MONECS
MONECS ( Monash University Educational Computing System) was a computer operating system with BASIC, COBOL, FORTRAN, Pascal interpreters, plus machine language facility. Specifically designed for computer science education in Australian secondary schools and at the university undergraduate level. Alternative designations were DEAMON (Digital Equipment Australia - Monash University) or SCUBA (local designation at Melbourne University) systems. Overview For teaching computer science students in Australian schools Monash University created subsets of the FORTRAN language, an elementary version called MINITRAN then an enhanced version called MIDITRAN. MIDITRAN versions were available for a number of different mainframe systems, i.e. Burroughs B5000/B5500 series, CDC 3000, IBM 360 and ICL 1900. Student's programs were submitted on IBM Port-a-Punch cards that can be programmed with an IBM board and stylus or even a bent paper clip. Standard 80-column punch cards were an option for ...

PDP-11
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. The PDP-11 included a number of innovative features in its instruction set and additional general-purpose registers that made it much easier to program than earlier models in the PDP series. Further, the innovative Unibus system allowed external devices to be easily interfaced to the system using direct memory access, opening the system to a wide variety of peripherals. The PDP-11 replaced the PDP-8 in many real-time computing applications, although both product lines lived in parallel for more than 10 years. The ease of programming of the PDP-11 made it very popular for general-purpose computing uses also. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 360
The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover both commercial and scientific applications and to cover a complete range of applications from small to large. The design distinguished between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices. All but the only partially compatible Model 44 and the most expensive systems use microcode to implement the instruction set, which features 8-bit byte addressing and binary, decimal, and hexadecimal floating-point calculations. The System/360 family introduced IBM's Solid Logic Technology (SLT), which packed more transistors onto a circuit card, allowing more powerful but smaller computers to be built. The slowest System/360 model announced in 1964, the Model 30, could perform up to 34,500 instructions per second, with memory ...

Lineprinter
A line printer prints one entire line of text before advancing to another line. Most early line printers were impact printers. Line printers are mostly associated with unit record equipment and the early days of digital computing, but the technology is still in use. Print speeds of 600 lines per minute (approximately 10 pages per minute) were achieved in the 1950s, later increasing to as much as 1200 lpm. Line printers print a complete line at a time and have speeds in the range of 150 to 2500 lines per minute. The types of line printers are drum printers, band-printers, and chain printers. Other non-impact technologies have also been used, as thermal line printers were popular in the 1970s and 1980s, and some inkjet and laser printers produce output a line or a page at a time. Designs Many impact printers, such as the daisywheel printer and dot matrix printer, used a print head that printed a character then moved on until an entire line was printed. Line printers we ...

Documation Inc
Documation was an American Stock Exchange-listed computer hardware manufacturer founded in 1969 in Melbourne, Florida that went public in 1976. They made (punched card) card readers used in some American elections 3 decades later. They also produced Impact Line printers. In late 1980, Storage Technology Corporation (STC) acquired Documation, which was subsequently spun off, and those companies which subdivided from it, most of which use Documation-like names, no longer manufacture computer peripherals. Documation was described as "a financially troubled printer manufacturer." IMPACT Line printers Documation's ''IMPACT 3000'', named for its 3,000 lines per minute rating, was followed a year later by the 3,800 LPM ''IMPACT 3800''. A 5,000 lines per minute printer was introduced in 1986, by which time the company was operating under the name StorageTek Printer Corp. Like earlier impact printer models, it is manufactured in Florida. At the time of the Series 5000's introducti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally esta ...

Mark Sense
Electrographic is a term used for punched-card and page-scanning technology that allowed cards or pages marked with a pencil to be processed or converted into punched cards. The primary developer of electrographic systems was IBM, who used mark sense as a trade name for both the forms and processing system. The term has since come to be used generically for any technology allowing marks made using ordinary writing implements to be processed, encompassing both optical mark recognition and electrographic technology. The term "mark sense" is not generally used when referring to technology that distinguishes the shape of the mark; the general term optical character recognition is generally used when mark shapes are distinguished. Because the term mark-sense was originally a trade name, the Federal Government generally used the term electrographic. In the 1940s, 50s, and 60s, mark sense technology was widely used for applications like processing meter readings recordings on turnar ...

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.
