Calmos (then later Tundra) Semiconductor actually documents them in detail in their CA80C85 datasheet, but those were from the early 1980s. What was interesting was that even through we were working pretty tightly with Intel in 1976, not a word of the added instructions was uttered by our sales guy, "Fast Eddie", who usually was pretty well informed about the goings on over in Santa Clara. Bill Davidow was on our BOD as well. That's a shame; we could have used those instructions too. --Chuck
