This way to get out of the first room is straight out of Zork II. You have moved into a dark place It is pitch black. You are likely to be eaten by a Grue...
You have to get a screw holding up the flag behind the computer. Use the screw to open up the diskette box.
Great game. I just started it and did the first level. I have to run soon, but I'll be back for the rest. Thanks for the link.
