Hi all, Norman Wilson has kindly scanned in some PDP-7 Unix source code that he has kept hidden away. I've just added it into the Unix Archive at: http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/ I've updated the Readme with the details. The files are 0*.pdf. I'm not sure if there's enough there to bring up a kernel and some applications. I'll leave that to someone who knows PDP-7 assembly programming :-) Many thanks Norman! Cheers, Warren
