Librascope developed this small, drum-based computer for engineering and education. With only 113 vacuum tubes and 1,450 diodes, it used conventional office power and required no air conditioning. Although difficult to program, it was the first computer for many organizations.
Physicist Stan Frankel, intrigued by small, general-purpose computers, developed the MINAC at CalTech in 1954. The Librascope division of defense contractor General Precision bought Frankel’s design, releasing the LGP-30 in 1956.
Used for science and engineering as well as simple data processing, the LGP-30 was a “bargain” at less than $50,000.
