ABSTRACT
**

We have carried out extensive computer simulations of one-dimensional
models related to the low noise (solid-on-solid) non-equilibrium
interface of a two dimensional anchored Toom model with unbiased and
biased noise. For the unbiased case the computed fluctuations of
the interface in this limit provide new numerical evidence for the
logarithmic correction to the subnormal $L^{\frac{1}{2}}$ variance
which was predicted by the dynamic renormalization group calculations
on the modified Edwards-Wilkinson equation. In the biased case the
simulations are in close quantitative agreement with the predictions of
the Collective Variable Approximation (CVA), which gives the same
$L^{\frac{2}{3}}$ behavior of the variance as the KPZ equation.
