Anyone have manuals for these peripherals?

I have a Perkin Elmer VT2222 disk drive (Vanguard I) which due to the acquisitions of the time, was Interdata and became Wangco and Cipher. Looking for a manual especially schematics. I have an IBM 9347 (9 track tape drive) which uses IPI-3 for its interface. If I can get schematics for the drive (or for the controller board that goes in a 9370 system, I can get work up a replacement interface. Looking for the manuals for drive or controller.
