Um, no. Well, if you buy a new one you will get a PA-RISC CPU but
that is not historically true. You need to look at the series number
to figure out what the CPU is:
500 - FOCUS (HP-proprietary 32-bit stack machine)
200 - 680[01]0
300 - 680[1234]0 (I think the 310 was the only 68010-based series 300)
800 - PA-RISC
400 - 68040
700 - PA-RISC
I think these days there is also a Series 600 that is PA-RISC and
a "T500" that is PA-RISC.
Some of these also have HP 9xxx numbers besides the "9000 Series xxx"
designation. If you go back and look at how they were originally
sold, the "HP 9000" was briefly just the FOCUS-based systems, which
eventually became the HP 9000 Series 520, 530, 540, and 550, and I
think I have seen references to the 9000 Series 520 as the "HP 9020".
The HP 9000 Series 226 and 236 were originally sold as the HP 9826 and
HP 9836; I believe there was some sort of upgrade involved for the
9836 that made it capable of running HP-UX (in addition to the
original BASIC, Pascal, and HPL).
