Any PDP-7 Expertise?

Hi all. Some of you may know me as the guy who set up the Unix Heritage Society at www.tuhs.org. We've been able to restore some of the old Unix systems to working order, including a PDP-11/20 version from 1972. I've just been given a scan of the assembly listing for PDP-7 Unix which includes the kernel and some user-mode programs. The scans are at http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/ as the files 0*.pdf. I have this crazy idea that this system could be resurrected to working order on SimH and/or on a real PDP-7. But I'd a) need to learn the PDP-7 architecture, b) write an assembler, c) OCR the scan (manually) and d) spend a lot of time debugging something that has no user manual and may not even work! I thought I'd ask here if there is any PDP-7 expertise that I could lean on if I decided to actually proceed. Many thanks in advance for pointers, suggestions, help. Warren P.S I've already found http://www.soemtron.org/pdp7.html the PDP-7 Reference Manual f75ppdp7prelimumdec64.pdf and http://bitsavers.trailing-edge.com/pdf/dec/pdp7/`
