A somewhat-convoluted connection for a computer tie: 1984 should probably be known as the foundational year for personal computers, because both the first Macintosh and the IBM AT were released in January. My tie honors the release of "MS-DOS 3.0" on this date that year, which was the first operating system (for IBM) to support 5.25" floppy disks with 1.2 MB storage -- to be used in AT-class computers (as shown on my tie). Microsoft released "Windows 1.0" in 1985, but Microsoft and IBM continued to develop MS-DOS through version 6.22. And MS-DOS remained inside the Windows operating systems up through Windows 2000/ME.
