root zone archive

Hi all, Is anybody here aware of a complete or partial archive of root zone data that is older than the set available at DNS-OARC? OARC's archive has nothing older than July 2009. I'm particularly interested in zone data that describes the build out of the original root zone NS set to nine servers in mid-1994, the renaming under the ROOT-SERVERS.NET domain and the subsequent assignment of J, K, L and M. I realise this is a bit of a long shot, but the answer's always no if you don't ask :-) [I'm asking the same question on a small handful of lists; apologies if you get multiple copies of this.] Joe
