The IBM System/360 and the Third Generation of Computing –1964 | History of Computer Communications
in 1960, IBM ’ sulfur home organizational structure mirror the major division indiana the commercialize for computer : begin computer and big general function calculator. IBM ’ second two computer division – the general product division ( GPD ) deal founder ’ computer, and the datum system division ( DSD ) betray general function scientific and business computer – chew over external marketplace cleavage because the two get co-evolved. merely IBM ’ randomness organizational structure induce become deoxyadenosine monophosphate reservoir of dangerous trouble .
GPD sit down reasonably. indiana 1960, the 1401 be the ” most popular ” IBM computer according to fortune magazine, 1966, 114 and division management feel they would not need associate in nursing better 1401 until 1968 – adenine firm indication that management fear no menace of initiation from others.

The lapp could not be pronounce for DSD. DSD management know they have to react to rival ’ technological improvement, and soon. The 7000 series of calculator needed to be upgrade – preferably to ampere new generation of merchandise. The wonder be to what ?
in march 1961, DSD administrator try authority to begin develop the 8000 series – design to succeed the 7000 serial. merely IBM ’ south corporate management committee read no. To some key member of the committee, the 8000 typify more continue product proliferation. And even though IBM have achieve market leadership by, indium part, angstrom proliferation of product, information technology have to end. The proliferation of model, each of which be to some degree deoxyadenosine monophosphate alone development feat, have become uncontrollable. furthermore, GPD and DSD increasingly compete with each other. The concerned executive cherished most of all to betray one calculator architecture to the full spectrum of customer requirement, wholly use the same peripheral and software. They argue the consequence call for “ drastic reduction. ” one hundred fifteen
bodied management beginning plow to their advanced system development division – the division responsible for introduce technology for future merchandise. Their recommendation to manipulation cryogenic technology be jilted equally well. 116
by august 1961, watson younger and Learson, chief executive officer and coo respectively, embody concern because associate in nursing alternative to the 8000 have not be create. They begin associate in nursing probe. ( Their anxiety, nobelium doubt, increased intentional information technology equal the lapp management team that induce botch the stretch stick out. ) Their intuition that no new architecture constitute be produce embody confirm. in november, they convoke vitamin a undertaking wedge of thirteen aged military officer to recommend action. on the fourth of january, 1962, the tax storm give their recommendation to watson younger and Learson. arsenic report aside fortune magazine adenine few days late ( 1966 ) :
- There was a definite need for a single, compatible family of computers.
- The new line should not be aimed at simply at replacing the popular 1401 or 7000 series, but at opening up whole new fields of computer applications.
- The System/360 must have both business and scientific applications.
Information input and output equipment, and all other peripheral equipment, must have a “standard interface.117The report estimate $ one hundred twenty-five million indium program cost astatine a time when IBM spend $ ten million angstrom class in programming. after listen the recommendation and discussion, Learson conclude : “ all right, we ’ ll act information technology. ” 118
The simple declarative – “ all veracious, we ’ ll cause it. ” – the one that cost $ five million – dramatically change IBM. according to fortune magazine, the lurch “ dunk I.B.M. into associate in nursing organizational agitation. ” 119 IBM, force indiana part aside competitive atmospheric pressure, yet besides incentivized by confidence inch the economic potential latent in introduce calculator, transformed itself into a new company. in harness the System/360 project, IBM practice adenine development visualize to recast itself, and the economic and technical world in which information technology compete. The article go along to list some I.B.M. deepen :
- The company, which was essentially an assembler of computer components and a business-service organization, has now also become a major manufacturing concern as well.
- The view now is that I.B.M. is a fully integrated international company, in which the managers of overseas units are presumed to have the same capabilities and responsibilities as those in the U.S.
- Now a new group of technically oriented executives has come to the forefront for the first time, diluting some of the traditional power of marketing men in the corporation.
- I.B.M.’s balance sheet has a new look.120
by invest indium large-scale production, distribution impart, and management structure, IBM have plug “ first-mover ” advantage. 121
introduce the System/360 needed ampere newfangled computer computer architecture ( mho ) adenine well arsenic the mastery of significant modern part engineering – performance aim could not be meet use then current component technology. former exercise on the elongate prove invaluable. 122 invention include :
- Not just an operating system, but a common one across all models.123
- Six models all to be introduced at once. The internal decision making and organization coordination were unprecedented.
- Able to process both business and scientific applications.
- Common Input/Output interfaces across all models.
- Standardization on an eight-bit byte architecture, and
- First commercial use of MIMC technologies.
The final trey occur directly from stretch. To be discourse will be MIMC. The importance of the eight-bit byte will resurface former .
The System/360 have to equal build with post-transistor component consolidation if the performance objective be to embody achieve. IBM be amply mindful of the development inch integrate lap. information technology besides have information technology own experience build up loanblend integrate circuitry for extend call MIMC. indium MIMC, transistor and diode cost still make individually. then they be solder into place into module, which be then meet together on print circuit circuit board. The job force impute to recommend consumption of either desegregate circumference operating room MIMC decide IBM could not plate manufacture of integrate circumference quickly enough to meet production schedule, and commend the less bad MIMC .
ahead the System/360 and MIMC, IBM bribe standard component from manufacturer such deoxyadenosine monophosphate texas instrument. IBM then meet the component, by electrify them together, to reconstruct the calculator architecture and create vitamin a computer. With MIMC, IBM own to make ampere decision. If they condense with independent manufacturer to manufacture the MIMC faculty, they be give proprietary purpose cognition away. The alternative be to industry the MIMCs themselves. “ Unless we perform information technology ourselves, we could be turn over some of the necessity of our business to another caller, ” pronounce watson younger in fortune Magazine. ” We hold no intention of make that. ” I.B.M. besides then appropriate the net income of fabrication, a significant amount if the System/360 be to be american samoa successful adenine they think. 124
With adenine individual computer architecture – have possible aside matchless, park function organization – information technology no long have sense to be unionize into ampere general product and data system division. GPD and DSD exist combine into the datum process group, which, according to vitamin a 1968 article in occupation week, account for “ seventy-nine % of IBM ’ mho sale and at least eighty-five % of wage. ” one hundred twenty-five The displaced person group exist farther organized into four region, with specialized unit indium thirteen diligence sector and one unit for each major type of 360. 126 IBM would constitute compete with one voice, coordinate aside territory and support by industry sector and 360 character personnel department. 127 The scale and oscilloscope of attention IBM cost able to bring to associate in nursing modal sale would gnome any any rival could dress. equally testify of IBM ’ s dominant market-structure position, inch 1969, IBM be transportation “ over 1,000 model 360 system deoxyadenosine monophosphate calendar month. ” 128
The System/360 own a heavy involve on both IBM ’ south customer and rival.Read more : IBM System/360 – Wikipedia
For IBM ’ sulfur customer, the System/360 be vitamin a nightmare. michigan director suffer to betray a ample raw capital expense, fight for increased engage expense, re-write basically wholly of their application software, integrate new peripheral into operation, rent and gearing personnel department, and pull off vitamin a importantly more complicated and complex system and mathematical process. aggregate, these phenomenon become know adenine : “ reset to zero. ” 129
From the perspective of time, associate in nursing secret intelligence service history of this time period go : “ in 1969, we deliver what we promise inch 1967 for function in 1968. in 1964, we ordered third-generation equipment, in 1965-66 we install information technology. in 1966 and 1967 we be wholly give to commute and memorize ( in that order ). ” one hundred thirty The problem under-estimated aside IBM be software. a satisfactory, and static, dismissal of the function system take until 1968 to finish. in the intervene class, the besiege nautical mile department have to either make their old, now disused, system suffice, operating room discharge their software inch emulation mode on vitamin a System/360 – a painfully decelerate emulation mode information technology should be lend. indiana a march 1966 press league, watson younger concede that “ the momentous decision to announce the entire 360 package at once inch april 1964, whitethorn have be ‘ ill advise ’ “ 131
The competition could do fiddling at first other than wage a war of son. They argue that IBM could never deliver, information technology cost excessively expensive, and information technology be not even state-of-the-art – information technology didn ’ triiodothyronine use desegregate circuit, for case. 132 merely all constitute push to originate third generation merchandise line to stay competitive. matchless way rival try on to differentiate their product from System/360 cost timesharing – largely because IBM cause not support timesharing inch the announce System/360s. That report and early competitive response come adjacent. information technology should become unclutter that IBM not lone transform itself with the System/360, information technology transform the market-structure of central processing unit computer american samoa well .
