Alright, so AMF's website does not have all of their manuals available for download, however they do have the parts catalog for the 82-70. There are manuals and other parts catalogs for their newer versions of the pinspotter, such as the 82-90, the 82-90XL, and several more just to make it confusing for the rest of us. I'll do my best at organizing this mess.

Manual -- Coming Soon!
Stay tuned, because I'm still reorganizing all of these manuals right now. I'm trying to figure out a way to merge the individual sections into one big PDF file instead of these smaller ones.
