ES EVM - Hardware Models and Technical Details

Hardware Models and Technical Details

The first subseries (ЕС ЭВМ-1) of the ES EVM, released in 1969-1978, included the models 1010, 1020, 1030, 1040 and 1050, which were analogous to System/360 and operated at 10-450 kIPS, and the more rare and advanced versions, incompatible with the IBM versions: 1022, 1032, 1033 and 1052. The electronics of the first models were based on TTL circuits; the later machines used ECL design. ES 1050 had up to 1M RAM and 64-bit floating point registers. The fastest machine of the series, ES 1052, developed in 1978, operated at 700 kIPS.

The second subseries, released in 1977-1978, included the models 1015, 1025, 1035, 1045, 1055 and 1060, analogous to System/370 and operated at 33 kIPS - 1.050 MIPS. ES 1060 had up to 8M RAM.

The third subseries, released in 1984, were analogous to System/370 with some original enhancements, and included 1016, 1026, 1036, 1046 and 1066. ES 1066 had up to 16M RAM and operated at 5.5 MIPS. The fourth subseries had no direct IBM analogs and included 1130, 1181 and 1220. The last machine in the series, ES 1220, released in 1995, supported a number of 64-bit CPU commands, 256M RAM and operated at 7 MIPS, but was not successful; only 20 such machines were ever produced, and in 1998 the whole production of ES mainframes was stopped.

Famous quotes containing the words details, technical, hardware and/or models:

    Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.
    Jeanne Elium (20th century)

    When you see something that is technically sweet, you go ahead and do it and you argue about what to do about it only after you have had your technical success. That is the way it was with the atomic bomb.
    J. Robert Oppenheimer (1904–1967)

    A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.”
    Brenda Ueland (1891–1985)

    Grandparents can be role models about areas that may not be significant to young children directly but that can teach them about patience and courage when we are ill, or handicapped by problems of aging. Our attitudes toward retirement, marriage, recreation, even our feelings about death and dying may make much more of an impression than we realize.
    Eda Le Shan (20th century)
