Hi Lars,

You link because v0 doesn't have a current directory when you start, and 
it's not a hierarchical fs, but rather a directed graph. Subdirectories 
are a pain. (the user guide explains it better)

Here are some links:

The unix 'user manual':

https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/UnixEditionZero.txt

The pdp7 user manual:

http://www.bitsavers.org/pdf/dec/pdp7/F-75_PDP-7userHbk_Jun65.pdf

Some miscellaneous docs:

https://github.com/DoctorWkt/pdp7-unix/tree/master/misc

The file asm_syntax is particularly good.

Later,

Will
