Being and old man, the sorts of things I have to look up tend to be whether signal XYZ is positive- or negative-going, or whether a counter counts up or down, and not how many nanoseconds elapse after signal A before signal B is valid, so whether it's NMOS, HMOS, or CMOS doesn't seem to have as much impact as it once did.

That spec might be adequate.

I am interested, though, in what everyone uses at "the Bible" WRT the 805x. There are so many scions, each slightly different from the others, that I'd suspect it's become difficult to discuss them monolitically.
