Hi all. I have a bunch of old HP workstations including (as returned by
a `uname -a`) some 715s, 720s, 730s, one 777, 712s, and 735s. Now I know
the 777 is a C110 but I am wondering what the relative age/power of
these differant systems is. Most of the 720s, 730s, 735s, and 712s are
running HP-UX 9.x and I want to just swap them out of people's offices
for 715s already running 10.20 in order to simplify the process of
making them ready for Y2K. But are the 715s more powerful/modern than
the others? Is there an HP web site that has this "lineage" information?

Hi Mark,

I don't know the "geneology" of the other systems but I have a 715 myself.
As far as I know the 715 comes with a 50MHz PA-Risc CPU (Upgradable to
100MHz) and 16 or 32Mb internal memory (upgradable to over 300Mb).
Hope this helps.

Here is a list - with what I have from 1996:

System Spec int92 MIPS
712/60 67.3 73
712/80 99 92
712/100 115 125
715/75 93.9 92
715/64 81 77.7
715/80 99 97.1
715/100 115 121
725/75 93.9
725/100 115 188

I do not have the info for other models.

Hmm, time to set the way-back machine...

The first 700's were the 720, the 730 and the 750. The 720 had a 50
MHz PA1.1 CPU, the 730 and 750 ran the same CPU at 60 (66?) MHz. This
was before processors were called PA-NNNN. The CPU was the PCX-S
CPU. The same CPU used in the 8X7's. The next 700's were the 705 and
710, which were stripped-down, cost-reduced versions of the 720 IIRC.

Then came the 715/50 and 715/33 and the 735 and 755. These used PA 1.1
CPU's called PA-7100. This was also known as the PCX-T CPU. There was
later a 715/75 based on the same CPU. The 735 and 755 ran the CPU at
99 MHz, the 715 at the speed indicated by "/NN." The 715/33 replaced
the 710 and 705, and I think the 715/50 pretty much replaced the
720. The 735 and 755 replaced the 730 and 750 respectively.

Somewhere after that was the 712/60, the 712/80 and the ill-fated
712/80i (crippled floating point). These used the PA-7100LC (Low Cost)
CPU, which put a bunch of functions on the same ASIC with the
CPU. Around the same time came 715/64 and 715/80, which replaced the
other 715's.

Also around this time, the 735 and 755 (?) got frequency boosts up to
125 MHz. This was probably (?) near the time the 715/100 was
introduced. I think a 712/100 arrived around the same timeframe.

Around this time, just calling a system a "7XX" is not considered
optimal. IIRC this is also the time the 8X7's (Nova's) started
becoming F, G, H, and I's, but I am not certain which started
first. Letters were also becoming fashionable in other spaces - cars
for instance.

In the "800" space, we are starting to run-out of numbers - 800's had
been shipping since 1986 or 1987 or so. there had already been a series
of 8X0's, 8X2's 8X5's, 8x7's.

The decision to start using letters was primarily a marketing
one. Software was still dependent on knowing if a system was a "700"
or an "800" so systems still needed to be given a 7XX or 8XX model
name. Now things start to get "interesting." I must confess that I
have no idea what the mappings are - and it is entirely likely that
the mappings are not quite unique.

The C100 and C110 came-out to replace the 735's. These ran PA-7200
CPU's (I thing also called PCX-T'). CPU frequencies were 100 and 120
MHz respectively IIRC, and the CEC (core electronics complex - busses,
memory controllers etc) were complete revamped (the 735/125 used
essentially the same CEC as the 720...) I believe that there was a
J210 and perhaps a J200 at the same time, the J being a two CPU,
tower, version of the C's.

CPU's to this point are all still 32 bit, PA 1.1 architecture. Core
network interfaces are all still 10 Mbit Ethernet (except the 735 which
could have a "core" FDDI interface).

The next batch of machines were a mix of PA1.1 and PA2.0 (64 bit
capable) CPU's. These were the B132L, the B160L and C160L (PA1.1,
PA7300LC CPU) and the C160 and C180 (PA-8000 CPU). The CPU frequency
was the same as the digits in the model name. Also introduced was the
J280 (Not sure when the J282 arrived). Core networking is still 10
Mbit Ethernet. The B's basically replace the 715's. (Yes, there was a
C160L with a 1.1 CPU, and a C160 with a 2.0 CPU. Have to be rather
careful with the names :)

The next batch included the B132L+, the B180L, the C200 and the
C240. These were CPU frequency boosts and/or a shift to core 10/100
interfaces. The B's are still PA-7300LC's, the C200 and C240 are
PA-8200's. A J2240, two CPU 240-MHz PA-8200 system is also introduced.

[ By now, the 8XX space is almost completely exhausted. I'm pretty
sure that the 7XX space was getting rather tight. Some numbers might
be reused, but I'm not certain. Fortunately software really only
need to know if something is a 700 or an 800, and even then many
things are merging - HP-UX 11 will have a completely unified kernel.

After that, the C360 is introduced. This is the first system to ship
with the PA-8500 CPU (again, a PA 2.0, 64 bit capable
architecture). The CPU frequency is actually (IIRC) 367 MHz or

Most recently, the B1000, C3000 and J5000 are introduced. These all
have PA-8500 CPU's. The B's and C's are UP with certain frequencies,
I'm not sure what. the J is a two-CPU system running at 440 MHz.

I'm sure I've goofed some of the relative ordering - probably with
things like the 712/100 and the 715/100 and perhaps the 735/99.

these opinions are mine, all mine; HP might not want them anyway... :)
