Yeah sockets, FFS, VM, autoconfiguration. It almost seems a shame he went to SUN. Although at the same time it’s no wonder why they grabbed him ASAP. I guess it’s like Avie working for NeXT.

Hi Arnold, Özalp Babaoğlu, a Turkish name. https://en.wikipedia.org/wiki/%C3%96zalp_Babao%C4%9Flu -- Cheers, Ralph.

Reiser added paging and it was working well by early 1981. -rob On Thu, Aug 29, 2019 at 4:41 AM Doug McIlroy <doug(a)cs.dartmouth.edu> wrote: > > > Doug McIlroy <doug(a)cs.dartmouth.edu> wrote: > > > >> > >>> How long was research running on a PDP-11 and when did they move to a VAX? > >> > >> London and Reiser had ported Unix to the VAX, replete with virtual memory, in 1978.

I could've sworn 4.x BSD supported Micom Internan NI1010 or some other early ethernet like 3com as well as the DEC boards.

William That’s right. 4.1a supported at least these plus the original Xerox 3m card and I think a card MIT made for chaos and the protean card. iirc. We had one of each of the production 10M Ethernet cards in the cad lab at UCB at some point. The machine dec gave us had a dec card and that was the only dec card on campus so Sam would come over to my lab to test new OSses on that system. UCB originally bought 3com cards (eventually in the cad group I got some early interlan cards from their ceo to test and I remember we liked them better for some reason I don’t remember). Before we had the 3COM based 10M link, we had couple of 3M Xerox cards on the original link back to Evans hall. The Xerox cards were used with the BBN tcp before 4.1a. Eric cooper brought all that up with Sam and Bob Kriddle Iirc. That was all switched to the 3com cards pretty early to get 10M and Early after 4.1a and I do remember sam and I had used all that to debug Routed as we had the CAD Ethernet in Cory Hall, the back link to Evans and another Ethernet in the Evans machine room.
