MMDF – Introduction

MMDF, the Multichannel Memorandum Distribution Facility, is a mail transfer agent (MTA), a computer program designed to transmit e-mail. It was originally developed at the University of Delaware in the late 1970s, and provided the initial means of operating CSNet, the predecessor to NSFnet. It grew in popularity throughout the 1980s, and was selected by [...]

MUMPS – History

MUMPS was developed by Neil Pappalardo and colleagues in Dr. Octo Barnett’s animal lab at Massachusetts General Hospital (MGH) in Boston during 1966 and 1967. The original MUMPS system was, like Unix a few years later, built on a spare DEC PDP-7. Octo Barnett and Neil Pappalardo were also involved with MGH’s planning for a [...]

Starlink Project – History

From its beginning, the project aimed to cope with the ever-increasing data volumes which astronomers had to handle. A 1982 paper exclaimed that astronomers were returning from observing runs (a week or so of observations at a remote telescope) with more than 10 Gigabits of data on tape; at the end of its life the [...]

Comparison of BSD operating systems – Introduction

Berkeley Software Distribution (BSD) series of Unix variants. The three most notable descendants in current use are FreeBSD, OpenBSD, and NetBSD, which are all derived from 386BSD and 4.4BSD-Lite, by various routes. Both NetBSD and FreeBSD started life in 1993, initially derived from 386BSD, but in 1994 migrating to a 4.4BSD-Lite code base. OpenBSD was [...]

Polyhedra DBMS – Polyhedra Release History

* 1991 Development started. * 1993 Polyhedra 1.0: first commercial release of an in-memory Relational DBMS (RDBMS). * 1995 Ported to Windows and Linux. * 1996 Polyhedra 2.0: added hot standby configurations for use in applications needing high availability. First port to an RTOS (pSOS) * 1997 Polyhedra 3.0: new in-memory data storage engine, for [...]

Alpha 21164 – History

First silicon of the Alpha 21164 was produced in February 1994, and the OpenVMS, Digital UNIX and Windows NT operating systems were successfully booted on it. It was sampled in late 1994 and was introduced in January 1995 at 266 MHz. A 300 MHz version was introduced in March 1995. The final Alpha 21164, a [...]

DEC Alpha – Introduction

Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC), designed to replace the 32-bit VAX complex instruction set computer (CISC) ISA and its implementations. Alpha was implemented in microprocessors originally developed and fabricated by DEC. These microprocessors were most prominently [...]

Itanium – History

HP-UX Operating System

Development: 1989–2000 In 1989, HP determined that reduced instruction set computer (RISC) architectures were approaching a processing limit at one instruction per cycle. HP researchers investigated a new architecture, later named explicitly parallel instruction computing (EPIC), that allows the processor to execute multiple instructions in each clock cycle. EPIC implements a form of very long [...]

GT.M – Platforms

OpenVMS

GT.M is fully supported on the following platforms (in alphabetic order): * AIX on IBM System p * GNU/Linux on Itanium, x86_64 and IA-32 (x86) architectures *HP-UX on Itanium * Solaris on SPARC *z/OS on IBM System z GT.M is also supported on the following platforms. Although bugs are fixed, releases get new functionality only [...]

Clam AntiVirus – Introduction

OpenVMS

Clam AntiVirus (ClamAV) is a free, cross-platform antivirus software tool-kit capable of detecting many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner. The application was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, Mac OS X, [...]

HP Integrity Virtual Machines – History

OpenVMS

Christophe de Dinechin initiated a skunkworks project to virtualize Itanium, with the help of Jean-Marc Chevrot and of a “virtual team” of experienced HP engineers. A prototype of Integrity Virtual Machines was then developed between 2000 and 2003 by Christophe de Dinechin, Todd Kjos and Jonathan Ross. It was then turned into a full-fledged product [...]

Open Software Foundation – Products

Plan 9 Operating System

OSF’s UNIX reference implementation was known as OSF/1 and was first released in December 1991 and adopted by Digital a month later. As part of the founding of the organization, AIX was provided by IBM and was intended to be a pass-through to the member companies of OSF. However, delays and portability concerns caused the [...]

AlphaStation – Introduction

OpenVMS

AlphaStation was the name given to a series of computer workstations, produced from 1994 onwards by Digital Equipment Corporation, and latterly by Compaq and HP. As the name suggests, the AlphaStations were based on the DEC Alpha 64-bit microprocessor. Supported operating systems for AlphaStations comprise Tru64 UNIX (formerly Digital UNIX), OpenVMS and Windows NT (with [...]

Berkeley Software Distribution – Significant BSD descendants

Unix Operating Systems

:”See also: :Category:BSD and Comparison of BSD operating systems” BSD has been the base of a large number of operating systems. Most notable among these today are perhaps the major open source BSDs: FreeBSD, NetBSD and OpenBSD, which are all derived from 386BSD and 4.4BSD-Lite by various routes. Both NetBSD and FreeBSD started life in [...]
