The Apple Corporation of America, makers of the famous Apple personal computer, are about to launch a brand new and very interesting new machine. Called the MacIntosh, it is a scaled down version of the recent (and very expensive) Apple Lisa … The Mac has its own 9 inch monochrome monitor and a single Sony 3.5 inch, 500kbyte disc drive. Although the option of a second disc drive is offered, few users are likely to take it. This is because the operating system and applications programmes will be in the form of ROM cartridges, leaving the disc for the user.
