if you want to contribute, but don't have e.g. arcane knowledge of PDP 11 assembly and such -- then let me suggest that it would be interesting to find out more about these people listed in the 1973 "Study of Unix" documents (http://www.bitsavers.org/pdf/bellLabs/unix/) that formed the basis of this reconstruction effort. For starters, who was this "T. R. Bashkow" who called the meeting? Some googling last week indicates to me that he has an engineering award named after him, and that he does not have a wikipedia entry. B. A. Tague's name is prominent too, although I personally do not recognize it. And similarly for the other memo addressees. Consider that any of these people might just happen to still have source code listings, magnetic/DEC-tapes, paper tape, or even just historical anecdotes to share, but perhaps no one ever asked them. Or their heirs, for any who have passed on. In any case, it's getting kind of late in history; this may be the last chance to track down even information about these people who participated in this historic meeting, let alone find them and ask them about ancient media. P.S. The above thoughts apply to all other historic systems, of course, not just those Unix-related. I managed to find a RESISTORS-related historic document last week, for instance.
