Abstract: We give a series of examples of simple finitely generated dimension groups which cannot be obtained as the inductive limit of a system

$\displaystyle {{\mathbf{Z}}^r}\mathop \to \limits^{{A_1}} {{\mathbf{Z}}^r}\mathop \to \limits^{{A_2}} \cdots {{\mathbf{Z}}^r}\mathop \to \limits^{{A_n}} \cdots ,$

where each $ A_{n}$ is a unimodular matrix whose entries are nonnegative integers.
