==== Instruction timing : talk about r005.8.16c20 ====
Instruction timing seems all respected following plustest.dsk, but I think it isn't enough, so it's still a candidate version.
Even prefixed and double prefixed instructions are taken into account by my WAIT_n generator.
WAIT_n generator is finally juste inserting a certain number of WAIT_n following executed instruction + a mod 4. In forum if I remembered, you don't do the next mod 4 alignement after a recepted IO_ACK (have to check that)
I try on this version to get an intelligent IO_ACK: in JavaCPC instructions just has a fixed time (array of instruction timing) and IO_ACK does not influence on them. So IO_ACK perhaps has to remove one WAIT_n inserted by GateArray.
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.
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)
