I'm hoping someone can help me out with this vintage 1980s microcontroller - the Motorola SC44125P.
It is clearly an OEM version of a 6800-class microprocessor (see attached picture for pinout; the highlighted pins are those that differ from a stock MC6800).
The information I am after specifically:
Confirmation of which MC6800 variant this chip is based on (6800 / 6801 / 6805 / 6809 etc.), so I can look up the correct opcode table.
Presence and size of onboard ROM and method by which said ROM can be read out.
