'HMO (HückelMO)' from Arvi Rauk and Richard Cannings. This lets you compose a molecule graphically, generates the Hückel matrix and solves it in real time on your computer giving a graphical representation of HMO's and their energy levels.

'CNDO/2' program by Pirika company. It takes a MOPAC type molecular structure (3dimensional, example given), optimizes it and gives the final SCFenergy and the set of occupied and some unoccupied orbitals as a level scheme with orbital energies. A simple 3D orbital plot is produced as well. The PM3 hamiltonian is used. The applet is extremely fast.
