Macintosh System 7
System 7 (later named Mac OS 7) is the seventh major release of the classic Mac OS operating system for Mac (computer), Macintosh computers, made by Apple Inc., Apple Computer. It was launched on May 13, 1991, to succeed System 6 with virtual memory, personal file sharing, QuickTime, TrueType fonts, the Force Quit dialog, and an improved user interface. It was codename, code-named "Big Bang" in development and the initial release was named "The System" or "System" like all earlier versions. With version 7.5.1, the name "Mac OS" debuted on the boot screen, and the operating system was officially renamed to Mac OS in 1997 with version 7.6. The Mac OS 7 line was the longest-lasting major version of the Classic Mac OSes due to the Development hell, troubled development of Copland (operating system), Copland, an operating system intended to be the successor to OS 7 before its cancellation and replacement with Mac OS 8. Development By 1988, the Macintosh had been on the market fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Operating Systems
Mac operating systems were developed by Apple Inc. in a succession of two major series. In 1984, Apple debuted the operating system that is now known as the classic Mac OS with its release of the System 1, original Macintosh System Software. The system, rebranded Mac OS in 1997, was pre-installed on every Macintosh until 2002 and offered on Macintosh clones shortly in the 1990s. It was noted for its ease of use, and also criticized for its lack of modern technologies compared to its competitors. The current Mac operating system is macOS, originally named Mac OS X until 2012 and then OS X until 2016. It was developed between 1997 and 2001 after Apple's purchase of NeXT. It brought an entirely new architecture based on NeXTSTEP, a Unix system, that eliminated many of the technical challenges that the classic Mac OS faced, such as problems with memory management. The current macOS is pre-installed with every Mac and receives a major update annually. It is the basis of Apple's curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TrueType
TrueType is an Computer font#Outline fonts, outline font standardization, standard developed by Apple Inc., Apple in the late 1980s as a competitor to Adobe Inc., Adobe's PostScript fonts#Type 1, Type 1 fonts used in PostScript. It has become the most common format for fonts on the classic Mac OS, macOS, and Microsoft Windows operating systems. The primary strength of TrueType was originally that it offered font developers a high degree of control over precisely how their fonts are displayed, right down to particular pixels, at various font sizes. With widely varying Rendering (computer graphics), rendering technologies in use today, pixel-level control is no longer certain in a TrueType font. History ''TrueType'' was known during its development stage, first by the codename "Bass" and later on by the codename "Royal". The system was developed and eventually released as TrueType with the launch of Mac System 7 in May 1991. The initial TrueType outline fonts, four-weight families ...

Blue Meanies (Apple Computer)
The Blue Meanies of Apple Computer was an engineering group primarily responsible for the architecture of System 7 during the early and mid 1990s. The name references the evil characters of Pepperland in the movie '' Yellow Submarine'', and originated with the Pink and Blue split in Apple's operating system planning. Pink was the further-out project that ultimately became Taligent, and Blue designated incremental improvements to the flagship System 7. "Meanies" describes the group's architectural role, which frequently entailed instructing or negating engineers in other groups. Though the Meanies have sometimes been characterized as the "coders of System 7", the OS was by then sufficiently large that major subsystems such as QuickDraw and QuickTime were developed and maintained by specialized groups, and the Meanies primarily focused on orchestrating the components together. The name appeared outside of Apple as an Easter egg starting in System 7.0.1, where the texts "Help! Hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object-oriented
Object-oriented programming (OOP) is a programming paradigm based on the concept of '' objects''. Objects can contain data (called fields, attributes or properties) and have actions they can perform (called procedures or methods and implemented in code). In OOP, computer programs are designed by making them out of objects that interact with one another. Many of the most widely used programming languages (such as C++, Java, and Python) support object-oriented programming to a greater or lesser degree, typically as part of multiple paradigms in combination with others such as imperative programming and declarative programming. Significant object-oriented languages include Ada, ActionScript, C++, Common Lisp, C#, Dart, Eiffel, Fortran 2003, Haxe, Java, JavaScript, Kotlin, Logo, MATLAB, Objective-C, Object Pascal, Perl, PHP, Python, R, Raku, Ruby, Scala, SIMSCRIPT, Simula, Smalltalk, Swift, Vala and Visual Basic.NET. History The idea of "objects" in programm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Index Card
An index card (or record card in British English and system cards in Australian English) consists of card stock (heavy paper) cut to a standard size, used for recording and storing small amounts of discrete data. A collection of such cards either serves as, or aids the creation of, an index (publishing), index for expedited lookup of information (such as a library catalog or a back matter, back-of-the-book index). This system is said to have been invented by Carl Linnaeus, around 1760. Format The most common paper size, size for index card in North America and the UK is , hence the common name 3-by-5 card. Other sizes widely available include , and ISO 216#A series, ISO-size A7 (). Cards are available in blank, ruled and grid styles in a variety of colors. Special divider cards with protruding tabs and a variety of cases and trays to hold the cards are also sold by stationers and office product companies. They are part of standard stationery and office supplies all around t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Mac (computer), Macintosh family of personal computers by Apple Computer, Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the PARC (company), Xerox ...
