I also jotted down some notes about the TENEX file system: https://gunkies.org/wiki/TENEX_file_system_layout I don't know what the internals of the TOPS-20 file system look like, but supposedly DEC rewrote or replaced the TENEX code. Among other things, TOPS-20 supports subdirectories, but TENEX doesn't. Chuck Guzis wrote: > Did Tenex employ the Rad50 file naming scheme? No, file names are in ASCII. Other PDP-10 operating systems use SIXBIT, not RAD50.
