The IBM PC was released in August of 1981 and ran on a 4.77-MHz Intel 8088 microprocessor. It came equipped with a cassette port and 16 Kbytes of memory, expandable to whopping 256 Kbytes. It had one or two single-sided 160-Kbyte floppy disk drives, but they were optional-over the $1,565 base price. A monochrome or color monitor was also optional. A typical system with a memory of 64 Kbytes, 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. DOS 1.0 added $40 to the price.
