You need to rebind the Prolog I/O to some character-I/O window. This is done for plwin.exe as well, and rather easy. Second is to deal with memory management for the stacks. Various schemas are available, and with good knowledge of what can be done in MacOS it should not be too hard, provided there is some way to allocate real big memory chunks (the biggest allocation contains both the local and global stacks).
