Looking interesting.
Just curious though, why ddr3? Given the low speed of both the cpu core and ram (relative to modern computing) wouldnt ddr2, or ideally ddr1 be a better match? Given the high latency of ddr3 Id expect the other RAM types to perform better. Is it simply a matter of availability/price?
I guess this is what the sockit board provides. We will have to live with it. :-)
I think this roadmap is a realistic plan to give first accel and then replace genuine amiga components piece for piece that results eventually with a standalone alternative system
