You are welcome! :-) Regarding the PDP-8, have a look into "Computer Engineering" by Gordon Bell, Craig Mudge and John McNamara; DEC, 1978. (Quite common to find at a reasonable price, there are even some PDFs circulating, which may be found by your search engine of choice.) Edit: Maybe also of interest, "Computer Structures: Reading and Examples" by Gordon Bell and Allen Newell (McGraw-Hill, Inc., 1971). For availability, see above.
