I called the only place I know of that supported 3B2 stuff, which is Communications Hardware in TX. They recently had a change in technicians, and a lot of the older stuff they no longer support got culled, but they are willing to look for boards, drives, or whatever would help the collectors get their machines up and running again. I described the documentation set to them, and they will look for it. Any parts you want, send me a list, and they will hunt for me. Cindy Croxton
