He explains in the first comment: A little clarification on Solitaire history. I wrote it for Windows 2.1 in my own time while an intern at Microsoft during the summer of 1988... ...A program manager on the Windows team saw it and decided to include it in Windows 3.0. It was made clear that they wouldn't pay me other than supplying me with an IBM XT to fix some bugs during the school year - I was perfectly fine with it and I am to this day.
