I'm wondering how you could possibly get the signals synced closely enough for
this to work without a physical cable connecting the two RCX internals
(clocks??? I dunno). What is the cycle timing on these compared to instruction
clock rate? Even being off by 1% would, I would think, cause pretty good surges
of current, ne?
