68HC16 a 6809 style cpu with 20 bit addressing

Has any body used the 68HC16 as general purpose computer.
Bank select style MMU. The nice thing is that you have a 16 bit
D and E register for 32 bit math.

I’ve never been able to find a design with sensible amounts of external memory and the righ tkind of IO as opposed to embedded stuff (same with the HC12)
