@dcc Yes, computing hardware is controlled by the physical limitations of requiring fabrication equipment and the rare raw materials required for construction, therefore, free hardware doesn't yet exist.

There are some free hardware designs available, but getting those manufactured results in the same problems as hardware made from nonfree designs.

Running free hardware designs on a FGPA is a middle ground, but FGP's that are fast and large enough to handle all the logic required for a general purpose computer aren't programmable with only free software.
