ZDT is quite copyrighted.  It is available for some fee from Lifeboat
(sorry, that is the only place I have seen it.)  I bought it a while ago,
and I recommend that you attempt to find something else first.  Although
it does have some nice features (block compare, block move, etc.) and
I use it for those functions, it is a real pain to use for debugging because
it formats the input.  Instead of figuring out that 1F is 001F, you are
expected to type the whole 4 digit number in.  If you forget, it doesn't
work.  In order to list a segment of code, it makes you specify a range.
Thus, you have to do the computation to figure out how much memory would
fit on a screen.  I don't believe that I am overly lazy in not wanting to
have to think about such things when my energy should be spent debugging
my code, not guessing at memory ranges!
