IBM Personal Computer (IBM-PC)

 
  • The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It is IBM model number 5150, and was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida.
  • The IBM Personal Computer ("PC") was not as powerful as many of the other personal computers it was competing against at the time of its release. The simplest configuration has only 16K on-board RAM and uses an audio cassette to load and save data - the floppy drive was optional, and a hard drive was not suported.
  • A basic system for home use attaches to an audio tape cassette player and a television set (that means no floppy drives or video monitor) sold for approximately $1,565. PC-DOS, the operating system, was not available on cassette, so this basic system is only capable of running the Microsoft BASIC programming language, which is built-in and included with every PC.
  • A more typical system for home or school with a memory of 64K bytes, a single diskette drive and its own display, was priced around $3,000.
  • An expanded system for business with color graphics, two diskette drives, and a printer cost about $4,500.
