Macintosh 1. 28. K Wikipedia. The Macintosh 1. 28. K, originally released as the Apple Macintosh, is the original Apple. Macintoshpersonal computer. Its beige case consisted of a 9 in 2. CRT monitor and came with a keyboard and mouse. A handle built into the top of the case made it easier for the computer to be lifted and carried. It had an initial selling price of 2,4.

The iPod is a line of portable media players and multipurpose pocket computers designed and marketed by Apple Inc. The first version was released on October 23, 2001. The Macintosh was introduced by the now famous 3. Ridley Scott, 1. CBS during the third quarter of Super Bowl XVIII on January 2. Installing Nextgen Gallery. Sales of the Macintosh were strong from its initial release on January 2. May 3, 1. 98. 4. 7 Upon the release of its successor, the Macintosh 5. K, it was rebranded as the Macintosh 1. K. Processor and memoryeditThe centerpiece of the machine was a Motorola 6. MHz, connected to 1. KB RAM shared by the processor and the display controller. The boot procedure and some operating system routines were contained in an additional 6. Inspiration 9 Software Serial Finder' title='Inspiration 9 Software Serial Finder' />KBROM chip. Apple did not offer RAM upgrades. Unlike the Apple II, no source code listings of the Macintosh system ROMs were offered. The RAM in the Macintosh consisted of sixteen 4. DRAMs. The 6. 80. DRAM every four CPU cycles during display of the frame buffer, while the 6. DRAM during vertical and horizontal blanking intervals. Such an arrangement reduced the overall performance of the CPU as much as 3. CPUs access to RAM. This made the machine run more slowly than several of its competitors, despite the nominally high clock rate. Back case of an unaltered original Macintosh sold JanuaryNovember 1. Those made after November 1. Macintosh 1. 28. K on the back of the case. PeripheralseditThe built in display was a one bit black and white, 9 in 2. CRT with a fixed resolution of 5. PPI. 8 Expansion and networking were achieved using two non standard RS 4. How To Install Windows Messaging Subsystem. DE 9 serial ports named printer and modem they did not support hardware handshaking. An external floppy disk drive could be added using a proprietary connector 1. D sub. The keyboard and mouse used simple proprietary protocols, allowing some third party upgrades. The original keyboard had no arrow keys, numeric keypad or function keys. This was an intentional decision by Apple, as these keys were common on older platforms and it was thought that the addition of these keys would encourage software developers to simply port their existing applications to the Mac, rather than design new ones around the GUI paradigm. Later, Apple would make a numeric keypad available for the Macintosh 1. K. The keyboard sold with the newer Macintosh Plus model would include the numeric keypad and arrow keys, but still no function keys. As with the Apple Lisa before it, the mouse had a single button. Standard headphones could also be connected to a monaural jack. Apple also offered their 3. Apple II line. Initially, the only printer available was the Apple Image. Writer, a dot matrix printer which was designed to produce 1. WYSIWYG output from the Macs 7. Eventually, the Laser. Writer and other printers were capable of being connected using Apple. Talk, Apples built in networking system. StorageeditThe Macintosh contained a single 4. KB, single sided 3. The Mac OS was disk based from the beginning, as RAM had to be conserved, but this Startup Disk could still be temporarily ejected. Ejecting the root filesystem remained an unusual feature of the classic Mac OS until System 7. One floppy disk was sufficient to store the System Software, an application and the data files created with the application. Indeed, the 4. 00 KB drive capacity was larger than the PC XTs 3. KB 5. 2. 5 inch drive. However, more sophisticated work environments of the time required separate disks for documents and the system installation. Due to the memory constraints 1. KB of the original Macintosh, and the fact that the floppies could hold 4. KB, users frequently had to swap disks in and out of the floppy drive. For this reason, external floppy drives were frequently used. The Macintosh External Disk Drive mechanically identical to the internal one, piggybacking on the same controller was a popular add on at US 4. Third party hard drives were considerably more expensive and usually connected to the slower serial port as specified by Apple, though a few manufacturers chose to use the faster non standard floppy port. The 1. 28. K can only use the original Macintosh File System for storage. CoolingeditThe unit did not include a fan, relying instead on convection cooling, which made it quiet while in operation. Steve Jobs insisted that the Macintosh ship without a fan, which persisted until the introduction of the Macintosh SE in 1. This was allegedly a source of many common, costly component failures in the first four Macintosh models. This was enough of a problem to prompt the introduction of a third party, external cooling fan. This fan unit fitted inside the Macintoshs carrying handle slot and produced a forced draft through the computers existing ventilation holes. SoftwareeditThe Macintosh shipped with the very first System and Finder application, known to the public as System 1. System 0. 9. 7 and Finder 1. The original Macintosh saw three upgrades to both before it was discontinued. Apple recommends System 2. Finder 4. 2, with System 3. Finder 5. 3 as the maximum. System 4. 0 officially dropped support for the Macintosh 1. K because it was distributed on 8. KB floppy disks, which could not be used by the 1. K. The applications Mac. Paint and Mac. Write were bundled with the Mac. Other programs available included Mac. Project, Mac. Terminal and Microsoft Word. Programming languages available at the time included Mac. BASIC, Mac. Pascal1. Macintosh 6. 80. 00 Development System. The Macintosh also came with a manual and a unique guided tour cassette tape which worked together with the guided tour diskette as a tutorial for both the Macintosh itself and the bundled applications, since most new Macintosh users had never used a mouse before, much less manipulated a graphical user interface. Back case label of a Macintosh made after November 1. The computer was released in January 1. Apple Macintosh. Following the release of the Macintosh 5. K in September, which expanded the memory from 1. KB to 5. 12 KB, the original Macintosh was re branded Macintosh 1. K and nicknamed the thin Mac. The new 5. K model was nicknamed the fat Mac. While functionally the same, as closed systems, the Macintosh and Macintosh 1. K were technically two different computers, with the re badged 1. K containing a completely redesigned logic board to easily accommodate both 1. KB and 5. 12 KB RAM configurations during manufacturing. Rainmeter Skin Installer Download here. Though the RAM was still permanently soldered to the logic board, the new design allowed for easier though unsanctioned third party upgrades to 5. KB. In addition, most of the newer models contained the 1. B of the ROM to accommodate changes in the 4. KB floppy disk drive. System software contains support for an unreleased Macintosh 2. K. 1. 4The increased RAM of the 5. K was vitally important for the Macintosh as it finally allowed for more powerful software applications, such as the then popular program Microsoft Multiplan. However, Apple continued to market the 1. K for over a year as an entry level computer, the mid level 5. K and high end Lisa and claiming that it could be easily expanded should the user ever need more RAM. ExpansioneditJobs stated that because customization really is mostly software now.
