I wonder how many 1802's are orbiting the earth now?
The Galileo mission to Jupiter had a few 1802 processors on board (I 
read this a while back in an interview with one of the NASA scientists 
who developed the system).
Thank an 1802 for those beautiful images of the Jovian worlds Galileo 
beamed back to us.

More 1802 fun :-)
