I have a disk image with HP-UX 9.03 installed, coming from an HP 9000/425t, and it worked (after minor tweaks) on my HP 9000/375. Now I'm recompiling the kernel, since some drivers are missing. I'm lucky, that image has a C and a Fortran77 compiler installed. Do you know if some HP-UX 9.x (or earlier) images can be found? I'd accept also DDS-x or QIC tape images... Thanks!
