The NCR 315 Data Processing System, released in January 1962 by NCR, [1] is a second-generation computer. All printed circuit boards use resistor–transistor logic (RTL) to create the various logic elements. It uses 12-bit slab memory structure using magnetic-core memory.

Up to 16 of these unique magnetic card handlers can be operated on-line in an NCR 315 Com-puter System. With its speed, power, and flexibility, this new external mem- ory device opens a whole new approach to economical electronic processing.

Rod memory is one of the many variations on magnetic core memory that attempts to lower costs by automating its manufacturing. It was introduced by NCR in 1964 as part of the NCR 315 RMC computer, RMC for "rod memory computer". It was also used in their Century line.

The NCR 315 computer has been taught to understand and carry out instructions that have been written in COBOL, the "near English" pro- gramming language. The COBOL Translator, available with the 315, will greatly simplify your programmers "teaching" job.

The brochure presents the NCR 315 as a low cost, high performance computer. The front cover folds out to 3 pages with a color photograph of people working at the NCR 315 on the inside. The front and back covers have a repetitive NCR pattern in blac.

NCR 315-RMC — The NCR 315 RMC, released in July 1965 by NCR Corporation, was the first commercially available computer to employ thin film memory. This reduced the clock cycle time to 800 nanoseconds.

NCR 315 . This is the first NCR Solid State Mainframe with CRAM, (Card Random Access Memory).

The brochure presents the NCR 315 as a low cost, high performance computer. The front cover folds out to 3 pages with a color photograph of people working at the NCR 315 on the inside. The front and back covers have a repetitive NCR pattern in black and white, with the front fold out pages showing a broad black band across the white background.
