No Binding. Zustand: Very Good. [ENGINEERING RESEARCH ASSOCIATES] Photograph and engineering documents for an experimental Magnetic Drum Memory system Engineering Research Associates, St Paul MN, circa 1948 Gelatin silver print, on glossy paper stock, 217 x 278mm [together with:] 8 sheets of engineering drawings, reproduced from manuscript originals, 216 x 279mm Very good condition: photograph creased around the edges but the image in excellent condition; drawings near fine: age toned and brittle, with rust marks and creases from a paper'clip An outstanding survival: a group of original mimeographed engineering drawings, and a presentation photograph of the assembled magnetic drum memory system, dating from the very early years of the development of this crucial component of electronic digital computing. Magnetic drum memory was one of the first practical forms of electronic computer memory, using a rotating drum coated with a magnetic material to store data and instructions. The original idea dates back to the 1930s, but it was brought into use in electronic digital computing by Engineering Research Associates (ERA) in the period 1946-1950. ERA had its origins in wwii us Navy during code-breaking. After the War a group of engineers and scientists in the group Communications Supplementary Activity - Washington (CSAW) sought investors for the development of specialist code-breaking machinery, ending up in St Paul, Minnesota, in a disused glider factory. Their specialism was magnetic drum storage, and in 1947 the Navy commissioned a stored-program electronic digital computer, eventually made public as the ERA 1101. Through 1947-48 ERA issued a number of technical papers on the development of magnetic drum storage; the system was made more widely known with the publication of their classic handbook on digital computers, High-Speed Computing Devices (1950). From the limited information in the caption of the photograph here, we can date the image and engineering drawings to the period between the prototype work of 1947 and the finished commercially available drums of 1950. Drum memory influenced early computer architecture, including instruction sequencing and memory management. A particularly important case is IBM, where initial contact with era led to the development of the ibm 650, the company's first mass-produced electronic digital computer.

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! The IBM 305 RAMAC, publicly announced on September 13, 1956, was the first commercial computer that used a moving head hard disk drive magnetic disk storage for secondary storage. RAMAC stood for 'Random Access Method of Accounting and Control'. Its design was motivated by the need for real time accounting in business. The first RAMAC to be used in the US auto industry was installed at Chrysler's MOPAR Division in 1957. It replaced a huge tub file which was part of MOPAR's parts inventory control and order processing system. The 305 was one of the last vacuum tube computers that IBM built. The IBM 350 disk system stored 5 million 8-bit 7-bits plus 1 odd parity bit characters. It had fifty 24-inch diameter disks. Two independent access arms moved up and down to select a disk, and in and out to select a recording track, all under servo control. Average time to locate a single record was 600 milliseconds. Several improved models were added in the 1950s. The IBM RAMAC 305 system with 350 disk storage leased for $3,200 per month in 1957 dollars, equivalent to a purchase price of about $160,000. More than 1000 systems were built.
