It seems the invitation to join the rechristened Unix System Laboratories hasn’t gone out to all those developers et al at Bell Laboratories and AT&T Co as it was allegedly supposed to in the first week in July: seems AT&T want to be more secure about the shape of the company to which it’s consigning its workers, and is waiting to firm up its private placing plans first; a Unix System spokesman, however, said last week that the prospectus still hasn’t gone out; the company has also postponed announcing a bunch of strategic alliances, such as its multiprocessing partners, due now, until perhaps September.
