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.
