PA-RISC – History

In the late 1980s HP was building four series of computers, all based on CISC CPUs. One line was the IBM PC compatible Intel i286 based Vectra Series started 1986. All others were non-Intel systems. One of them was the HP Series 300 of Motorola 68000-based workstations, another Series 200 line of technical workstations based [...]

Concurrent Versions System – Features

CVS uses a client–server architecture: a server stores the current version(s) of a project and its history, and clients connect to the server in order to “check out” a complete copy of the project, work on this copy and then later “check in” their changes. Typically, the client and server connect over a LAN or [...]

Bill Joy – Early career

After growing up in suburban Detroit, Michigan, Joy received his B.S. in Electrical Engineering from the University of Michigan and his M.S. in EECS from UC Berkeley in 1979. Joy’s PhD advisor was Bob Fabry. As a UC Berkeley graduate student, Joy worked for Fabry’s Computer Systems Research Group CSRG in managing the BSD support [...]

Sun Microsystems – History

The initial design for what became Sun`s first Unix workstation, the Sun-1, was conceived by Andy Bechtolsheim when he was a graduate student at Stanford University in Palo Alto, California. He originally designed the SUN workstation for the Stanford University Network communications project as a personal CAD workstation. It was designed as a 3M computer: [...]

Ring (computer security) – Implementations

Hardware supported rings were among the most revolutionary concepts introduced by the Multics operating system, a highly secure predecessor of today’s UNIX family of operating systems. However, most general-purpose systems use only two rings, even if the hardware they run on provides more CPU modes than that. For example, Windows XP and below only uses [...]

ProvideX – Introduction

ProvideX is a computer language and development environment derived from Business Basic (a business oriented derivative of BASIC) in the mid-1980s. ProvideX is available on several operating systems (Unix/Linux/Windows/Mac OS X) and includes not only the programming language but also file system, presentation layer interface, and other components. The language is primarily designed for use [...]

Netpbm – Introduction

Netpbm is an open source package of graphics programs and a programming library, used mainly in the Unix world. It is a highly portable package, working under many Unix platforms, Windows, Mac OS X, VMS, Amiga OS and others and is included in all major open source Unix-like operating system distributions. Adapted from the Wikipedia [...]

History of the graphical user interface – The 80s: Early commercial developments

Apple Lisa and Macintosh (and later, the Apple IIgs) Beginning in 1979, started by Steve Jobs and led by Jef Raskin, the Lisa and Macintosh teams at Apple Computer (which included former members of the Xerox PARC group) continued to develop such ideas. The Macintosh, released in 1984, was the first commercially successful product to [...]

AMD Lance Am7990 – Uses

* Amiga 2065 the first Ethernet controller for Amiga computer family. Uses the Zorro-II bus interface and equipped with the NMOS Am7990 chip. * MicroVAX Q-Bus Ethernet controllers (like the DELQA). * DECstation 2100/3100 MIPS architecture motherboard Ethernet. * DEC 3000 AXP 64-bit Alpha AXP architecture motherboard. * Sun Microsystems Sun Hydra 3/80, SPARCstation 1, [...]

Xinet – History

A key part of Xinet history has been the company’s expertise in Unix operating systems. AT&T first distributed their Unix source-code to university researchers at Carnegie Melon and U.C. Berkeley. U.C. Berkeley researchers popularized their own version of Unix, which became known as “Berkeley Unix.” In 1979, when AT&T announced its intention to commercialize Unix, [...]

RISC OS – Demise of Acorn Computers Ltd

Acorn officially halted work in all areas except set-top boxes in late 1998 and the company was renamed Element 14 (the 14th element of the periodic table being silicon) with a new goal to become purely a Silicon design business (like the previous very successful spin off of ARM from Acorn in 1990). RISC OS [...]

Ioctl – Uses

Hardware device configuration The most common use of ioctls is to control hardware devices. For example, on Win32 systems, ioctl calls are used to communicate with USB devices, or to discover drive geometry information for attached storage devices. Ioctls are used on Unix systems to configure the network interfaces. For example, on BSD Unix systems [...]

Moria (video game) – History

The original version was written at the University of Oklahoma by Robert Alan Koeneke and Jimmey Wayne Todd, after they became hooked on ”Rogue” but could not run it on the VAX-11/780 minicomputer to which they had access. Version 1.0 was written in VMS Pascal and completed in the summer of 1983. From around 1985 [...]

SCO v. IBM – Introduction

”SCO v. IBM” is a civil lawsuit in the United States District Court of Utah. The SCO Group asserted that there are legal uncertainties regarding the use of the Linux operating system due to alleged violations of IBM’s Unix licenses in the development of Linux code at IBM. Adapted from the Wikipedia article SCO v. [...]
