[TUHS] Unix Sixth Edition Boot Loader Analyses

All, I just finished some compact analyses on the boot loaders that are presented in "Setting up Unix - Sixth Edition" by Thompson and Ritchie. They are in followup to the more detailed analysis of the Tape Bootstrap Loader that I mentioned previously and the entry is posted here: http://decuser.blogspot.com/2015/12/pdp-11-bootstrap-loaders-some-analysis.… What was most interesting about the analyses and programs was how related they were. At the end of the day, once I understood how the first one worked, the other two were pretty simple and required only minor tweaks in the coding to achieve their results. I am moving on now that I have a pretty good idea of how these bits of code work and will be starting to program in Macro-11 for a few weeks to get a handle on things before I return to the deep dive into the source code of v6 that I temporarily put on hold so I could actually make sense of the Assembly bits. I really appreciate everyone's help, tips, suggestions and even critiques. Thanks, Will
