The Apple Macintosh was a personal computer produced in 1984 based on the Motorola 68000 32-bit processor running at 7.83 Mhz as an alternative to the IBM personal computer. The Apple Macintosh was revolutionary in introducing the 'Lisa' concept of a computer simulating an office environment on the screen with a 'mouse' used to run a cursor around to sort through pages and files. The Apple
Macintosh had a 9-inch 512 x 342 pixel resolution monochrome monitor and a 3.5 inch 400 kb capacity floppy disk drive and an internal 800 kb disk drive and 512 kb of RAM.
