HITAC (HItachi Transistor Automatic Computer)[1] is the designation for the majority of Hitachi large and midrange computer models spanning several decades. The HITAC 301, released in May 1958, was Hitachi's first fully-transistorized computer model. Earlier Hitachi computers made use of semiconductors known as parametrons.[2]
