This section of the Daystrom 046 consists of the multiplexer, logic cabinets, and auxiliary memory. The 046 was manufactured by Daystrom's La Jolla division and was the company's first product utilizing transistors and core memory. Daystrom guaranteed a 99 percent availability, which was demonstrated at Louisiana Power & Light's Sterlington Plant. This 046 is the second purchased by Louisiana Power & Light. It was installed at the Little Gypsy Power Plant in 1961 in LaPlace, La., and was the first computer to control a power plant from startup to shutdown.
