[NTLK] Easy eMate CPU Light?

[Jim Lee]

Hook an LED (through an appropriate buffer/driver - like 74HC04) to  
one of the upper address lines, or the rd/ or wr/ line.  You would  
likely want to use a one-shot as well (e.g. 74HC123) to slow down the  
blink rate to something recognizable by human eyes.  Plenty of room in  
an eMate for such a circuit...
