I did set up a little page with all the findings on the post mentionned earlier by linking *one* CRC32 to *one* part number, adding some of my own dumps and some other p/ns not mentionned (such as norwegian Workbench disks). I think this is really important since these disks were often modified and/or altered and having them well categorized in Tosec can be a great help in securing the original checksums for these disks. I'd like to take over this excellent work by Supamax that took the initiative to try to inventory the unaltered Workbench disks for the Amiga on this thread.
