Hello all. I purchased a non-working Strange Science last week that had not been used (or cleaned) in some time. Would estimate 5 years of filth). It may be the dirtiest pin I’ve personally seen. The GI works (the bulbs not burned out... which is about half) but it will not start a game. I’ve already stripped the playfield and need to do a lot of cleaning, adjusting, and parts ordering.

This keypad that hangs next to the launcher inside the coin door seems to potentially hold the key to getting this game going. I downloaded the parts manual and the tech manual, but can’t seem to find any information on how to actually use the thing. The tech manual PDF is actually missing some pages this keypad is said to be discussed.
Does anybody have a good pdf or link they could provide me so I can try to educate myself on how to use this? I’ve only found little tidbits on pinside and was hoping this specific community could maybe help give me some help in the right direction.

The owner said the keypad was how they got it on freeplay but mice literally ate the corner of the manual he had hand written the necessary codes.

When the machine is turned on the neon topper turns on quick then shuts off, The digital display says “1-4 can play on the left displays and something else on the right displays (maybe insert coins)?? Can’t recall.

The coin door has no mechs but does have the wired switches, but those switches will not add a credit and I’m not even sure if the keypad is functional because apparently these things were manufactured somewhere between here and hell.

Would love to read up on this while I’m doing the basics of rebuilding the playfield.

Thank you all!

I’ll give this a look through. Thank you for the direction!

I’ve read that in several spots that this game is horrible for flippers. Complete flipper assemblies (with coils) are planned.

the link provided didn’t take me to a usable location. Any change you could try again? Though I went to the “IPDB” site For the copy I have with the missing pages. Humm...

I’m struggling with this too. I have the parts book, but they list “13-digit” part numbers for everything and none of those numbers come up in the online parts stores like Planetry, Pinball life, Marco, etc. Is there a conversation I need to do or only search on specific digits? Most parts I’m looking for I think are pretty common; flipper rebuild, switches, and ball guides. What are you experienced guys doing with these long 13 digit hyphenated Bally parts book numbers?

I searched Google with Bally and the 13 digit part number. I was pleasantly surprised how many items came up! Only thing I couldn’t find was a wire form ball guide (glorified super thick staple) and I think I’ll just make one and have it powder coated with my other parts from the game.
Thanks for the tip! I would have never thought Google would find these numbers on the same pin parts sites where I already used their search. These same parts also were not cataloged against “game specific” category... so Google to the rescue once again!
