Nope, I've got complete schematics, and a dump of the EPROM. It's going to take a while to figure out how the heck why it's hallucinating a power failure (the signals going into the CPU are appropriate).
Oh, it has a ROM, just on an external chip. I misunderstood your original post. I thought they had somehow programmed the device without using ROM at all, which made it either very old school or very custom.
