Description
 			Originally released as simply the Macintosh, the Macintosh 128K  was the first of the Macintosh line.  The single beige case contained a  nine-inch monochrome monitor and it came with a 3.5” floppy drive, a  keyboard and mouse.  The processor was a Motorola 68000 chip that was  capable of running at speeds of up to 8Mhz.  It had 128K of RAM and 64K  of ROM.   
  A single 400K single-sided floppy disk was, at that time, large enough  to store system files, an application and the data files associated with  it.  However, most users chose to write-protect their Systems and  Applications disks, with the result being that they had to switch disks  in and out frequently.  
  The nine-inch monitor had a crisp, clear display with a resolution of  512x342.  This was the computer that established the desktop publishing  standard of 72 pixels per inch (PPI). 
 
 			
History
 			The Macintosh 128K was the first GUI-based computer that was  affordable to the home user with a price of $2,495.  Apple marketed it  extensively at its release in 1984, including an ad during the NFL  Superbowl.  Initial sales were slow and Apple did not license the  operating system or the hardware, so there were no third party options  available.   
  The Macintosh 128K was shipped with a few programs: MacWrite and  MacPaint.  The user interface would become the face of the Macintosh  line and the inspiration for IBM’s Windows and other GUIs. 
  In 1985, sales were increased with the release of Aldus Pagemaker and  the LaserWriter printer, which, for the first time, made home desktop  publishing possible.  
  
Because it was sold without a cooling fan at Steve Jobs’ insistence, the  computer ran very quietly but was prone to overheating.  Because of  this and the design of the floppy driver, the Macintosh 128 was  nicknamed the “beige toaster.”
