UNIX and the C Programming Language
“MIT’s early timesharing projects led to the invention of the MULTICS operating system, which ran on General Electric (later Honeywell) mainframe computers. Bell Laboratories contributed to its development until they dropped out of the project in 1969.
Two Bell programmers, Ken Thompson and Dennis Ritchie, independently made a smaller version of MULTICS that ran on a single minicomputer. They called their system UNIX, to represent “one of whatever MULTICS was many of,” and freely distributed it to anyone who asked. An operating system that was not supported by a major computer manufacturer and that was free for the asking was a radical concept in the early 1070s, but was soon adopted by universities and research groups around the world.
The cryptic commands used to control UNIX, such as “is,” “pwd,” “cd,” and “man,” gave it both power and mystery. While these efficient commands still exist in modern variants of the system, the advent of graphical user interfaces (GUIs) made UNIX more accessible. Today, there is a version of UNIX available for almost every commercially available computer, and a strong group of supporters make free versions of UNIX available via the Internet. Programmers developed the C language to simplify the development of UNIX. The C language has since become one of the most widely used languages, particularly for systems programming.”

A flyer for the 'Classic Computing Appreciation Nights' at the Artifactory, run in conjunction with 'Circuit Hacking Mondays'. And, for the benefit of those Perth locals who might stumble across this via a search engine, the text reads:
Classic Computing Appreciation Nights
You are standing in a large warehouse. Around you are several people of impeccable taste, presumably collectors of classic micro- and minicomputers. Behind them are some workbenches with test equipment on them.
>look at people
Most appear to be setting up, repairing, upgrading, modifying or just playing with their classic computers; a few are talking about new projects for their Commodores, Apples and DECs.
>look at benches
You see several soldering stations and CROs, a logic analyser, PAL/SECAM/NTSC and analogue RGB monitors, an EPROM programmer, a large collection of operating system installation kits and a machine capable of reading most of the common floppy disk and tape formats. On one of the benches is a flyer.
>look at flyer
The flyer is of a Commodore 64 and its monitor. The text on the screen says:
When: every second Monday between 7pm—10pm (see website for dates)
Where: the Artifactory — Perth's very own hackerspace in Mount Lawley
Cost: advice and ideas are free; workshop use is $10 waged/$5 unwaged

The Reuben H. Fleet Science Center is a science museum in Balboa Park in San Diego, California. Established in 1973, it was the first science museum to combine interactive science exhibits with a planetarium and an IMAX Dome (OMNIMAX) theater, setting the standard that most major science museums follow today. It is the best-attended museum in the city and is a Top 10 attraction in San Diego.
Throughout the 1960s, the San Diego Hall of Science (now known as the San Diego Space and Science Foundation) was planning a new planetarium for San Diego's Balboa Park, with the possibility of an adjacent science hall. The site on Laurel Street opposite the San Diego Natural History Museum was reserved in 1963. The planetarium would have several innovative features. First of all, the 76-foot-diameter (23 m) dome would be tilted 25 degrees. The audience would be placed in tiered rows facing outward into the tilted dome to give the feeling of being suspended in space. The founders also wanted to develop a large-format film projection system to show movies on the dome. The movies would use the innovative idea of filming through a fisheye lens. This would create a highly distorted image on the film, but with a 180-degree panoramic view. When projected on the dome through another fisheye lens, the distortion would be reversed, and the original panoramic view would be recreated. The audience would have a view that was like being at the original scene. Finally, they wanted to eliminate the large dumbbell-shaped star projector jutting from the center of the room and blocking part of the view. Such a star projector would also interfere with the movies being projected onto the dome.
The San Diego Hall of Science approached Spitz Laboratories to create a new star projector that would not obstruct the view for part of the audience or interfere with the movie projection system. Spitz created a servo-controlled "starball" that became the centerpiece of the system dubbed a "Space Transit Simulator". The spherical star projector and a number of independent planet projectors maintained a low profile while projecting a realistic sky for the astronomy presentations.
These elements, along with a number of slide projectors and lighting systems, were all controlled by a PDP-15 minicomputer. Unlike conventional planetariums, which are limited to showing the night sky as it appears from various points on the surface of the Earth at various dates, the STS could show the sky as it would appear from anywhere within about 100 astronomical units of Earth (about three times the radius of Pluto's orbit). A joystick even allowed the operator to "fly" the theater through space, showing the resulting apparent movement of planets through the sky, though in practice the planetarium presentations were always pre-programmed.
The STS was actually delivered with a flawed mirror inside. Spitz could not make a replacement and install it in time for the debut, so a local amateur telescope maker was called-upon to make a new one. The STS was used for many years but has been replaced by a more modern projector.
For projecting movies onto the dome, the San Diego Hall of Science approached IMAX to adapt their large-screen format. There were technical problems with adapting the IMAX system for use in the center of a dome, but IMAX was willing to address them. The San Diego Hall of Science called the new system OMNIMAX, but IMAX has since renamed the system IMAX Dome. Even though the Reuben H. Fleet Science Center—which coined the original name—now uses the new name, many theaters still call it OMNIMAX.
It was originally planned that presentations could combine images from the planetarium's star and planet projectors with scenes from OMNIMAX films, but this presented many practical problems and was never fully realized.
The planetarium opened in 1973 as the Reuben H. Fleet Space Theater and Science Center showing two features, Voyage to the Outer Planets ( a combined planetarium show and OMNIMAX film produced by Graphic Films) and the OMNIMAX film Garden Isle (by Roger Tilton Films) on a double bill.
In addition to setting a new standard for planetariums, the science center was a pioneer in modern science museums. Following the example set four years earlier by the Exploratorium, all exhibits in the science center were required to have something for visitors to manipulate or otherwise participate in. The combination of a planetarium, IMAX Dome theater and interactive science exhibits is now a common thread with most major science museums. However, by the late 1990s the science center had become small and outdated compared to newer science museums. In 1998 the science center was expanded and modernized to include rides such as the Virtual Zone, a motion-simulator offering virtual rides with a scientific bent. The scientific and interactive exhibits then dwarfed the planetarium/theater, so the name was changed to the current Reuben H. Fleet Science Center.
The facility has been cited as a leading example of energy efficiency and sustainability.
The museum is named for aviation pioneer Reuben H. Fleet, who founded the U.S. Air Mail service. Fleet's San Diego-based company, Consolidated Aircraft, built several of the famous aircraft of World War II, including the B-24 Liberator and PBY Catalina. Fleet and his family made the initial gift which established the Science Center

Galaxy arcade game, 1971
“Galaxy was one of the first coin-operated video games. Using a DEC PDP-11/20 minicomputer, designers Bill Pitts and Hugh Tuck produced a reprogrammed version of the classic SpaceWar! game. The original machines were installed in Stanford University’s Tressider Student Union in September 1971 and quickly became tremendously popular. From 1972 to 1979, Tressider had a second version of the game, featured here, that could include up to four displays. Galaxy was re-installed at Stanford in the William Gates Computer Science Building from 1997 to 2000.”

Redifon Computers made 16-bit minicomputers in the 70's and 80's. They were popular key-to-disk and key-to-tape front ends for the larger machines of the day. This picture shows the system test area where the Basic Control Group and disk drives were brought together for initial testing. The entire system was then moved to Configuration Test where all the terminals and printers were added for full configuration and soak testing was performed.

The AIS center would load changes into this computer from terminals which in turn would batch process them to the AIS system at night. The old AIS center didn't have a Dec-Writer it had an ASR 35 TTY.
Paper tape readers were pretty common on minicomputers back in the '70s and '80s. This one is rather different as it is designed to be attached to an IBM mainframe (I'd never even heard of mainframe-attached paper tape readers or writers before I came across this creature).
CAMA-C replaced the method of recording detailed billing information of customer-dialed calls in CAMA-equipped toll switching machines. CAMA-C utilized a high-speed minicomputer an IBM System/7 to replace the 28 channel paper-tape
perforators and the master timer in existing crossbar tandem and/or 4A installations. Created tapes could be processed at the AMARC center which used DEC PDP 11/70's Mini Computers.
ETS in a 4A Toll Crossbar should not be confused with that in a #5 Crossbar office. The ETS in #5 Crossbar is based on a 3A processor while the ETS in a 4A switch is based on a #1 ESS processor.
