The 9000/779 seems to be like an RDI PrecisionBook:

which is quite similiar to a B160L.

There is even an entry for your logic analyzer:

In qemu the B160L emulation isn't complete yet.
The SCSI disc is emulated by a "virtual built-in" PCI SCSI card, while
the original B160L has a NCR 53C710 SCSI chip internal in the LASI controller.
Additionally the LASI emulation isn't complete either.
My assumption is, that your Install CD for the analyzer will only detect
real LASI/53C710 chips and ignore the virtual PCI card. That's why it doesn't
detect any discs.

You could drop the "nochain", it slows things down.
Without "nographic" the STI framebuffer might work.

both are on the virtual PCI card...

That's strange.... I think 8/... might be LASI.

I'm not an HP-UX expert.
Maybe it's possible to install HP-UX from another install CD and
install the Analyzer packages afterwards?
