The Connection Machine has an LED for every 16 processors...
That 512 for each 8K corner cube...A 64K machine must have
4096...

The CM looks really neat with its LEDs on.  The programmer can
(from C/PARIS at least) specify what data in each processor
group the LEDs represent.  There are also modes which make the LEDs pulse
to the system clock, or just stay on continuously.
