No, they do not run RTE. I don't think RTE ever ran on a parisc box
natively, although I believe there were some translator/emulator
code that allowed RTE binaries to run on parisc.

The 74x series boxes all ran both HP-UX and HP-UX/RT. HP-UX/RT is
probably what you were thinking of. It was a third party based real
time unix variant that HP modified to support some level of binary
compatibility with HP-UX.

They very definitely had a normal PDC and you should at least be able to
get serial output (as long as you set the console to serial) until the
Linux kernel switches from the PDC console.  As Matthew has already
mentioned, the 742 is pretty similar to a 715, so I think you should be
able to get serial output beyond that point as long as you have configured
the kernel for serial console.

I don't have any information regarding the VME bus. I believe there was
another HP proprietary bus bridge chip that would need to be programmed.
