I have an A80 board with HDMI connector, so I can help with testing. Is there anywhere a list of which components are the same between Allwinner's SoCs? If not, I'll also accept pointers to pieces of information I can use to start a page on the wiki about it. How about the order in which the SoCs where released? -- Rask Ingemann Lambertsen
