Well, we actually used to use the little blinking lights on top of
the Cray-2 to troubleshoot system hangs. Since the mainframe was
totally immersed in Flourinert and had a limited number of test-points
for scoping signals, we could decode the LEDs to find out what the
last issued instruction was prior to the hang. Several other 
control signals were also viewable this way. 

BTW, I also decry the lack of bells and whistles on our current offerings.
