The NCR Century 100 was NCR's first all integrated circuit computer. 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. ==Peripherals== The 615-100 Series integrated a complete data processing system had 16KB or 32KB of short rod memory, 80-column card reader or paper tape reader, two 5MB removable disc drives, 600-line per minute printer. The system could be provided with a punched paper tape reader, or an external card reader/punch, and also allowed for the attachment of multiple 9 track 1/2 inch reel to reel magnetic tape drives. Two more disk drives could be attached to the system. The Century series used an instruction set with two instruction lengths: 4 bytes (32 bits) and 8 bytes (64 bits).
