I'm looking for copies or scans of any classic Stern Electronics service bulletins numbered #17 or above.
I recently stumbled across service bulletin #23 for Flight 2000, so it stands to reason that there are likely others in between, and possibly beyond that for games that were released after Flight 2000.
For several years, I've been slowly adding every bit of documentation I could get my hands on for every manufacturer and add it to pinwiki as one central, convenient location.

Service bulletins #1 through #16 are included in the 1979 Stern parts catalog.
Stern did not appear to have classic Stern Electronics documentation on archived versions of their website; they only listed service bulletins as early as the Data East & Sega era.
