What is "ultrapin"

UltraPin is a Multi-Game pinball arcade game that holds 12 digital recreations of Williams Electronics real pinball games in a single pinball cabinet. UltraPin is built in a traditional style pinball cabinet to look and feel like a real pinball machine. It has two LCD screens, a 19 inch LCD for the back glass and DMD, and a 32 inch LCD for the playfield, and it uses Windows XP Embedded for its operating system.
