I have at least 1500 8" disks of various manufacture, density, and sides. Some are manufacturer's originals, some are well marked copies, others are marked in hand written Korean. Hundreds are marked in "user shorthand", and are probably quite un-interesting. Among the manufacturers I see are DEC, Altos, Microsoft, Digital Research, Pickles and Trout, Xerox and Tandy. There are also at least 30 CPMUG disks. I know at least one is a Scott Addams adventure disk for CP/M. I'd like to start inventorying them, dumping their content (using ImageDisk and the catweasel both), and trying to determine the "source" of the unknown disks. I know the usual warnings about these old disks: clean the drives, make sure they're not pinched in the sleeve, make sure there is no dust on the surface, etc. What other precautions should I take. Any and all _contructive_ advice welcome. Kelly
