[Coco] Un-upgraded 3124 Multipak/Coco3 Question

[Mike Pepe]

I second that. Essentially the MPI and the GIME chip will respond to the 
same addresses. Reading is probably the worse of the two in terms of 
potential damage, since the GIME and MPI will be driving the data bus at 
the same time. It could potentially kill the GIME. Not likely, but it is 
possible.
