Subject: How to use Mem. mapping.
I recently received the Godbout CPUZ in the mail and after reading the
docs. I've
run into a problem. The memory mapping capacity (write to port FDH to set the
high order address lines) will switch the whole 64K out to another. My
question
is that if all 64K are out where does the next instruction come from??
I assume it
comes from the new bank but how do I get it there in the first place.
This seems
to be another dog chasing it's own tail routine. It isn't obvious to me
how to use
this facility. Anybody who knows how to do this or how this board works -
PLEASE message me. Thanks.
Tracy.
