Info-Vax mailing list messages previous to 1981

Hi again. I've checked CRVAX server but I can't locate what I'm searching... Anybody knows a place where could be located the INFO-VAX mailing list messages previous to 17-May-1981 ? This is the date of the first message gatewayed to the Fa.info-vax newsgroup. If I read correctly the info that appears in http://www.firstmonday.dk/issues/issue3_8/chapter10/ , Usenet began in 1979, and the FA.* groups were gatewayed (1994 if the RIP note of one person that I assume was Keith Bostic was correct) UCBVAX server. Do you heard about some kind of backup or so of these early Usenet and/or mailing lists messages ? By the way, a little swinging in the messages of these years is, like Spock could say without any doubt, "fascinating". By example, one reference to one Datamation of 1981 that did a critic about the Unix interface :-) ,,, or one guy that tried in 1981 to do one list of DBMS for Unix. I don't know if somebody knows cause of direct participation some of these hits. Thanks and Greetings Sergio
