Changes
/* Instruction timing : talk about r005.8.16c20 */
Next step shall be destroying "PLEASE_WAIT" component I think, in order to add 1 WAIT_n and not 2 with my WAIT_n generator.
T80 WAIT_n has also to be checked, I know that inserting a WAIT_n seems generating a seconde IO_ACK edge during an IO_ACK.
Have to check also the moment IO_ACK is taken into account during M1 signal (I think it's at begin of it, but have to re-check that)
