The primary reason (from what I've been told) is that many 7.x installation procedures rely on the "system type" field to determine the system CPU type. Historically, if the character following the slash is '3' then the CPU is a Motorola-MC680x0; otherwise it's a PA-RISC CPU (or maybe a S500, but that's just noise to this dicussion). The 375 internals are sufficiently similar to the 68030-based Series 400 systems that "backward compatibility" was deemed more important than "truth in advertising." It is my understanding that at HP-UX 8.0 the required effort to make install procedures aware of Series 400 systems has been spent, and therefore uname will return the correct system type (abbreviated to the 8-character limit). For example, a 9000/400t (desktop S400 with 68030 CPU) will return 9000/40T to a "uname -m" command, and a 9000/433s (deskside/server S400 with 33MHz 68040) will return 9000/43S. I'm not positive about these "facts" (or, in truth about ANY "fact") but I'm reasonably confident that this is the case. Hope that helped some, -Chance DISCLAIMER: I speak only for myself. My comments are most likely worth what you paid for them.
