A relatively straightforward version of the well-known sharp boundary model is developed in order to investigate the ideal n=0 and n=1 stability of large aspect-ratio, high-β, tokamak plasmas with vertically elongated poloidal cross sections which are surrounded by either ideal, resistive, or partial conducting walls. All calculations made using the model reduce to comparatively simple matrix eigenvalue problems. Various example calculations are described.
