BATCH-11/DOS-11, also known simply as DOS-11, is a discontinued operating system by Digital Equipment Corporation (DEC) of Maynard, Massachusetts. The first version of DOS-11 (V08-02) was released in 1970 and was the first operating system to run on the Digital PDP-11 minicomputer. DOS-11 was not known to be easy to use even in its day and became much less used in 1973 with the release of the RT-11 operating system.

Features

DOS-11 included: [1]

DOS-11 came with XXDP, a diagnostics and monitor program for the PDP-11. Like other Digital operating systems, DOS-11 also had a FORTRAN-IV (Ansi-66) compiler. FORTRAN-IV was not supported on PDP-11 systems with less than 12K of memory. DOS-11 systems running in 8K and 12K configurations ran a limited version of the MACRO-11 Assembler (PAL-11R in overlaid form).

The DOS-11 operating system kernel was one file called MONLIB.LCL. The LCL extension was the acronym for LInked Core Image Library (or LICIL). An LICIL could be stored on any type of media that the DOS-11 operating system was distributed on (disk, DECtape, punched tape or magnetic tape). When the LICIL file was installed (Hooked) onto a disk drive as a contiguous file, the monitor library name is changed to MONLIBCIL which could then be booted. The CIL extension was the acronym for Core Image Library. Core, was the term for the core memory systems common to the PDP-11. A Core Image Library could be created with the CILUS (Core Image Library Update and Save) program. A MONLIBCIL typically contained the resident monitor (RMON), the keyboard command routine, device drivers, EMT routines, the clock routines and the transient monitor.

Legacy

DOS-11 was used to compile and install early versions of the RSTS-11 and RSTS/E operating systems however it is an ancestor to the RSX-11 family of operating systems.[ citation needed ]

PDP-8 First commercially successful minicomputer

The PDP-8 is a 12-bit minicomputer that was produced by Digital Equipment Corporation (DEC). It was the first commercially successful minicomputer, with over 50,000 units being sold over the model's lifetime. Its basic design follows the pioneering LINC but has a smaller instruction set, which is an expanded version of the PDP-5 instruction set. Similar machines from DEC are the PDP-12 which is a modernized version of the PDP-8 and LINC concepts, and the PDP-14 industrial controller system.

PDP-11 Series of 16-bit minicomputers

The PDP-11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer.

TECO, short for Text Editor & Corrector, is both a character-oriented text editor and a programming language, that was developed in 1962 for use on Digital Equipment Corporation computers, and has since become available on PCs and Unix. Dan Murphy developed TECO while a student at the Massachusetts Institute of Technology (MIT).

History of operating systems Aspect of computing history

Computer operating systems (OSes) provide a set of functions needed and used by most application programs on a computer, and the links needed to control and synchronize computer hardware. On the first computers, with no operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral devices like printers and punched paper card readers. The growing complexity of hardware and application programs eventually made operating systems a necessity for everyday use.

RSX-11

RSX-11 is a discontinued family of multi-user real-time operating systems for PDP-11 computers created by Digital Equipment Corporation. In widespread use through the late 1970s and early 1980s, RSX-11 was influential in the development of later operating systems such as VMS and Windows NT.

RT-11 is a discontinued small, low-end, single-user real-time operating system for the Digital Equipment Corporation PDP-11 family of 16-bit computers. RT-11, which stands for Real-Time, was first implemented in 1970 and was widely used for real-time systems, process control, and data acquisition across the full line of PDP-11 computers. It was also used for low-cost general-use computing.

BOS/360

BOS/360 was an early IBM System/360 operating system.

OS/8 was the primary operating system used on the Digital Equipment Corporation's PDP-8 minicomputer.

Peripheral Interchange Program (PIP) was a utility to transfer files on and between devices on Digital Equipment Corporation's computers. It was first implemented on the PDP-6 architecture by Harrison "Dit" Morse early in the 1960s. It was subsequently implemented for DEC's operating systems for PDP-10, PDP-11, and PDP-8 architectures. In the 1970s and 1980s Digital Research implemented PIP on CP/M and MP/M.

RSTS/E Computer operating system

RSTS is a multi-user time-sharing operating system, initially developed by Evans Griffiths & Hart of Boston, and acquired by Digital Equipment Corporation for the PDP-11 series of 16-bit minicomputers. The first version of RSTS was implemented in 1970 by DEC software engineers that developed the TSS-8 time-sharing operating system for the PDP-8. The last version of RSTS was released in September 1992. RSTS-11 and RSTS/E are usually referred to just as "RSTS" and this article will generally use the shorter form.

TOPS-10 System is a discontinued operating system from Digital Equipment Corporation (DEC) for the PDP-10 mainframe computer family. Launched in 1967, TOPS-10 evolved from the earlier "Monitor" software for the PDP-6 and PDP-10 computers; this was renamed to TOPS-10 in 1970.

IBM 1130 16-bit IBM minicomputer introduced in 1965

The IBM 1130 Computing System, introduced in 1965, was IBM's least expensive computer at that time. A binary 16-bit machine, it was marketed to price-sensitive, computing-intensive technical markets, like education and engineering, succeeding the decimal IBM 1620 in that market segment. Typical installations included a 1 megabyte disk drive that stored the operating system, compilers and object programs, with program source generated and maintained on punched cards. Fortran was the most common programming language used, but several others, including APL, were available.

Disk Operating System/360, also DOS/360, or simply DOS, is the discontinued first member of a sequence of operating systems for IBM System/360, System/370 and later 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.

VSI BASIC for OpenVMS is the latest name for a dialect of the BASIC programming language created by Digital Equipment Corporation (DEC) and now owned by VMS Software Incorporated (VSI). It was originally developed as BASIC-PLUS in the 1970s for the RSTS-11 operating system on the PDP-11 minicomputer. It was later ported to OpenVMS, first on VAX, then Alpha, and most recently Integrity.

PDP-15

The PDP-15 was the fifth and last of the 18-bit minicomputers produced by Digital Equipment Corporation. The PDP-1 was first delivered in December 1959 and the first PDP-15 was delivered in February 1970. More than 400 of these successors to the PDP-9 were ordered within the first eight months.

RADIX 50 or RAD50, is an uppercase-only character encoding created by Digital Equipment Corporation (DEC) for use on their DECsystem, PDP, and VAX computers.

MACRO-11 is an assembly language with macro facilities for PDP-11 minicomputers from Digital Equipment Corporation (DEC). It is the successor to PAL-11, an earlier version of the PDP-11 assembly language without macro facilities.

TSS/8 is a discontinued time-sharing operating system co-written by Don Witcraft and John Everett at Digital Equipment Corporation in 1967. DEC also referred to it as Timeshared-8 and EduSystem 50.

The PDP-9 Disk Monitor is a discontinued operating system released by Digital Equipment Corporation for their PDP-8 line of mini-computers. The minimum hardware requirements consisted of a ASR 33 teletype, 3 cycle data break, and a mass storage option of a DF32 disk sub-system or a TC01 DECtape unit, with later releases the additional option of using a RF08 disk drive. The distribution media was on paper tape, a common means of data storage for computers of that era. The included user programs consisted mainly of modified versions of the paper tape software library distributed by DEC for their PDP-8 family of small computers, much of this was exported to the TSS-8 and MS/8 operating systems.

Interactive Application System (IAS) was a DEC operating system for the PDP-11. It was a fork from RSX-11D.
