[Coco] Test

I once suggested to someone on this list that the HC12 
could be used, but I was informed that it lacked certain 
registers.  I then suggested that a FPGA could be added to 
the circuit so as to add these registers.  I believe the 
person I was corresponding with thought I was suggestng an 
FPGA version of the HC12, since their next comment was 
that Motorola is very protective of the HC12 and would 
crack down on any FPGA version. 

An FPGA version of the HC12 was not my plan, but instead 
an FPGA augmentation of the HC12.  Basically use the HC12 
as a core processor tied to FPGA's so as to simulate a 
6X09 or   6XXX9 varient.  I don't know how clumsy that 
would be, maybe others would have a better idea.
