Dave was a Microsoft engineer in the company’s early days. Among other things, he wrote the original Task Manager for Windows, which is still in use today in essentially the same form. He’s far more articulate than I am when describing something I’ve been noticing for years.
Back then, the original IBM PCs typically shipped with just 64K of RAM. Storage was limited to one or two 360K floppy disks. The PC-DOS operating system included a BASIC language interpreter, and all of this — the OS, the interpreter, and whatever application you wanted to run — had to fit inside that single 64K of memory.
Yet with that tiny amount of RAM, you could still boot the machine and run full-featured applications that did much of what we do today: spreadsheets like Lotus 1-2-3, word processors like WordPerfect, and so on.
So what happened? Watch the video to find out.
