Hi, I am looking for VAX Hardware Reference for the VAX 11/780, 11/785, 86x0, the uVAX-II, and then the VAX 6000s. I suspect that's not all in one book. But, what revisions of the Hardware Reference are there anyway? I think the first edition is the 1978/1979, at least my VAX Architecture Handbook bears this date. I understand that the "Handbooks" were a 3-volume series, with volume 1 Architecture, vol 2 Harware and vol 3 Software (VMS). I assume that they threw out old models in more recent editions, right? Could we reconstruct which topics are described in which edition of the Hardware Handbook? One can't buy those any more, how does that influence the right to compile and share copies? I wonder if one could archive the Hardware handbooks by subject and that way compile a single volume with complete coverage of all VAXen. Besides, there is a mystical "Perepherial Handbook" to which I have seen reference once, but never any copy in bookstores, catalogues or on eBay. Did it ever exist? Was it volume 4 of the series? What items were covered over the years in there? regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
