Hard Disk 20
The Macintosh Hard Disk 20 was the first hard drive developed by Apple Computer specifically for use with the Macintosh 512K. Introduced on September 17, 1985, it was part of Apple's long-awaited solution toward completing the Macintosh Office (a suite of integrated business hardware & software) announced in January 1985. It would be over a year more before Apple would release the file server software AppleShare that would link all of the hardware together. By that time the SCSI interface introduced on the Macintosh Plus in January 1986, would accommodate far faster and more efficient hard drives, rendering the Hard Disk 20 virtually obsolete. Features The Hard Disk 20 (or ''HD20'', as it was known colloquially) contains a 20 MB 3.5" Rodime hard disk which provides over 50 times the data storage of the stock 400 kB disk drive. At the time when the average file size was around 10-20 kB and due to the vast number of those files the HD20 can contain, Apple's original Macintosh Fil ...

Hierarchical File System
Hierarchical File System (HFS) is a proprietary file system developed by Apple Inc. for use in computer systems running Mac OS. Originally designed for use on floppy and hard disks, it can also be found on read-only media such as CD-ROMs. HFS is also referred to as Mac OS Standard (or HFS Standard), while its successor, HFS Plus, is also called Mac OS Extended (or HFS Extended). With the introduction of Mac OS X 10.6, Apple dropped support for formatting or writing HFS disks and images, which remain supported as read-only volumes. Starting with macOS 10.15, HFS disks can no longer be read. History Apple introduced HFS in September 1985, specifically to support Apple's first hard disk drive for the Macintosh, replacing the Macintosh File System (MFS), the original file system which had been introduced over a year and a half earlier with the first Macintosh computer. HFS drew heavily upon Apple's first hierarchical operating system (SOS) for the failed Apple III, which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macintosh II
The Macintosh II is a personal computer designed, manufactured, and sold by Apple Computer from March 1987 to January 1990. Based on the Motorola 68020 32-bit CPU, it is the first Macintosh supporting color graphics. When introduced, a basic system with monitor and 20 MB hard drive cost . With a 13-inch color monitor and 8-bit display card the price was around . This placed it in competition with workstations from Silicon Graphics, Sun Microsystems, and Hewlett-Packard. The Macintosh II was the first computer in the Macintosh line without a built-in display; a monitor rested on top of the case like the IBM Personal Computer and Amiga 1000. It was designed by hardware engineers Michael Dhuey (computer) and Brian Berkeley (monitor) and industrial designer Hartmut Esslinger (case). Eighteen months after its introduction, the Macintosh II was updated with a more powerful CPU and sold as the Macintosh IIx. In early 1989, the more compact Macintosh IIcx was introduced at ...

System 6
System 6 (or System Software 6) is a graphical user interface-based operating system for Macintosh computers, made by Apple Computer It was released in 1988, and is part of the classic Mac OS series. It is a monolithic operating system, with cooperative multitasking based on an improved MultiFinder. The boxed version cost , and it was included with all new Macintosh computers until 1991, when it was succeeded by System 7. Overview MacroMaker The MacroMaker utility was introduced in System 6. It records mouse and keyboard input as macros, and has a unique user interface intended to look and act like a tape recorder. MacroMaker was criticized for its lack of features when compared to Microsoft's AutoMac III, which was already available commercially. As MacroMaker records only the locations of mouse-clicks inside windows and not what is being clicked on or exactly when, it can not be used to automate actions in more sophisticated programs. The pre-recorded clicks miss button ... [...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 ...

Hard Disk 20SC
The Apple Hard Disk 20SC is Apple's first SCSI based hard drive for the Apple II family as well as the Macintosh and other third party computers using an industry standard SCSI interface. History Released in September 1986 along with the Apple IIGS (which required an optional SCSI interface card to use it), it debuted over 9 months after the introduction of the Macintosh Plus, the first to include Apple's SCSI interface. It was a welcome addition, delivering considerably faster data transfer rates (up to 1.25 megabytes per second) than its predecessors, the Hard Disk 20 (62.5 Kilobytes per second) and '' ProFile''. Hardware The 20SC originally contained a half height 5.25" Seagate ST-225N 20MB SCSI hard drive, but was later manufactured with a full-height 3.5" MiniScribe 8425SA 20MB SCSI hard drive. The latter drive was the same size as the drive inside the Macintosh Hard Disk 20, but 10 to 15 MB over what had previously been offered by Apple for the II family. The same drive ...

Serial Ports
In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, terminals, various peripherals, and directly between computers. While interfaces such as Ethernet, FireWire, and USB also send data as a serial stream, the term ''serial port'' usually denotes hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422. Modern consumer personal computers (PCs) have largely replaced serial ports with higher-speed standards, primarily USB. However, serial ports are still frequently used in applications demanding simple, low-speed interfaces, such as industrial automation systems, scientific instruments, point of sale systems and some industrial and consumer prod ...

Read-only Memory
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications (like video games) for programmable devices can be distributed as plug-in cartridges containing ROM. Strictly speaking, ''read-only memory'' refers to memory that is hard-wired, such as diode matrix or a mask ROM integrated circuit (IC), which cannot be electronically changed after manufacture. Although discrete circuits can be altered in principle, through the addition of bodge wires and/or the removal or replacement of components, ICs cannot. Correction of errors, or updates to the software, require new devices to be manufactured and to replace the installed device. Floating-gate ROM semiconductor memory in the form of e ...

Macintosh 512Ke
The Macintosh 512K ''enhanced'' (512Ke) was introduced in April 1986 as a cheaper alternative to the top-of-the-line Macintosh Plus, which had debuted three months previously. It is the same as the Macintosh 512K but with the 800K disk drive and 128K of ROM used in the Macintosh Plus. Like its predecessors, it has little room for expansion. Some companies did create memory upgrades that brought the machine up to 2 MB or more. Model differences Originally, the case was identical to its predecessor, except for the model number listed on the rear bucket's agency approval label. It used the same beige-like color as well. But like the Macintosh Plus, in 1987 the 512Ke adopted the standard Apple "Platinum" color, as well as the same case-front design as the Plus (without the name), though keeping its original rear bucket. Later in its lifespan, the 512Ke was discounted and offered to the educational market, badged as the ''Macintosh ED'' (M0001D & later M0001ED). The 512Ke shipped ...

Macintosh 128K
The Apple Macintosh—later rebranded as the Macintosh 128K—is the original Apple Macintosh personal computer. It played a pivotal role in establishing desktop publishing as a general office function. The motherboard, a CRT monitor, and a floppy drive were housed in a beige case with integrated carrying handle; it came with a keyboard and single-button mouse. It sold for . The Macintosh was introduced by a television commercial entitled " 1984" shown during Super Bowl XVIII on January 22, 1984 and directed by Ridley Scott. Sales of the Macintosh were strong from its initial release on January 24, 1984, and reached 70,000 units on May 3, 1984. Upon the release of its successor, the Macintosh 512K, it was rebranded as the Macintosh 128K. The computer's model number was M0001. Development 1978–1984: Development In 1978 Apple began to organize the Apple Lisa project, aiming to build a next-generation machine similar to an advanced Apple II or the yet-to-be-introduced ...

Finder (software)
The Finder is the default file manager and graphical user interface shell used on all Macintosh operating systems. Described in its "About" window as "The Macintosh Desktop Experience", it is responsible for the launching of other applications, and for the overall user management of files, disks, and network volumes. It was introduced with the first Macintosh computer, and also exists as part of GS/OS on the Apple IIGS. It was rewritten completely with the release of Mac OS X in 2001. In a tradition dating back to the Classic Mac OS of the 1980s and 1990s, the Finder icon is the smiling screen of a computer, known as the Happy Mac logo. Features The Finder uses a view of the file system that is rendered using a desktop metaphor; that is, the files and folders are represented as appropriate icons. It uses a similar interface to Apple's Safari browser, where the user can click on a folder to move to it and move between locations using "back" and "forward" arrow buttons. Li ...
