Whenever I find old kit, I look around and ask around for any and all manuals, documents, whatever. As for complete, here's what I'd consider "complete", for, say, an 11/40 (like the one I got last year): - complete printsets for all boards etc, a pile about 6" to 12" high. - complete set of diagnostics (XXDP) listings, 12" - 18" wide on a shelf - manuals for the CPU, bootstrap loader, DL11-W, etc etc, 6" wide - technical manuals ditto for the RX02, RK05s, etc, 6" - 12" - manual set for RT-11 or RSX-11 and languages etc, 20" - 40" of shelf space - IC and other components references, Texas Instrument TTL handbook, etc, etc - probably other things I've forgotten. That 11/40 came with some of the original logbooks but not the invoices etc. My 11/34 even had some of the original orders and invoices, installation sheets, and the like. As for the suggestion someone made that you can get documentation from the web, well, that's sometimes true, but often the information is incomplete, or in an unsuitable format, or disappears after a while. I can't count the number of times I've been grateful that I downloaded a copy of some document onto one of my own hard drives, because the original online version has gone. Besides, a printed copy is often much more useful, especially for circuit diagrams and large manuals. -- Pete Peter Turnbull Network Manager University of York
