Was there an HP-UX "version 5" for anything other than the s500?
By the time I came to it, s300 and s800 were the only architectures
getting new development, with the s300 using 6.x version numbers
and s800 using 1.x. I never worked with s200, and I think the MODCAL
kernel was exclusive to s500.
And yes, the s500 userland was largely a System V userland (with some
BSD parts) built from C sources.

BWAHAHAHA!
HP-UX v5 is a rewrite of the System V kernel in HP's proprietary
MODCAL. ?It runs atop another lower-level OS called SUN OS.
It's pretty amazing in the sense that you can do that to Unix and
it still looks and works like Unix. ?Well, mostly. ?There are
some funny things about '.' and '..' on HP-UX v5.
Interesting. A lot of the stuff I've seen seems to indicate that the
SUNOS and Modcal stuff was for the FOCUS-based 500 series releases,
while the 68K-based releases for the Integral and the 200 series were
a bit more generic. If the 68K stuff also used the proprietary HP
stuff, that just makes it more interesting. Still the presence of Sys
V userland components still mean that you'd need a Unix license to use
the thing...
