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.

"Power for the basic computer consists of
one 250 kva, 400 Hz motor
generator set. The motor-generator set has the capability of providing
power for the CPU, MCS, I/O and the MCU. The optional memory requires
the addition of an 80 kva motor-generator set."
I'm looking at this RISC-V board sitting here on my desk (with its
"massive" 2-inch-long heat sink) and shaking my head at how far we have
come.
