no expert at all; was before my time - But probably worth spending some time with ITS, TOPS-10, and TOPS-20 & digging around with TECO and its descendants which came to be emacs, and probably checking into 4.2/4.3BSD as well.. The former group is pretty much the platform for early LISP (when lisp was still in caps :b ), and the latter, well, alot of good stuff happened here.. plus built in franz lisp and the lisp mode for (real) vi ..
