HP9000 Series 100 machines did not run HP-UX.  They ran HPL, BASIC or
Pascal.  These languages were usually stored on disks and loaded from
there, but you could also get the languages on plug-in ROM cards.

Series 400 machines were basically HP9000/Apollo hybrids.  The boot PROM
contained support for two different modes - one for DomainOS (the native
Apollo operating system) and one for HP-UX.

Series 900 is the HP3000 family of business servers.  These machines all
run MPE/iX, not HP-UX.  For more information on HP3000 and MPE/iX, see:

s300 6.5 and s800 3.1 were both replaced by a supposedly converged HP-UX
7.0, but, in fact, there were significant differences, and not just
because of the IO architectues.

HP-UX releases <= 10.20 have been removed from the HP corporate price list
(ie, they can no longer be purchased).

HP-UX releases <= 10.00 have been classified as obsolete (ie, no longer
supported by HP).  10.01/10/20 will be supported through June 30, 2003.

HP-UX 10.30 was a limited release intended for early access for 32-bit
kernel threads development and testing, prior to the release of HP-UX
11.00.  For this reason, it was discontinued and obsoleted fairly
soon after the release of 11.00.

HP-UX 11.10 was a limited release and is supported only on V2500 SCA and
V2600 SCA servers.  Prior to the release of 11.11, 11.10 came preinstalled
on these systems.  It was never available separately.

HP-UX 11.11 and later is marketed as "HP-UX 11i."  The "i" stands for
"Internet" and is meant to convey that the OS is Internet-ready.  Here
are the mappings from 11i versions to HP-UX versions as reported by
uname:
