I don’t suppose you know of a teardown of the Intersil 6100 chip (also made by Harris)? Fond memories of using it in medical instrumentation—battery powered. Also with one of my fave books being Prosser/Winkel’s ‘The Art of Digital Design’ which builds a PDP-8 from scratch; it would be great to see how the chip did this.
