Logicon "Computer" Desktop Calculator

Image Courtesy Dr. Norman M. Martin

Programmable desktop electronic calculator designed for in-house engineering use by Logicon, Inc. of Redondo Beach, California. CRT Display. Learn-mode programming. Core memory for register and program storage. First prototype operational early to mid-1965. Machine never became a product -- it was designed and manufactured (somewhere between two and six were apparently made) strictly as a tool to help with engineering calculations within Logicon.

The photo above is of the original operating prototype of the calculator.
