Abstract: In this paper we study the set $\mathcal{M}_M$ of roots of power series with coefficients in $\{0, \pm 1, ..., \pm M \}$ and constant coefficient $1$. We prove that every nonreal root in the unit disk of a polynomial of this form is an interior point of $\mathcal{M}_M$. Moreover we establish a dimension formula and show the corresponding Hausdorff measure is finite and positive for a family of attractors parameterized by boundary parameters $λ\in \partial \mathcal{M}_M \setminus \mathbb{R}$. Finally we show that $\partial \mathcal{M}_M$ has Lebesgue measure zero.
