 **Dennis says:** "I think the Neumann connection was an invention of my own fevered brain. I wasn't sure who created the name and I assumed Peter because of his propensity for puns. He has since denied involvement and Brian has claimed it, so I think things are as certain as they can be at this point."

+** Mid-year:** The PDP-7 version supports two concurrent users, one on a teleprinter and the other on the Graphics-2 device. The filesystem has the "dd" directory, a "system" directory for binaries and per-user directories, but no concept of pathnames, "." or ".." [ [[https://github.com/DoctorWkt/pdp7-unix|extant source code]] ]. Utilities include as, bi (B interpreter), cat, check (filesystem checker), chmod, chown, chrm (remove files), cp, db (debugger), dsw (delete from switches), ed, ln, mv, sh, stat (ls-like output on one file).
 **Mid-year:** The PDP-11/20 is ordered, but it arrives with no disk drives as they were not ready yet [ [[:publications:quarter_century_of_unix|QCU]] pg 35], [ [[http://cm.bell-labs.com/cm/cs/who/dmr/hist.html]] ]

 **December:** The prestruct C compiler sources. This compiler assumes a load address of 0, unlike last1120c which has 040000. This implies that the kernel now used the 11/45 memory management.
