APh Technological Consulting was an engineering firm based in Pasadena, California. It was formed in 1974 as a limited partnership by two California Institute of Technology (Caltech) students, Glenn Hightower and John Denker. [1] (APh is an abbreviation for applied physics. [2])

In 1976, APh was hired by Mattel to help design the Intellivision system. They also developed the operating system and the first games. [3]

Several members of APh left in 1982 and started Cheshire Engineering after a dispute over profits from developing Mattel's "M Network" line of Atari 2600 games. [4]
