It shared a revised logic board with the rebadged Macintosh 128K (previously just called the Macintosh), which streamlined manufacturing. The resolution of the display was the same at 512 × 342. Apple sold a memory upgrade for the Macintosh 128K for $995 initially, and reduced the price when 256 Kb DRAM prices fell months later. [4]
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 ...
Mac gaming refers to the use of video games on Macintosh personal computers. In the 1990s, Apple computers did not attract the same level of video game development as Microsoft Windows computers due to the high popularity of Windows and, for 3D gaming, Microsoft's DirectX technology.
For this reason, 512Ke users' only hard disk option is the slower, floppy-port-based Hard Disk 20, or similar products for the serial port, even though the 512Ke ROMs contain the "SCSI Manager" software that enables the use of faster SCSI hard disks (because the ROMs are the same as the ones used in the Mac Plus, which does have a SCSI port ...
In September 1984, after months of complaints over the Mac's inadequate RAM, Apple released an official 512 KB machine (The Macintosh 512K). Although this had always been planned from the beginning, Steve Jobs maintained if the user desired more RAM than the Mac 128 provided, he should simply pay extra money for a Mac 512 rather than upgrade ...
Storage started at 128 GB SSD, with options for 256 GB and 512 GB. The Haswell considerably improved battery life from the previous models, and the models are capable of 9 hours on the 11-inch model and 12 hours on the 13-inch model; a team of reviewers exceeded expected battery life ratings during their test.

Memory areas of the IBM PC family. In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes of the memory on IBM PC or compatible systems. It is the read-write memory directly addressable by the processor for use by the operating system and application programs.
