So, it may, someday, have power, but it may not have any brains to do
much with that. We can still hope!

A great technical article about the IHU-2 onboard AO-40 is located at
http://www.amsat.org/articles/g3ruh/124.html, and dovetails into a
The Experimental IHU-2 Aboard P3D - AMSAT<http://www.amsat.org/articles/g3ruh/124.html>
Documents the design and development of an prototype spacecraft flight computer based on the Intel/Digital SA-1100 StrongARM 133 MHz RISC microprocessor.

presentation that our little AMSAT ASCENT group will be making at the
Symposium. See ya there!
