I should like to have instruction timing data for the Motorola 68010 and
68020 in a machine-readable form suitable for use by a program.  Where can I
find it?  I realise that caches and pipelines make the figures imprecise;
worst-case figures would probably do for my application.

More generally, which manufacturers provide machine-readable information
about their machines?  For instance, many people must have to type in the
instruction code tables for use in compilers, assemblers, and linkers.  This
is tedious and error-prone, yet each manufacturer must presumably have done
this once, and could make the tables available in some form for others to
use.  Perhaps they all do!
