What do "V6" and "V7" refer to here? There was only one tape sent out with the Sixth Edition of the UNIX Programmer's manual, so in that sense there is no such thing as an "early" or "late" V6. I consider the main things that distinguish V6 from V7 to be the file system (and system calls changed for the new file system) and the Bourne shell; System III had that (heck, UNIX/TS 1.0 had that). As such, I consider them derived from a system between V6 and V7, but closer to V7 than V6. Guy Harris {seismo,ihnp4,allegra}!rlgvax!guy
