context_page_description: The Macintosh 128K, originally released as the Apple Macintosh, is the original Apple Macintosh personal computer. Its beige case consisted of a 9 in 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 $2,495. The Macintosh was introduced by the now-famous $370,000 television commercial directed by Ridley Scott, "1984", that aired on CBS during the third quarter of Super Bowl XVIII on January 22, 1984. 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 is Model M0001.
context_section_description: The Macintosh contained a single 400 KB, single-sided ​3 ¹⁄₂-inch floppy disk drive, dedicating no space to other internal mechanical storage. 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 400 KB drive capacity was larger than the PC XT's 360 KB 5.25-inch drive. However, more sophisticated work environments of the time required separate disks for documents and the system installation. Due to the memory constraints (128 KB) of the original Macintosh, and the fact that the floppies could hold 400 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 $495. 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 nonstandard floppy port. The 128K can only use the original Macintosh File System for storage.
