The new thing I learned from this is that not only could it track stars in daylight (which is impressive, but might not be that hard to do at 60,000 feet), but it could do so in daylight at sea level...with the processing done by a computer with 32KB of RAM (with the option to kick it up to 64KB). Wow....
