, except the asmts for #3 and #4 have traded places. 'Road Kings' is one of three Williams games that went into production using System 11. All three games have incorrect schematics showing the same error by depicting placement of the flipper end-of-stroke switch on the wrong side of the coil. As far as we know, all games left the factory correctly wired for EOS. Only the schematics were incorrect. No Manual Amendments or Service Bulletins have been found that acknowledge or correct this error. For a correct drawing of EOSS placement, consult the schematic for Williams' 1986 'PIN�BOT' or subsequent Williams games.
