NCR Century 100

The NCR Century 100 was NCR's first all integrated circuit computer built in 1968. It was one model in a line of computers called the "Century" series (initially the 100, 200, and 300). All logic gates were created by wire-wrapping NAND gates together to form flip-flops and other complex circuits. The console of the system had only 18 lights and switches and allowed entry of a boot routine, or changes to loaded programs or data in memory. A typewriter console was also available.
