Still alive! Quick update!

Well, it turned out this TLCS-870 was probably only the power management controller, and a very nice red herring. Whoops.

However, we have some suspicion about a Renesas chip on the board, also a uC, which might be the real embedded controller. We still need to start messing around with it, but we're both out of time, as usual. However, do expect some differential power analysis side channel attack stuff soon. Very soon.
