I am trying to install this game without luck. My knowledge is limited with dos I have looked for any solutions to fix without any answers. I can get zork installed but no sound. When I get to sound config pc hangs then I get the message An internal stack overflow has caused this session to be halted. Change the stacks setting in your config.sys file and try again. I opened the config file and I do not see the stacks parameter I am running Phil's msdos startup file. I have had issues with other dos programs due to my pc being way to powerful. And have had success with either using slowdown utility or a ram disk. I tried both still a no go I got cpu down clocked to 60 mhz and left only 2mb of memory.
