of Radar Scope was restructured for Donkey Kong. The Radar Scope hardware, originally inspired by the Namco Galaxian hardware, was designed for a large number of enemies moving around at high speeds, which Donkey Kong does not require, so the development team removed unnecessary functions and reduced the scale of the circuit board. The gameplay and graphics were reworked for updated ROM chips, and the existing CPU, sound hardware, and monitor were left intact. The character set, scoreboard, upper HUD display, and font are almost identical to Radar Scope, with palette differences. The Donkey Kong hardware has the memory capacity for displaying 128 foreground sprites at 16x16 pixels each and 256 background tiles at 8x8 pixels each. Mario and all moving objects use single sprites, the taller Pauline uses two sprites, and the larger Donkey Kong uses six sprites. Hiroshi Yamauchi thought the game was going to sell well and phoned to inform Arakawa. Nintendo of America's distributors, Ron Judy and Al Stone, brought Arakawa to a lawyer named Howard Lincoln to secure a trademark. The game was sent to Nintendo of America for testing. The sales manager disliked it for being too different from the maze and shooter games common at the time, and Judy and Lincoln expressed reservations over the strange title. Still, Arakawa adamantly believed that it would be a hit. American staff began translating the storyline for the cabinet art and naming the characters. They chose "Pauline" for the Lady, after Polly James, wife of Nintendo's warehouse manager Don James. Arakawa suggested that the name of "Jumpman", a name originally chosen for its similarity to the popular brands Walkman and Pac-Man, be changed to "Mario" in likeness of Mario Segale, the landlord of the original office space of Nintendo of America. These character names were printed on the American cabinet art and used in promotional materials. Donkey Kong was ready for release. Stone and Judy convinced the managers of two bars in Seattle, Washington, to set up Donkey Kong machines. The managers initially showed reluctance, but when they saw sales of $30 a day—or 120 plays—for a solid week, they requested more units. In their Redmond headquarters, a skeleton crew composed of Arakawa, his wife Yoko, James, Judy, Phillips, and Stone gutted 2,000 surplus Radar Scope machines and applied the Donkey Kong conversion kits imported from Japan, consisting of motherboards, power supplies, and marquee graphics.
