Dennis says: "It was pretty obvious many months in advance that the support was likely to go away, and the machine stayed around for months after." [[:publications:quarter_century_of_unix|QCU]] pg 8] **April, May, June:** Ken is interested in writing a file system. Dennis says: "The interest was older than this. He did experiments with simulation of paging on Multics, for example. He also wrote a rudimentary, completely stand-alone system for the Multics machine that achieved the equivalent of "Hello World" but gave it up when it became obvious that the hardware would not last." [QCU pg 8] **Mid-year:** Ken brings the file system to life on the PDP-7 in a month [QCU pg 10] **Unknown:** Ken develops the B language. Dennis says: "By the time B was developed, PDP-7 Unix was a 2-user system that already did a basic core of ancestral commands and was self-supporting (development done on itself). So during the next months, extending into 1970, a useful programming environment visibly ancestral to current Unix was developed. B was just a part of this."

 **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."

-**Unknown:** Ken has recoded the Unix kernel and some commands in PDP-11 assembly code. Dennis writes: "Much of the recoding occurred before the disk was delivered. The basic system was running and executing commands, with a basic shell, cp and whatnot. The 12KWords were divided into 8KB for the system code and data, 8KB for running user programs, 8KB for an in-memory file system. This all used a cross-assembler written in B that ran on the PDP-7 and generated the -11 object programs."
