Ok, I popped the lid here... after realizing it's able to be opened withoud
desoldering. I take it back... There are several 33.2 Ohm resistors which
are wired suspiciously like heaters This now is starting to make some

If I remember correctly (I might not), they wanted the CPU to hit a

Just throwing this out there, but don't the epmp's have a small heater in
