I seem to recall an anecdote about Acorn hooking up the first prototype 
ARM-1 processor and it working, despite showing no current draw on the 
connected ammeter - it then transpired that the power supply was still 
switched off,  but it was so efficient that it was able to run via leakage 
current on the connected I/O lines.
