Yes, it was called the programmer's switch.  One button triggered a 
non-maskable interrupt (NMI, useful for debugging), and the other issued a hard 
reset to the microprocessor (useful for giving up after unrecoverable errors).  
Neither was anything like the Power key, or the Eject button on Duo Docks that 
would shut down first.
