You know, you get points for reading the book but lose points for buying a Rainbow :-) (kidding) Fortunately you didn't buy the PDP-11 version which ran the "Personal Operating System" (which was a lobotomized version of RSX-11, and aptly abbreviated to POS)
I agree that its a great book, these days it would be much less dramatic with everything running on simulators prior to chip tapeout.
Haha, the Rainbow was a skip-rescue, as was the PDP (which rain RSX-11M). Even came with the "orange wall" of manuals. Made a nice space heater, and we had fun running RS232 all over the house to attach terminals to it. Sadly it didn't have a compiler, only Macro-11...
