List of transistorized computers

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a list of digital computers using discrete transistors as their primary logic elements, also known as transistorized computers. Transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until hybrid and monolithic integrated circuits displaced them in the 1970s. The list is organized by operational date or delivery year to customers. Computers announced, but never completed, are not included. Some very early "transistor" computers may still have included vacuum tubes in the power supply or for auxiliary functions.
