Protected memory was only added to Macintosh computers with the release of the Mac OS X operating system. According to Andy Hertzfeld, the Macintosh used for the introduction demo on January 24, 1984, was a prototype with 512k RAM, even though the first model offered for sale implemented just 128k of non-expandable memory. This prototype was ...
COASt, an acronym for "cache on a stick", is a packaging standard for modules containing SRAM used as an L2 cache in a computer. COASt modules look like somewhat oversized SIMM modules. These modules were somewhat popular in the Apple and PC platforms during early to mid-1990s, but with newer computers cache is built into either the CPU or the ...
The Mac Pro Server includes an unlimited [8] Mac OS X Server license and an Intel Xeon 2.8 GHz quad-core processor, with 8 GB of DDR3 RAM. [114] In mid-2012, the Mac Pro Server was upgraded to an Intel Xeon 3.2 GHz quad-core processor. The Mac Pro Server was discontinued on October 22, 2013, with the introduction of the cylindrical Mac Pro.
The rule of thumb is a 286, 386SX, 68000 or low-end 68020 / 68030 (e.g. Atari Falcon, Mac LC) system (using a 16 bit wide data bus) would require two 30-pin SIMMs for a memory bank. On 386DX , 486 , and full-spec 68020 through 68060 (e.g. Atari TT, Amiga 4000, Mac II) systems (32 bit data bus), either four 30-pin SIMMs or one 72-pin SIMM are ...

The Intel-based MacBook Pro is a discontinued line of Macintosh notebook computers sold by Apple Inc. from 2006 to 2021. It was the higher-end model of the MacBook family, sitting above the low-end plastic MacBook and the ultra-portable MacBook Air, and was sold with 13-inch to 17-inch screens.
For example a stick of RAM that has only 512 megabytes of transfer speed is too slow compared to a stick of RAM that has 16 gigabytes of transfer speeds. [5] Not only does the transfer speeds depend of how fast a RAM can process information, the type of stick of RAM depends as well. For example, there are sticks that can be used DDR3, DDR4 and ...
The introduction of the Desktop and Mini Tower models coincided with Apple starting to sell build-to-order Macs directly from its web site in an online store, [1] [2] which was unusual for the time as Dell was the only major computer manufacturer doing this. Apple's move to build-to-order sales of the Power Macintosh G3 also coincided with the ...
