My first real job was as a computer programmer, on the IBM 360 and 370 mainframe machines, when we used punchcards for input and humongous printouts and 'core dumps' to see where we went wrong. Having *any* kind of a monitor -- even a TV set -- was a treat!
"The May-December marriage of a young company called Microsoft and business powerhouse IBM would change the landscape of offices and homes across the globe.
August 12 is the 25th anniversary of the IBM personal computer launch, a pairing of MS and DOS, Microsoft and the disk operating system.

The IBM stamp of approval on a personal computer changed that mentality for good.
'Almost overnight, with IBM introducing the PC, it became OK to use it for real business applications,' said Tycho Howle, CEO of nuBridges in Atlanta, a provider of business-to-business services.

A floppy disk is a thin, plastic disk that was coated with a magnetic substance used to store data. Earliest disks were 8 inches wide, more efficient disks shrunk to 5 1/4 inches, then 3 1/2 inches. Unlike a CDs or DVDs of today, the disks were floppy, or flexible.
IBM, the 800 pound gorilla of the business world at the time, flooded trade papers and television with promises that this new device would provide "smoother scheduling, better planning, and greater productivity."
