Description

This is a black and white image of a 3D I/O device constructed under .i.MIT: Project MAC:Crystal Ball. The ball is against a white background with a cord going off to the right edge of image. The top of the ball is a clear half dome top. The Crystal Ball was used as a three-step rate control to provide a natural easy control over the rotation of a three dimensional object viewed on the screen. If desired the Crystal Ball could be used in any way that the programmer desired. Important early user interface: The designers used a DEC 330 scope connected to an IBM 7094 for computer aided design. Stamped on verso side is "894 2285". Written on verso side in blue ink is "5".
