All Macintosh Models | All 1984 Models | Dynamically Compare This Mac to Others

Apple Macintosh 128k The Apple Macintosh (128k) features an 8 MHz 68000 processor, 128k of RAM, and a 400k disk drive in a beige all-in-one case with a 9" monochrome display.

The Macintosh (128k) was the first relatively inexpensive computer to use a graphical user interface, 3.5" disks, a consistent look-and-feel among applications, and true WYSIWYG printing, all of which are taken for granted today. This computer started a different way of thinking, allowing the user to concentrate on working rather than struggling to get the computer to work.
