No, no, no!  The C3 opcode set is the same as the 6801.  At least, all
the valid opcodes are the same.  I haven't checked if the illegal
opcodes behave the same way or not.

The P4 is like the HC11, except missing a few opcodes.

Neither the P4 (as in '165, '730, etc.) or C3 have the the I/O devices
that are included in an off the shelf Motorola microcontroller.
