# List of early third generation computers

This list of early third generation computers, tabulates those computers using monolithic integrated circuits (ICs) as their primary logic elements, starting from small-scale integration CPUs (SSI) to large-scale integration CPUs (LSI). Computers primarily using ICs first came into use about 1961 for military use. With the availability of reliable low cost ICs in the mid 1960s commercial third generation computers using ICs started to appear.
The fourth generation computers began with the shipment of CPS-1, the first commercial microprocessor microcomputer in 1972 and for the purposes of this list marks the end of the "early" third generation computer era. Note that third generation computers were offered well into the 1990s.
The list is organized by delivery year to customers or production/operational date. In some cases only the first computer from any one manufacturer is listed. Computers announced, but never completed, are not included. Computers without documented manual input (keyboard/typewriter/control unit) are also not included.

## Commercial computers (1965-1971)

This table of commercial 3rd generation computers has been constructed by merging of several lists of computers offered from February 1965, the date of the shipment of the first commercial 3rd generation computer, thru 1971 inclusive and then finding reliable sources as to the generation of the models listed and the associated dates.
