This is indeed a nice project.  Somehow it's even a back to the roots thing.
Probably just a view people on this list can remember than some years ago
Neil Russel posted the idea of building such a board as accelerator for
Intel PCs to comp.os.linux.  The echo was overwhelming and soon a mailing
list for the "Riscy" project was created.

The original idea of the ISA card was soon droped and replaced by a
real motherboard.  Unfortunately the people on the list were unable to
find a common dominator of what exactly they wanted to build and after
almost a year or so the project died but was later on revived by some
people of the Waldorf Electronic development department with interest in
a MIPS system for both purposes of the company and in Linux on a real
hardware.  That much about history ...


A weird imagination is most useful to gain full advantage
of all the features - manpage of amd(8).
