Govloop has this post, with a very young Bill Gates balancing a floppy disk on his finger. When I first saw it, I thought it was an 8 incher, but it's more likely a 5 1/4 one. As an 8 incher, it brought back memories of the IBM System/36, the minicomputer which ASCS used to automate its operations.
(Going even further back, in the early 70's there was a pilot project to put remote terminals in county offices. The storage at that time was an IBM 7.5 meg disk drive.)
