Hi, I'm currently working on an implementation of the Unix 6th Edition's filesystem for Linux. I think earlier Unix filesystems should be very similar to it. I would like to implement them, too, but I don't have exact descriptions of them (for the 6th Edition I've the Lions Book; there is not much about the actual filesystem architecture in it, but it should be enough - together with the code ;-). Please send me descriptions, specifications and everything else you've about the early Unix filesystems. Also filesystem images are very welcome as I can use them to test my implementation. My e-mail account can only handle attachments <3000KB. Please compress or split the files if they are bigger than 3000KB. Thank you Sven
