For those with Xerox 820-II systems, Al has kindly posted a file on bitsavers containing images of a large collection of 8" floppies primarily for the 820-II (there are a few for other systems too) that I acquired a few years ago and just finished archiving this week. There is also an excel file with details on each floppy. These came from someone who worked as a software developer in the late 70s/early 80s and many appear to contain source code. Richard
