19830419

19830419 is a notable date in the history of personal computing, marking the release of the IBM Personal Computer (PC) on April 19, 1983. This event is significant because it introduced the IBM PC to the market, which became a standard for personal computers for many years to come. The IBM PC was designed by a team led by John O. Thompson and was based on the Intel 8088 microprocessor. It featured a 16-bit data bus, 20-bit address bus, and a clock speed of 4.77 MHz. The system came with 16 KB of RAM, which was expandable to 256 KB, and it used a 5.25-inch floppy disk drive for storage. The IBM PC also introduced the concept of an operating system, with MS-DOS (Microsoft Disk Operating System) being the first to be used with the IBM PC. The release of the IBM PC had a profound impact on the personal computing industry, leading to the standardization of hardware and software, and the establishment of the PC as the dominant platform for personal computing.
