MAINFRAME HISTORY
Dr. Gene Amdahl, chief architect of the System/360, was once referred to as the “Father of the System/360” by IBM’s Chairman and CEO, Thomas J. Watson Jr. In fact, Fred Brooks, the project manager of the System/360, said Amdahl “maintained architectural consistency across six engineering teams by sheer intellectual force and banging on the table.”

He left IBM in 1970 and founded the Amdahl Corporation to build computers compatible with hardware and software of the System/370. He cleverly called his systems the Amdahl 470 Series. They were faster and cheaper than IBM’s comparable computers, and by 1979, Amdahl had more than $200 million in revenue, and 22% of the mainframe market. He died at 92 in Palo Alto, CA on November 2015.

MAINFRAME HISTORY
When it was first widely used almost 99 years ago, 80 column punched cards held nearly all of the world's known information for almost half a century.

Very quickly, after the announcement of the IBM mainframe, the IBM 29 card punch was announced on October 14, 1964, the newest version of a device first developed 83 years earlier. The punch (and its companion, the IBM 59 card verifier) were used to record and check information in punched cards. The IBM 29 card punch remained in the product catalog until May 1984.

MAINFRAME HISTORY
At one time, the name UNIVAC was synonymous with computers for most Americans. Although IBM clearly held the number one position in the computer industry by the mid 1950s, the name most familiar to the general public was UNIVAC, primarily because it was used to predict the outcome of the presidential election in 1952 on national TV. It was also well known as the first computer used by the U.S. Census Bureau.

Needless to say, IBM took off big-time with the introduction of the System/360 in 1964; to the point that they owned 95+ percent of the computer market by the late 1970s.

MAINFRAME HISTORY
The IBM 3270 display terminal, often referred to as a “green screen," was designed and developed by IBM's Kingston, NY laboratory. It was first revealed to the public on April 9, 1971. Later, in 1979, the color 3279 display was designed and developed in IBM’s Hursley labs in the U.K.

The 3270 terminal was unique in two primary ways. First, the 3270 didn’t use the standard ASCII character set; rather it used the EBCDIC character set (a legacy from the time when mainframes were programmed via punched cards. Second, the 3270 used block mode communication instead of character mode.
By the end of the 1990s, most 3270 terminals had been replaced with emulator software.

“As you know, mainframe ownership is a serious financial commitment. In addition to the initial investment, a large percentage of the total cost of these super computers goes toward maintenance.” https://lnkd.in/dC-3pq6a
