Next Month i will go to Alchimie, so i will make you a report...
On april, one dev said me that Mos 3.10 is probably the last main release for ppc, a bug fix will come after but the goal is to change, it's more exiting for devs to switch and to bypass all the limits of Abox. But he has not said me the ISA Morphos Ng will work on.
I have asked him if they continue to support Apple computers on the other ISA and the response was NO.
