It seems the MAME crew is rewriting a lot of stuff again and it makes no sense to fix any code that is just going to to broken by the rewrite. The design of the system is still a bit C oriented anyway. The HD6303 object should be able to inherit from the MC6801/3 object which should be able to inherit from the 6800 object... and then just overload things that have changed. The 6800/6801/6303 stuff hasn't quite made that transition yet. The built in I/O and RAM isn't even in the 6801/6303 objects, it part of the code for each machine.
I'll hack together a version of MAME using the timing table of the 6303 in place of the 6803 so I can perform some benchmarks and make a video or two, but until I see what changes are being made to MAME, there isn't much point in doing anything more.
