Thanks for the info, padgett; that means that my experience with a thrown cam magnet preventing start on the '88 Le Sabre was not relevant to the '88 Bonneville. Now I'm beginning to wonder if the engine in that '88 was original. I sold it last year so I can't easily tell. It is hard to believe they used different PCMs on Buicks and Bonne'* in 88.
If I ever get my current fires put out, maybe I'll research the diagnostic protocols on older 3800'* to see if ANY of them would produce a no start condition with a thrown magnet. I used a great Chilton'* book that I checked out of the library and have not seen since, that was titled something like "electronic engine controls and diagnostics." It covered the earlier 3800s.
Anyway, thanks for the info. And kudos to you 89bonnevil for getting it done and letting us know.
