Small-Scale Experimental Machine - Wikipedia, the free encyclopedia The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby, was the first stored-program computer to run a program, on June 21, 1948. The SSEM was a very limited machine, apparently more for the purposes of testing the Williams tube and other hardware than for producing a practical computer. It was a serial machine, operating on one bit at the time. en.wikipedia.org /wiki/Small-Scale_Experimental_Machine   (431 words)

TIH - SSEM On June 21, 1948 the SSEM became the first stored-program machine to run a program and so claimed it's niche in the history of computing. The SSEM (aka: "the Baby") was a computer constructed at the University of Manchester to test the Williams-Kilburn Tube memory system in preparation for the construction of the Manchester Mark 1 computer. www.cs.ubc.ca /~hilpert/tih/SSEM   (57 words)

A Chronology of Digital Computing Machines (to 1952) The Enigma machine uses a series of disks ("rotors") with sets of 26 contacts wired so as to permute and repermute the alphabet; the sequence of rotors and their initial settings are changed from time to time, forming a key. The Albany machine is used to produce a set of astronomical tables; but the observatory's director is then fired for this extravagant purchase, and the machine is never seriously used again, eventually ending up in a museum. Zuse considers the machine a prototype; it doesn't have enough memory to be much use for the equation-solving problems that the DVL was mostly interested in. www.davros.org /misc/chronology.html   (8186 words)

Manchester Baby Simulator After this date, the experimental machine was expanded upon and led to the development of the Manchester Mark 1 and later the Ferranti computers. The machine was built primarily to test out the use of tubes as a storage device and is the first use of the Williams Tube as it later became known. In preparation for the 50th anniversary of the first program's execution, a replica of the original machine was built at Manchester by a team lead by Christopher Burton a member of the Manchester Computer Conservation Society. davidsharp.com /baby   (339 words)

50th Anniversary of the Manchester Baby computer From this Small-Scale Experimental Machine a full-sized machine was designed and built, the Manchester Mark 1, which by April 1949 was generally available for computation in scientific research in the University. The Small-Scale Experimental Machine, known as SSEM, or the "Baby", was designed and built at The University of Manchester, and made its first successful run of a program on June 21st 1948. The Mark 1 and the next three machines were all turned into commercial machines; the fifth, MU5, made a major contribution to the design of the ICL VME2900 series. www.computer50.org   (474 words)

EDSAC Encyclopedia Article, Definition, History, Biography EDSAC was the world's first practical stored program electronic computer, although not the first stored program computer (see the Small-Scale Experimental Machine). The machine, having been inspired by John von Neumann's seminal EDVAC report, was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. In 1951, Miller and Wheeler used the machine to discover a 79-digit prime—the largest known at the time. www.variedtastes.com /encyclopedia/EDSAC   (551 words)

The Manchester University Small-Scale Experimental Machine The Small-Scale Experimental Machine (SSEM) is the "official" name for the prototype Manchester Mark 1 as it existed when it successfully executed the world’s first stored computer program on 21st June 1948. In the case of the Control: while the machine is running the CI and PI appear on alternate lines of the Monitor, but if the machine is not running, then only the CI appears on all 32 lines. While the machine is not executing instructions, the PI line does not exist. www.cs.man.ac.uk /CCS/ssem/progref1.html   (2717 words)

wikien.info: Main_Page It was developed from the Small-Scale Experimental Machine or "Baby". This is the earliest known implementation of such index/base registers – an important innovation in computer architecture, unknown in other machines until the emergence of second-generation computers (approximately 1955–1964). Instructions were loaded into the machine by using paper tape. www.alanaditescili.net /index.php?title=Manchester_Mark_I   (287 words)

Programs for the Baby The Small Scale Experimental Machine, known as the Baby, was built at Manchester University in 1948. Finally, the scaling constant at 25 is encoded in the "LDN 28" instruction there, including the op code. With other scaling constants the program can achive higher precision and accuracy as well as handle larger angles at the cost of significantly increased run time. www.piercefuller.com /ssem   (426 words)

SSEMTalk.htm On June 21, 1948, the Manchester Mark I Prototype (also called the Small-Scale Experimental Machine or SSEM) became the first stored program computer to successfully execute a program. The SSEM was a small prototype - it had only 32 words of memory and seven instructions. A unique feature of the SSEM was its use of CRT memory. userpages.wittenberg.edu /bshelburne/SSEMTalk.htm   (250 words)

Manchester Celebrates the 50th Anniversary/Professor N. J. Lehmann From this Small-Scale Experimental Machine, known as SSEM, or the "Baby," a more powerful machine was designed and built - the Manchester Mark 1 - which by 1949 was being used for computation in scientific research in the University. This machine, in turn, was the basis of the Ferranti Mark1, arguably the world’s first commercially available general-purpose computer, with the first machine delivered in February 1951. It was conceived, in 1959, as a desktop machine, to be used as a personal computer by engineers, and was operational in 1963. www.ifip.or.at /newsletters/nl1q99/man_cel.htm   (815 words)

Baby’s 50th Birthday Celebrations. It was a single address machine, one instruction being held in one store location; 5 bits as an address and three bits for the function. A little more than a week later the run time of the machine had been extended to 52 minutes when it calculated the highest factor of 2 raised to the power 18. Following the success of the BABY machine work was immediately started on a much larger computer. myweb.tiscali.co.uk /davidpack/museum/transmit/baby.html   (1548 words)

Manchester Baby Computer This computer, the Small Scale Experimental Machine, included the stored-program concept, so that the Random Access Memory was used not only to hold numbers involved in calculations, but to hold the program instructions. It was called the "Small Scale Experimental Machine", but was soon nicknamed the "Baby". So the next step was to build a small computer around a CRT memory, to subject it to the "most effective and searching tests possible". www.computer50.org /mark1/new.baby.html   (1242 words)

EYEWITNESS@DIGITAL SUMMER 98 We were treated to an impressive two hour multimedia spectacular, using lighting effects, still and moving pictures on large screens, and live drama, recreating the moment in 1948 when Tom Kilburn and Freddie Williams successfully got the Small Scale Experimental Machine to work. Though I'd arrived without a ticket, I was given perhaps the best seat in the house - in the middle directly in front of the stage. Professor Kilburn then came onstage and gave his personal perspectives on the events leading up to June 1998. www.manchesteronline.co.uk /ewm/ds98/event02.html   (287 words)

2003 Projects in Simulation These particles will be subjected to thermal excitation, and if they are small enough may not be able to retain their magnetisation, resulting in data loss. In 1997, a software simulator of the SSEM was written for use in the programming competition which took place for the 50th anniversary of the Baby computer. The simulator was very useful for the competition, but the SSEM team was not able to release final details of the actual SSEM until after Andrew had left and M1SIM has never been brought up to date. www.cs.manchester.ac.uk /ugrad/projects/year03/sim.html   (2556 words)
