A Digital Printing Network
Are you sure there's nothing else on the disk that will enable you to read the database?
Have you checked the web under .fbd file. I don't know if it would help but I saw some about converting and opening this type of file.
If you can send me just that .fdb file I'll give it a shot-I'm running all Macs but there are some up to date emulators that came with it-worth a chance! I've never heard of that kind of file but you never know what might open it.
I googled .fdb just to see what it is and found this, along with a download app for Mac that may open it.
