DOCS (Display Operator Console Support) was a software package for IBM mainframes by CFS Inc., enabling access to the system console using 3270-compatible terminals. [1]
Computer operators communicated with IBM mainframe computers using an electro-mechanical typewriter-like console that came standard on most IBM 360 and 370 computer, except a few upper end models that offered video consoles and the Model 20 which came standard without a console.
Mainframe computers or mainframes are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing. They are larger and have more processing power than some other classes of computers: minicomputers, servers, workstations, and personal computers.
A typewriter is a mechanical or electromechanical machine for writing characters similar to those produced by printer's movable type. Typically, a typewriter has an array of keys, and pressing one causes a different single character to be produced on the paper, by causing a ribbon with dried ink to be struck against the paper by a type element similar to the sorts used in movable type letterpress printing. Commonly, a separate type element corresponds to each key, but the mechanism may also use a single type element with a different portion of it used for each possible character. At the end of the nineteenth century, the term typewriter was also applied to a person who used a typing machine.
The majority of smaller and less expensive IBM 360s and 370s came equipped with these ruggedized Selectric keyboard devices. The Selectric was a major step up from the teletypes (TTY) associated with Unix and smaller systems, but still clunky. The video consoles provided with certain models were not considered particularly user friendly, and they ignored two thirds of IBM's mainframe market, DOS and its VSE descendants.
Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
DOCS replaced or supplanted the typewriter interface with a video screen. In practice, it worked a little like present-day instant messenger programs (ICQ, QQ, AIM, Adium, iChat, etc.), with a data entry line at the bottom and messages scrolling in real time up the screen. The commands were otherwise identical.
The user interface (UI), in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.
ICQ is a cross-platform instant messaging and VoIP client. The name ICQ derives from the English phrase "I Seek You". Originally developed by the Israeli company Mirabilis in 1996, the client was bought by AOL in 1998, and then by Mail.Ru Group in 2010.
Tencent QQ, also known as QQ, is an instant messaging software service developed by the Chinese tech giant Tencent. QQ also offers services that provide online social games, music, shopping, microblogging, movies, and group and voice chat software. The logo of the software is a winking penguin wearing a red scarf. It is the world's 7th most visited website, according to Alexa.
DOCS was available for DOS, DOS/VS, DOS/VSE, and came packaged with third party operating systems, such as EDOS from The Computer Software Company, later acquired by Nixdorf.
Wincor Nixdorf was a German corporation that provided retail and retail banking hardware, software, and services. Wincor Nixdorf was engaged primarily in the sale, manufacture, installation and service of self-service transaction systems, retail banking equipment, lottery terminals, postal terminals, software and services for global financial and commercial markets. In October 2015, Wincor Nixdorf’s cashless Payments unit was carved out of the group and started trading independently under the name of AEVI. On August 15, 2016, through the merger of Wincor Nixdorf and Diebold Inc., Diebold Nixdorf was formed as an international technology and services company.
The product ran under several DOS-related platforms:
Several vendors offered DOCS as part of their OS:
DOCS was developed by CFS, Inc. of Brookline, Massachusetts at the Kayser-Roth data center in Whitman, Massachusetts. Dick Goran wrote the video interface. Leigh Lundin wrote the operating system interface and transcript recorder.
Brookline is a town in Norfolk County, Massachusetts, in the United States, and is a part of Greater Boston. Brookline borders six of Boston's neighborhoods: Brighton, Allston, Fenway–Kenmore, Mission Hill, Jamaica Plain, and West Roxbury. The city of Newton lies to the west of Brookline.
A data center or data centre is a building, dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems.
Whitman is a town in Plymouth County, Massachusetts, United States. The population was 14,489 at the 2010 census. It is notable as being the place where the chocolate chip cookie was invented.
DOCS required a dedicated partition. With DOS having only three partitions and DOS/VS seven, giving up a partition to DOCS placed a crimp in practicability.
Leigh Lundin designed Fx, a pseudo-partition that relieved the user from relinquishing a working partition. Fx appeared in the DOS/VS version of SDI's Grasp as F0.
DOCS was sold in North America by CFS, Inc, Brookline, Ma.
For overseas sales, CFS engaged in both mail order and local vendors. The product was also embedded in third party operating system packages, such as EDOS and vDOS.
z/VSE is an operating system for IBM mainframe computers, the latest one in the DOS/360 lineage, which originated in 1965. Announced Feb. 1, 2005 by IBM as successor to VSA/ESA 2.7, then-new z/VSEwas named to reflect the new "System z" branding for IBM's mainframe product line.
Hercules is a computer emulator allowing software written for IBM mainframe computers and for plug compatible mainframes to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems programmer.
VM is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules emulator for personal computers.
Disk Operating System/360, also DOS/360, or simply DOS, is a discontinued operating system for IBM mainframes. It was announced by IBM on the last day of 1964, and it was first delivered in June 1966. In its time, DOS/360 was the most widely used operating system in the world.
The IBM 2741 is a printing computer terminal that was introduced in 1965. Compared to the teletypewriter machines that were commonly used as printing terminals at the time, the 2741 offers 50% higher speed, much higher quality printing, quieter operation, interchangeable type fonts, and both upper and lower case letters.
Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM-compatible mainframes which are compatible with the larger IBM mainframe computers. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space. However, they sacrificed performance and were not as dependable as mainframe-class hardware. These products have been popular with mainframe developers, in education and training settings, for very small companies with non-critical processing, and in certain disaster relief roles.
The history of operating systems running on IBM mainframes is a notable chapter of history of mainframe operating systems, because of IBM's long-standing position as the world's largest hardware supplier of mainframe computers.
Virtue is a virtual session manager running under IBM's VM.
DUCS was a teleprocessing monitor from CFS Inc. It was one of two early local teleprocessing packages for IBM's DOS/VSE environment. DUCS provided an interface and access method for programmers to 'talk' to monitors. Such access methods later became known as APIs.
Westi was one of two early local teleprocessing packages for IBM's DOS/VSE environment. Westi stood for Westinghouse Terminal Interactive. Westi provided an interface and access method for programmers to 'talk' to monitors and handle data entry. Such access methods later became known as APIs and the handlers a form of transaction processing.
Edos was an operating system based upon IBM's original mainframe DOS. The name stood for extended disk operating system.
The Spooler was a systems software operating system package that provided spooling facilities for the IBM System/370 running DOS/VS, DOS/VSE environment, and IBM System/360 running DOS/360 or retrofitted with modified DOS/360, such as TCSC's EDOS. Other venders offering The Spooler as part of their OS were Amdahl, Fujitsu, Hitachi, Magnuson, and RCA.
The IBM Kanji System was announced in 1971 to support Japanese language processing on the IBM System/360 computers. It was later enhanced by the support of IBM System/34, IBM 5550 and DOS/V.
GRASP was a systems software package that provided spooling facilities for the IBM/370 running DOS/VS or DOS/VSE environment, and IBM/360 running DOS or retrofitted with modified DOS.
POWER was an IBM operating system enhancement package that provided spooling facilities for the IBM System/360 running DOS/360 or retrofitted with modified DOS/360. Upgrades, POWER/VS and POWER/VSE were available for and the IBM System/370 running DOS/VS and DOS/VSE respectively. POWER is an acronym for Priority Output Writers, Execution processors and input Readers.
The IBM Selectric typewriter was a highly successful model line of electric typewriters introduced by IBM on 31 July 1961.
The IBM 9370 systems were "baby mainframe" midrange computers, released 1986 at the very low end of, and compatible with System/370.
The IBM Enterprise System/390 was the third generation of the System/360 instruction set architecture. The first ESA/390 computer was the Enterprise System/9000 (ES/9000) family, which were introduced in 1990. These were followed by the CMOS System/390 mainframe family in the mid-1990s. These systems followed the IBM 3090, with over a decade of follow-ons. The ESA/390 was succeeded in 2000 by the 64-bit z/Architecture in 2000.
