Is HP UX that it  runs similar  to what is on the HP INTEGRAL ?

HP-UX did a fairly extensive kernel rewrite, but implemented substantially
the same system call interface. This was apparent in a number of ways (the
binary format was different from other machines in ways I can't quite
recall, not quite COFF). They did ship mostly programs from BSD and SysV,
though through quirks of the legal minefield of the early days of Unix,
they did it under their System III license, at least in the early days...
Don't know if that ever changed to a System V license or not since they
didn't have a System V kernel...
