I'm in the process of writing a 68000 simulator.
Has anyone written a routine that will tell how many
cycles a given 60000 instruction will need to execute?
I want to pass this routine the hex code (1 to 5 words)
for a certain instruction, and I would like it to return
the number of cycles it will require.  The returned value
may be an upper bound, or up to 3 separate values if
the execution time depends on some condition codes.

If anyone knows of such a routine, please let me know.
