High Quality Content by WIKIPEDIA articles! The NCR Century 100 was NCRs first all integrated circuit computer. 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. If you had a the punched paper tape read, you could have an external card reader/punch. The system also allowed for the attachment of multiple 9 track 1/2 inch reel to reel magnetic tape drives. You could attach at least 2 more disk drives to the unit. 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. To start the machine you entered a hexadecimal boot strap code by setting the rotary switches. This would read a set of four boot cards that loaded the B1 operating system programs from the boot disc.
