Code-named “Magic,” this was HP’s first MS-DOS personal computer (PC). It was one of the earliest mass-produced computers to use a touch-screen, which allowed for user-friendly applications. It was not IBM-PC compatible but the HP-150 was one of the earliest computers in the United States to use 3 ½” floppy disk drives, which soon became a standard. It sold for $2,795. The HP-150 was also a movie star, appearing in the film Real Genius.
