I have a HUGE original issue service manual for the AT&T 6300 if anyone needs info. Everything from how to get the drive sled out(without damaging it) to jumpers, and even information on what certain error codes mean, as well as info on installing peripherals, and the jumper settings for them. Just ask for info as needed, and please don't PM looking for info on a certain part of the book, I would be glad to share the info with the entire forum! When I get a scanner, I will also be glad to scan the entir book(or section) for someone needing info. BUT if you really wanna see the pics in the book , I can always take a high res picture, as I did with the Seagate inst. manuals on a different post.
