Wanted: vacuum tube logic circuits

William> Over time, I've seen an occasional link here to an on-line William> copy of some 50's or early 60's electronic hobbyist magazine William> describing a binary project of one kind or another using William> vacuum tubes. If you have such a link or know of any William> bibliographical references to such articles that might be William> useful in obtaining a hard copy of the applicable articles William> via library-based research and inter-library loans, please William> post it here. I found some on Bitsavers. "Illiac design techniques" (under univOfIllinoisUrbana/illiac/ILLIAC) describes the basic logic elements, which are then just hooked together as building blocks (And, Or, Not, and flip-flop). Under ibm/sage there's a documents list -- only one of the documents is actually there but a lot more are listed, including circuit diagrams. Maybe those are available... There probably are others but those are a few I found quickly. paul
