Yup, I'm sure since I'm writing _to_ the REU, not fetching from it, so
there's nothing to overwrite. When I modify the code to write one page at
a time, I'm able to transfer the entire memory from $0000 to $FFFF.

I've enabled Bank0 which should be RAM0 all the way, although it shouldn't
make a difference whether I transfer all RAM or RAM+ROM+I/O.  When I come
home from work I'll post the source code so you can see what I'm trying to
do.
