The Century Series represents a new chapter in electronic data processing and incorporates the most modern technological developments.

We spent years designing and perfecting the Century Series of computers. For all levels of users. For both business and scientific applications. And for easy, low-cost installation.

A compatible family of computers. The Century Series will meet your requirements today and tomorrow. You can increase capacity and power as your needs change. No need to start over again. And no expensive reprogramming.

Great advancements in computer technology are incorporated in all members of the family. Their internal memories utilize thin film, short rods. Offering speed in the 800 nanosecond range. Yet automated manufacturing techniques have made this ultra-fast memory lower cost than slower core memory.

Expandability! All Century computers have it. You can add more disc units with 108 or 180 kc transfer rates and eight- million character capacities. Card Random Access Memory (CRAM) units each with a capacity of 125 million characters. Magnetic tape units with transfer rates up to 240 kc. 3000 LPM printers. MICR sorter/readers. OCR readers. Punched card and tape equipment. Remote on-line devices.

Sophisticated software! No other computer in the same price range as any Century computer can offer as much. Compilers, operating systems, applied programs and utility routines. All written, tested and ready-to-go for all members of the family. Programming languages: COBOL, FORTRAN and NCR's own NEAT/3. You'll appreciate the completeness of the Century operating system. The monitor section, for example, can completely schedule a Century computer's operation. Programs are loaded and automatically executed in the desired sequence based on priority, date or special conditions.

NEAT/3, a language with built-in simplicity, incorporates simple English instructions with powerful tools that enable the computer to generate its own program. Complicated logic and coding are eliminated because flexible procedural instructions and pre-programmed major computer functions are combined in one language.

Get the complete story of the Century. There's much more to tell about the Century Series that gives unequalled per- dollar performance.

Open House in Rancho Bernardo, CA on September 21, 1969

These pictures were taken at an Open House in Rancho Bernard, CA on September 21, 1969.  The corporate executives were coming out for a visit so they made it into a general Open House. I was still at the Hawthorne facility so I did not make it to the Open House, but I visited frequently as the first product they started manufacturing was the 615-100.  At the time I was the Unit Manager for that system.

Some of the pictures are associated with the wire wrap process. We ended up with at least 14 of the Gardner - Denver machines, and I think it was even more than that. The back panels were the heart of the systems. The max size was 5 rows of 88 slots each, with 24 pins per slot. I got way too much experienced at making hand wire wrap changes!

Note the general emptiness on the floor. The plant did not open until March of 1968, and they were still transitioning products down from Hawthorne. The products consisted of the 615-100, 615-200, 621 (Communications) and 653 (CRAM).

There are some more system oriented pictures. I believe the units are specially configured 615-100's, but some of them could have been early 615-200's.  The primary reason I think they are 100's is because of the pictures of the power cabinet. I designed the AC Distribution and the 615-100 just used two legs of a three pole breaker (70A each).  Those look exactly like I remember the ones for the 615-100.

Part of the pictures include some of the components of the system. Shown are the making of the console, power supplies, and the rod memory planes and arrays. I believe the unit with the 2-row back panel is a 621.

The rest show 653 CRAM cards and magazines, unfinished Common Trunk cables, and some of our metal capabilities. Eventually the machining and sheet metal work transferred to Wichita.
