Deciphering markings on a mask-programmed HC11

I've had this board kicking around for a while that has a Motorola processor on it (in a PLCC-52 form factor).

I recently realized that it is actually a mask-programmed version of the 68HC11E9.

There are some additional markings on the chip, and I just want to verify that they would include the firmware that would have been masked into the chip at the time of manufacture.

Note: Some information on this thread has been removed as it may contain sensitive information.

I don't even have an authorized rep. I'm just a hobbyist.

I eventually got my answer elsewhere.
