Hi I remember about 1971 collecting a PDP-8 I was going to use to use for control/data capture on a experiment at Harwell. It struck me then why supply such cheap manuals with a multi thousand dollar well built computer system? It was obvious that the books would fall apart if used. I had our repographics people take the books apart, blow them up to A4 and loose leaf bind them. They used research report archive paper (rot proof, fire resistant and good for 100+ years) and as a back up microfiched them as well.

Hi, Actually, my 1979 onwards PDP-11 handbooks are fine. They're printed paper which looks slightly glossy and haven't yet started deteriorating (noticably anyway). OTOH, my early/mid 70's PDP-11 and PDP-8 books are smouldering nicely.... ;-) TTFN - Pete.
