1957: CDC founded by William Norris in the Twin Cities as a spin-off of Engineering Research Associates. (2, 125-126)

1960: CDC 1604 introduced (2, 125)

CDC 160A, early minicomputer (2, 125)
- The spin-off of CDC included Seymour Cray.
- Cray had worked for UNIVAC on the Navy Tactical Data System (NTDS).
- NTDS was a transistorized on-board machine for Navy ships.
- Based on NTDS experience, Cray designed the CDC 160 as an I/O processor for the CDC 1604.
- CDC produces a commercial version, the 160A, for a price of $60,000.
- It's a minicomputer, and a market opens up.

CDC 6600, first supercomputer (JCB)
- 160 evolves to peripheral processors for the 6600.

Short summary (2, 172-173)
- 1972: Seymour Cray leaves to found Cray Research and built the CRAY-1 supercomputer.
- PLATO (3): interactive, graphical system for education.
