My preface to the manual: says v8 " incorporates facilities from the Seventh Edition, System V, andBerkeley BSD 4.1. The distinctive theme ...is distributed computing"It goes on to cite streams, Datakit, RFS, and Blit. The internet lurks in the citation of BSD 4.1. The preface goes on to suggest how the new facilities affected life in the lab: "These facilities have spurred a host of programs for remote information services, interactive graphics, debugging, and simple fun". On rereading this, I am struck by how blinkered I was not to overtly mention either the internet, which brought us out of the clumsy era of uucp and CSNET, or upas, which seamlessly integrated remote and local mail (and would eventually save us from the Morris worm). I recall expressions of surprise (dismay?) at the size of the BSD internet code, but without it we'd have lost our place in the Unix community. Even greater concern about the complexity of sendmail led Presotto to develop the simpler upas. Doug On Wed, Aug 9, 2023 at 9:09 PM Larry McVoy <lm(a)mcvoy.com> wrote:
