Trapeze (spreadsheet Program)
Trapeze is a discontinued spreadsheet program for Macintosh systems running classic Mac OS. It introduced the concept of using named ranges for most operations instead of cell addresses, allowing formulas to be freed of the location of the data on the page. This, in turn, made updating the sheets by moving data around a safe operation, whereas in contemporary programs like Microsoft Excel and Lotus 1-2-3 this often led to broken formulas. The system did not rely on the sheet as the basis for storage, and allowed multiple tables, charts, graphics and text, which they referred to as "blocks", to be positioned freely. Introduced in January 1987 at MacWorld San Francisco, sales were not strong and the company formed to introduce the product was insolvent by the fall. The company was purchased by a minicomputer software vendor as part of an effort to break into the microcomputer market, but they decided to exit the business and sold it off again to a new company, DeltaPoint, in 1989.

20/20 (spreadsheet Software)
20/20 is a discontinued spreadsheet program developed by Access Technology Inc., of South Natick, Massachusetts, and later sold by CA Technologies. For a while, it was the dominant spreadsheet on VAX minicomputers. It was a direct competitor to Lotus 1-2-3, and was available for more operating systems than 1-2-3. 20/20's performance specifications were similar to those of 1-2-3. The software was originally titled "Supercomp-20". It was renamed 20/20, and was available for AT&T Unix The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. M ..., DEC VAX, Prime Computers, the IBM RS/6000, Data General and IBM-compatible PCs. It was the first spreadsheet with integrated database and graphics support available for Unix. In 1989, a version was released with real-time data updating. 20/20 also had mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh XL
Macintosh XL is a modified version of the Apple Lisa personal computer made by Apple Computer In the Macintosh XL configuration, the computer shipped with MacWorks XL, a Lisa program that allowed 64 K Macintosh ROM emulation. An identical machine was previously sold as Lisa 2/10 with the Lisa OS only. Hardware Macintosh XL has a 400K 3.5" floppy drive and an internal 10 MB proprietary "Widget" hard drive with provision for an optional 5 or 10 MB external ProFile hard drive with the addition of a parallel interface card. The machine uses a Motorola 68000 CPU, clocked at 5 MHz together with 512 KB RAM. Macintosh XL was discontinued in April 1985. Upgrades Because of its roots as a Lisa — unlike all other Macintosh computers — the stock Macintosh XL used rectangular pixels. The resolution of Macintosh XL's 12-inch (30.5 cm) display was 720×364 pixels. Square pixels were available through the Macintosh XL Screen Kit upgrade that changed the resolution ...

MindWrite
MindWrite is word processor software for early Apple Macintosh, Macintosh computers running classic Mac OS. It was released in 1986 by MindWork Software, making it among the earliest 3rd party word processors on the platform. It was later distributed by Access Technologies, who then transferred their Mac software to a spinoff, DeltaPoint. Sales continued with DeltaPoint at least into the early 1990s. The key feature of MindWrite was its integrated outliner, a system that allowed documents to be organized in a hierarchy and then re-arranged with drag-and-drop operations. After the release of the pioneering MORE (application), ThinkTank, such systems were considered to be a new way to organize knowledge and perform workflows. MindWrite was the first program to cleanly integrate an outliner with a word processor. and this generated considerable press for the product. The system was otherwise fairly simple in terms of style and layout options and initially lacked a spell checker, issue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MacUser (US Edition)
''MacUser'' was a monthly computer magazine published by Ziff Davis in the United States, while the UK edition was published by Dennis Publishing. History and profile ''MacUser'' started publication in late 1985 as a four-color monthly and contained general interest Mac articles. In 1986 the magazine was acquired by Ziff Davis. It had reviews and regular columns for novice and experienced users with a more humorous view of the Macintosh world than other publications of the time. Games were reviewed and well as business and productivity software. A unique feature, not available in other publications, was the inclusion of about 250 capsule reviews in each edition. The initial cover price was $3.50 with an annual subscription of $23 per year or $42 for two-years. In 1997, the publication was absorbed into ''Macworld'' as ''Macworld, incorporating MacUser'' (a name reflected subtly on the magazine's Table of Contents page) reflecting a consolidation of the Ziff Davis-owned ''MacUser ...

Motorola 68881
The Motorola 68881 and Motorola 68882 are floating-point units (FPUs) used in some computer systems in conjunction with Motorola's 32-bit 68020 or 68030 microprocessors. These coprocessors are external chips, designed before floating point math became standard on CPUs. The Motorola 68881 was introduced in 1984. The 68882 is a higher performance version produced later. Overview The 68020 and 68030 CPUs were designed with the separate 68881 chip in mind. Their instruction sets reserved the "F-line" instructions – that is, all opcodes beginning with the hexadecimal digit "F" could either be forwarded to an external coprocessor or be used as "traps" which would throw an exception, handing control to the computer's operating system. If an FPU is not present in the system, the OS would then either call an FPU emulator to execute the instruction's equivalent using 68020 integer-based software code, return an error to the program, terminate the program, or crash and require a rebo ...

Menu (computing)
In user interface design, a menu is a list of options or commands presented to the user of a computer or embedded system. A menu may either be a system's entire user interface, or only part of a more complex one. Navigation A user chooses an option from a menu by using an input device. Some input methods require linear navigation: the user must move a cursor or otherwise pass from one menu item to another until reaching the selection. On a computer terminal, a reverse video bar may serve as the cursor. Touch user interfaces and menus that accept codes to select menu options without navigation are two examples of non-linear interfaces. Some of the input devices used in menu interfaces are touchscreens, keyboards, mice, remote controls, and microphones. In a voice-activated system, such as interactive voice response, a microphone sends a recording of the user's voice to a speech recognition system, which translates it to a command. Types of menus A computer using a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macworld
''Macworld'' is a website dedicated to products and software of Apple Inc., published by Foundry, a subsidiary of IDG Inc. It started life as a print magazine in 1984 and had the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, '' MacLife'' (formerly ''MacAddict''). ''Macworld'' was founded by David Bunnell and Cheryl Woodard (publishers) and Andrew Fluegelman (editor). It was the oldest Macintosh magazine still in publication, until September 10, 2014, when IDG, its parent company, announced it was discontinuing the print edition and laid off most of the staff, while continuing an online version.

Trapeze (band)
Trapeze were an English rock band from Cannock, Staffordshire. Formed in 1969, the band originally featured former The Montanas members John Jones (trumpet, vocals) and Terry Rowley (keyboards), and former Finders Keepers members Glenn Hughes (bass, vocals, piano), Mel Galley (guitar, vocals) and Dave Holland (drums). Jones and Rowley left the band following the release of their self-titled debut album in 1970, with the lineup of Hughes, Galley and Holland continuing as a trio. After the release of ''Medusa'' later in 1970 and '' You Are the Music... We're Just the Band'' in 1972, Hughes left Trapeze in 1973 to join Deep Purple. Galley and Holland resurfaced with Trapeze a year later, adding second guitarist Rob Kendrick and bassist Pete Wright to the band. '' Hot Wire'' was released in late 1974 and a second self-titled album followed in 1975, after which the classic trio briefly reunited for a tour in 1976 when Hughes returned following Deep Purple's breakup.

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows User (computing), users to Human–computer interaction, interact with electronic devices through graphical icon (computing), icons and audio indicator such as primary notation, instead of text-based user interface, text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs (command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through Direct manipulation interface, direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and Distributed control system, industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution User ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
