Right there is your first problem. You need to make some money
otherwise you cannot provide PCBs assembled or otherwise for the
considerable number of people (i.e. 99% of users) who don't want to
(or can't) do all the assembly work themselves. Just the simple
problem of getting the CPU chips at a reasonable price will require
collaboration and someone has to organise that, and yes, I'm afraid
they need to make some money or they will give up after a few months
and go and do something else!

There is your second problem :-). You don't need the schematic
though. RDC themselves provide a reference design for the CPU which
would be the best starting point for a new board. They may supply it
if you contact them. I think it comes on Orcad files, if I recall.
