We have had occasion to compare Intel's published 8088 timings
with actual 8088's.  The published timings are simply false.
They are VERY flattering.  In general, they claim instructions
take 2 clocks, where in fact most take 8.

The book specifically states that 8088 timings may be off by
"up to 10%".  We have found 80-100% to be closer.  Always slower.

I would take Intel timings with a very large dose of salt.
They are not exactly... well, come to think of it... they are
actually lying.  I hope they clean up their act someday.
