Make me a hack! Oop, I already am one] We are facing the incipient arrival of a 3Bnet (21 3B2's and a 3B20). This campus has never seen anything more sophisticated than uucp through hard wired terminal ports. (And even that didn't come into existance until last summer when I put it together). Our current hardware is: - 1 Vax-11/750 running 4.2BSD. - 2 PDP-11/23's (on the old 18-bit Q-bus) running 2.9. - 1 PDP-11/44 running 2.9. - 1 PDP-11/24 running 2.9. - Two Intel 80286 machines that just arrived and have no software as yet, though there is a bunch of hardware in each. - A Compupro 68K machine that will run Unix once the software gets here. - A 16032 board that may be made into a machine and run Unix someday (if we ever get disk/memory/terminals/etc for it). We are wanting to know the feasibility of connecting any or all of this hardware to the 3Bnet. From reading the 3B documentation I get the idea that it is ethernet at the connector. Would DEUNA boards attach us to this net properly (and appropriate equivalents for the non DEC hardware)? What's the difference between 3Bnet and the NSC HYPERchannel? (The programs for the 3Bnet stuff have the same names as the programs for the HYPERchannel stuff in sysIII and sysV.1). Is my impression that it will be necessary to write a protocol driver for use under 4.2 correct? Another consideration is that the University will, sometime during the next year, be putting in a broadband ethernet to interface all the machines on campus into one large network. We have to consider compatibility with that. (Sorry, I don't know if they have made any firm commitments to any particular hardware yet). Any information will be greatly appreciated. Especially appreciated would be pointers on books that cover the subject. If there is interest and response, I might be persuaded to summarize to the net.
