There’s 10 extra index holes (the small hole next to the big centre hole) - if you spin the media inside the jacket, you’ll see a whole stream of index holes instead of just one per revolution. This is a very onerous way of finding them. The label will probably say something about being hard sectored. But unless you know the collection of floppies came from someone who owned a very small subset of antique computers (basically the NorthStar Horizon or the Heathkit H8 I think) then there will probably not be any there. As for the hole punch, I heard that someone built a jig to rotate the media the correct number of degrees in order to punch, but that is a lot of work :) Ian -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
