Documentation on the HP IPC

I have an IPC with HP UX 5.0 and HP Basic in ROM. The system has a built in HP-IB connector as well as an HP-IB expansion card. The system boots fine but I haven't had much success in getting the built-in floppy drive to read the floppies I have prepared (using a wide variety of systems and techniques). I am trying to use an external HP-IB dual floppy drive (an HP 9122D) but the IPC refuses to admit that the 9122 is connected. So, if anybody has tranferred images to a floppy, please let me know of your technique. I have PCs running many OSs (from MSDOS 5.0 to Windows 2000 and OpenBSD, FreeBSD and Linux). I also have Sparcs with Solaris 7 and OpenBSD. On the subject of documentation. If anybody has manuals for this machine please send me a note. If you don't want to part with them I can pay for photocopies. It is very frustrating to have the IPC just standing there when I *know* I can get it to work. Thanks **vp PS I suspect that the built-in floppy is double sided-double density, but anybody knows block size, interleave etc. of these diskettes?
