As I understand it the Shuttle still uses 386 computers, apparently the reletivly lare size of the internal structure of the CPU makes it less suseptible to cosmic ray damage.
I did not have time to read the whole article when I posted it, is it their intention to carry the CMS up in the Shuttle bay?, or launch it on a rebuilt Saturn 4B ?.
As I said I have seen a clip of Rutans lifeboat, it was dropped from high altitude and worked fine, so he must have been a long way along with the project, I wonder why it was abandoned.
