David, very brave work you do.
We should find a business case to be able to collect money on a crowd
So we *need* a product and a road map. The product needs to be catchy and
of a geek.
So as I wrote today, I strongly suggest building C64 spares, beginning with
as peripherals get broken most likely as they are exposed to
experimentation, e.g. user port.
How to package, do we have access to a package molding company or package
in order to put our chips into a nice DIL40 package
We can by a C64 and do reverse engineering by grinding and photographing
the layers of the
chips if needed.
Lets do DIL40 stuff first, as I think there is some quite easy money :-)
