With AMBER6, remove the two variables above. With AMBER7 ndfmin is no
longer specified in the input. With these changes, the input file seemed
to run OK with my system.
Note that my debugging effort was simplified since some compilers /
namelist implementations are a little more friendly on failure and specify
what variable was not recognized. I tested on a SGI...

I do not have any references handy, but note that Zinc can be difficult
since the pairwise additive force field may not be sufficient to fully
represent its properties. Despite this, a number of MD publications have
used Zn and if you are mostly concerned with the structure, things may be
OK. A pubmed search (+molecular +dynamics +zinc) pulled up lot's of
references...
Good luck,
