You may be suprised, but your local friendly Intel office should be able
to provide databooks FOC, which do contain this info. These may not be to
everyones tastes, but they do give a lot of info. They get better as the
processor progresses - the 8086 is (almost) readable, whilst the 486 book
is better than most commercial guides.

At least they shouldn't cost you anything (singly, that is. If you get them
bound together there's a charge.....)
