A complete computer called the ALWAC 800 was constructed using magnetic logic, but it was not commercially successful.
The Elliott 803 computer used a combination of magnetic cores (for logic function) and germanium transistors (as pulse amplifiers) for its CPU.
William F. Steagall of the Sperry-Rand corporation developed the technology in an effort to improve the reliability of computers.
Magnetic amplifiers of the type here described meet the necessary requirements of reliability of performance for the combinations discussed.
Solid state semiconductors were able to increase their density according to Moore's Law, and thus proved more effective as IC technology developed.
