Seriously? You think Microsoft invented the mouse and keyboard? The first machine to have a mouse was the Xerox 8010 in 1981, it was integral to the Mac in 1984. Windows didn't turn up in a form that could use a mouse until the late 80s. My Counting House GT2000 in 1982 had a lovely separate keyboard, I have never found another like it. All this while MS was still just some horrible nightmare, back when the latest machines had 12.5MHz 68000s with nice orthogonal architectures and running Unix ten times faster than the first IBM PC.
