(Sorry, that came across as somewhat snarkier than intended -- point being, the 3048A software expects to run on an HP controller or an emulator, and the emulators, in turn, can work only with full-featured GPIB controller boards. You're stuck with what the emulator author supports, and there's no way to make HTBasic talk to a Softmark or even a Prologix board.)
