Here is a walkthrough for Save Princeton. It is not a '100 % walkthrough',
I have left some small puzzles and guess-the-verb's, but they are easy to
solve (I think!). I would like to thank the people on
rec.games.int-fiction who spoilt me. Any comments are welcome by e-mail.

You start in the Common room. Take the disk and go south to the big
bedroom. Here you see Jacob. Ask him about the names and give him the
disk. Take the violin, go back to the common room and west to the small
bedroom. Give the violin to Eric and take the poster. Go back again and
leave the room to the southwest. Go upstairs and enter the girls room. Now
you know what the goal of the game is. Go west and take the hairdryer. Go
back, out and down and go west. Go north, west, north. Try to steal some
money here, go west and north. In the dining room, just take the glass and
the food-like item. The food smells so terrible, that you'll never be
hungry again, so you don't need to worry about food in this game. Go back
to Holder Courtyard, go north and down. Listen to the announcements on the
radio and check the couch. You'll find an important item here. Go up and
all the way south to Joline Courtyard, now go southeast, south and south.
Here you have to put your money in the tray to buy a USA Today (which is
totally useful, so please don't read it). Don't forget to take your
change!

Now go southwest to the market and buy one of the items which you have
enough money for (examine each item here). Leave the store and go back to
Joline. Go north and show the poster to the Jock (don't give it to him!).
Go south, get the dryer ready for use, turn it on and put the poster on
the manhole cover. Dry the poster. Go back southeast and southeast and
enter Whitherspoon. Knock on the door and use the glass as a hearing aid.
You'll have to solve this puzzle by yourself (I won't give the answer,
but it is for sale at the WaWa market) and then SAY "<answer>". Enter the
room and the only thing you'll need is the lava lamp. If you can't leave,
you'll have to turn off some things first. Outside the room you go east
or west and then you go east, east, east.

At Murray-Dodge you go down and north. In the bowl you find some dough
with which you'll need to bake some cookies in the oven. Go back to the
cafe and up, north, north and up or down. You are in the Firestone
Library now, wander around through the bowels and read some books, but
don't worry about the maze. After a while you'll end up at the
Photographic Services. Take the camera, go north, south, south and go
east, east and east. It's very unpolite, but take a picture of this
character and show it to him. Now you can examine his clothes and take
the wallet in which you'll find an important item. Go back to Outside
Whitherspoon, southeast, south and south. If you cannot enter here show
the ID-card to Otis. Here you'll see an exhausted athlete who looks very
hungry. So feed him! Take his reward and go all the way back to the
Tiger-Inn. Remember the anti-social character? Protect your head and
headbutt the lamp. Examine the debris and remember the code you'll find.

Now go back to the manhole. Dave, the tourguide fell into it, because he
was walking backwards. The tourists are lost but if you take the umbrella
out of the manhole they will think you are the guide. Go southeast, north
and east. Now enter Nassau and open the door with the code you found.
Enter the room and change the lightbulbs. Turn on the light. The guard is
now hypnotized, and so are you, but you are able to search through his
clothes. Wear the glasses and take the key. Read the tag and go to that
building (is it?). You can use a shortcut: leave the Nassau building and
go south and southeast to Whig Hall (You Think). Unlock the door and
enter. Here you'll find Hal Shapiro and go back to the room with the
burly guard. Leave the lamp on and enter the office. Don't forget to
protect your ears! Let Hal put the King asleep and blow the trumpet. You
have now saved Princeton!
