Hello, folks! I had an old Commodore 64 adventure game hint book and one of the walkthroughs was for Questprobe featuring Spirderman. I thought I'd upload it somewhere for posterity, before I throw out the book. Since I can't attach the file, I'll just copy/paste the text:
SPIDER-MAN
1. Climb Ceiling. Look in Crib. If Sandman comes up go East, return. Take Formula while Sandman is still sand. Leave and reenter. Take Gem (from crib). Climb Down.
2. Drop Gem. Type Score. Say Scan (object or person) to Madame Web.
3. Open Doors. Go Shaft.
4. Look Elevator Walls. Look Niche. Take Gem. Do this at each of the four landings of the elevator. Push Up at the third landing to get to the fourth.
5. Take Painting. Remove Frame. Get Formula. Lower Thermostat. Do it again. Open Desk. Take Gem.
6. Get the Acid, Calcium Carbonate, and Acid in the room to the South. Mix Acid with Calcium Carbonate. Get Calcium Chloride. Make Fluid.
7. Close Eyes. West. Push Knob. Open Eyes. The RingMaster is now gone. Get Gem. Type Run for a clue.
8. Give Calcium Chloride to Lizard, Search Doc. Get Gem. Take Doc.
9. Look West. Shoot Web at Bio-Gem. Drop off your Gems with Made Web to avoid inventory problems. You should now have nine of them.
10. Go back to Hydroman. Get Ice Block (Aquarium). Get Statue (Hydroman).
11. Drop off Ice Statue outside. Take All (the Desk, Clock, and Couch). Raise
Thermostat (twice). Look Aquarium. Take Gem from Aquarium. Lower Thermostat. Get Statue on way out. (Statue again becomes Hydroman when Thermostat is raised. Don’t ever drop him as Hydroman or you’ll never get him back.)
12. Jump.
13. Feel North. Get Gem. Feel South. Get Gem. Climb Ceiling.
14. Open Mesh. Enter Duct.
15. Drop all Gems temporarily. Examine Fan. Shoot Web at Fan. Examine Fan. Speed will be down by 100. Shoot Web at Fan until speed is 50. Shoot Web at Button. You could stop the Fan by throwing a heavy object at it, but you need them all later. Enter the Maze with Enter Fan. Get Gem. To get to the Basement go Down 5 times. (To get out, go Up until you are at the back of the Fan and then Enter Fan.)
16. Get Gem. Take Dr. Octopus. Hit Electro. Search Electro. Get Gem. Search Dr. Octopus. Get Gem. Drop Gems. Take Electro. Take Dr. Octopus.
17. Put everything you have on scale, including the Hydroman, Electro, Dr. Octopus, Doe Connors, Couch, Clock, Desk, and Mesh. Read Dial. It should read 951 pounds. Go to Computer Room. Get the Gems you left earlier.
18. Type Run. Go back to the Basement and Get Newspaper. Read Newspaper. Take Newspaper to the Computer Room. Type Reset. Get Gem.
19. Drop the last of your gems with Madame Web. Score. You should now have 18 gems worth 100 points and a password to some future game.
