Is this Leonard Holmes?
If so, do you still have copies of your Amiga Crossing newsletters? (ideally on-disk)
I'd love to digitize those, and try to preserve them in the future. There are plans for a new area of the site to eventually host and support that kind of data.
Also - what's the main issue you're dealing with? Battery damage? FWIW, most A3000 don't usually require re-capping the way the later models do (600, 1200, 4000) unless there's a obvious issue, or you're just trying to give them a tuneup for the sake of it.
