who knows? pretty close to off the shelf versions, but no info about which one and what changes. They do run normal hc11 code.

Slight bit of a necro-post, but I have a bit of info that may help.

There is a flash-rom chip marked with what looks like "20964" and "2A914E" (first few characters obscured by cam flash) in the second picture.

I'm not sure if that's all of it though, since the PCM looks like it has 2 processors instead of just one.

If I'm way off base, let me know.
