it would be nice to have it on Irix.

The whole HP Visualize series was designed for the toughest work in the technical computing, and with rock-solid 64bit HP-UX v11 operating system it rises to the extreme challenges of electronic design, including system-on-a-chip simulation and IC verification. Good. Designed for the toughest work. On which software ? Proprietary ? OpenSource ? Is it avaiable for Linux-HPPA2 ? No gnat available for HPPA2, so no ghdl, so no system-on-a-chip simulation and IC verification. So you need to pay for a proprietary software for HP-UX v11. Which is RIP, nowadays.

Don't you know someone with a gnat-bootstrap for freeBSD, Linux, opensource whatever? It's a pity we have powerful and stable machines, without gnat. And i am lost without ghdl (whose primary dependency is gnat) because I can't simulate anything ='(

to compile ghdl ? will it work? who knows
it would be fab.

p.s.
do you have PA-RISC or Itanium cpus on your C8K?
I don't see FreeBSD in the openpa page
Supported OS. It says { HP-UX, Linux }

I wonder why. It's so irrational

R-ten-K wrote: Linux in HP-PA works fine as long as you keep yourself to one PA-8800 or PA-8900 chips in your C8000. Apparently, there are no developers with access to multichip C8000s or PA Superdomes, so the main issue with Linux in this architecture is that the algorithm for SMP coherency is rather "brute force" and since the latest PAs had very large L2s (32MB and 64MB respectively) things like cache flushes can induce some serious overhead.

so, Linux is not good on a dual CPU. Also, 64bit kernels seem to have troubles.

can someone report some good benchmark ?
also, soneone on linux with those machines ?
I see no applications for HPUX.

gEDA would be very useful on Irix!

That's interesting! Which Power8 ATX board ? Where can you get it?

I believe the best PowerPC 32bit ever made is the PowerMac G4 MDD dual 1.4Ghz!

It comes with four PCI slots at 64bit, and processors can be upgraded with the last super-rare Sonnet dual-cpu kit.
Elegant, powerful, I believe there is no other G4 tower in these conditions around the world!

Linux works great there!

Nah, it's fast for my needs! gEDA doesn't need more than 700MB of ram. So 2GB is fine!

guardian452 wrote: 2010 was a long time ago in the computer industry. Those machines are twice as old now.

Well, sadly the Truth: for a lot of C++ applications and C++ library (e.g. QT) needs more than 2GB or ram and modern simulators eats more than 3GB of ram. So you'd better have 64bit kernel and userland, and more than 4GB or ram installed in your system.

PowerMac-G4 are doomed since they are limited to 2GB. Correct!

Fortunately I don't need to develop on C++, but I happen to use those simulators, and I have recently installed 8GB of ram on my C3600 because I need 6GB of ram disk. I am using opensource-EDA and its simulators on linux-hppa and they all run 400% faster in this way.

In the theory I could buy a sATA-RAM-DISK but it's very expensive: 32GB costs 500 euro + VAT + postage.

It's the main and only reason why I have put 130 euro in 8GB of ram and also the reason why I have moved from 32bit-kernel to 64bit-kernel, but I am still with 32bit userland. No reasons to move, especially on an experimental architecture.

I bought a XEON M3 machine for my job staff. It's also perfect for commercial EDA (OrCad, Altium, etc), even OrCAD requires x86 and Windows. Unfortunately I am still with a mixed set of 32bit and 64bit applications. Some of them requires XP/32bit, so … I am obliged to have a virtualizer, and WMPlayer is perfect for my needs.

Say -600 euro for a Fuel- is a reasonable amount of money to start having a dig through this box. You might love it or find it boring and useless. It's all up to you.

A Fuel doesn't cost you an eye and a leg (British idiom for 'a lot of money'), therefore the question is: if you happened to have put 3K Euro (or more money), then for what do you used your Tezro? The sentence sounds this way because a lot of people has answered "dunno, still unused on my desktop"

In UK there is a wonderful place called 'Portobello Road'. The world’s largest antiques market with over one thousand dealers selling every kind of antique and collectible!!! And visitors flock from all over the world to discover one of London’s best loved landmarks which contains the most extensive selection of antiques in Britain. Last time I was there, I put my finger in the direction of an old oil lamp and then I asked - how many Quid (pound sterling) for this ? - And the answer was - it costs an eye from your face, chap -

I don't get your logical. Why are you collecting so many octane-units? Are you going to build a cluster? Willing to offer a rendering farm service dedicated for Maya? so you make your rendering x hundred times faster?

What's your hidden secret plan?

I need more space, I need to connect two internal hard drives. My HPPA workstation is SCSI UW/DIFF. Since a brand new 150GB SCSI hard drive is listed at 150 euro, whereas a SATA 1TB hard drive is listed at 50 euro, and I need 300GB of space, I am moving to SATA. Fortunately I don't need HPUX, linux is fine, so I have just to find the right controller.

What do you think about Marvell 88SX6081?
It should be < 3Gbps, PCI-X 64-bit @ 66MHz
but I believe ~ 100MB/s on each SATA port.

interesting

kernel v4.9.* seems to have interesting sATA stuff under SCSI's kconfig (does it make sense?)
e.g. drivers/scsi/Makefile:obj-$(CONFIG_BLK_DEV_3W_XXXX_RAID) += 3w-xxxx
which points me to 3Ware 's stuff

3Ware cards are usually well supported on Linux.
Theses cards are often considered as some of the bests hardware RAID controllers for GNU/Linux or BSD systems.
3Ware supports Linux and provide an opensource kernel driver which has been part of Linux for ages

2. Linux kernel drivers
There are two drivers for 3ware cards:

Driver Supported cards
3w_xxxx 3Ware Eskalad 7000 and 8000 series
3w_9xxx 3Ware Eskaled 9000 series

You should not expect any problems with theses drivers which are known to be mature and stable.
We don't know any current Linux distribution which miss theses drivers so no additional step should be required to get it working.

Does someone confirm it? On Kernels v4.9.* as well ?

These cards exist in PCI-X @ 66Mhz, around ~50 euro , acceptable for me, but I want to be sure it's a good choice.

I am tempted by 3Ware Escalade 8506-4LP

mattst88 wrote: The SATA_SIL card I recommended had no such problem

Perfect for my HPPA workstation, going to buy a couple of SIL

But let me understand about 3Ware. I don't need to setup raid, I mean in that case it will be soft-raid (done by Kernel).
Can 3Ware be used as "simple" sata interface? What I really need is a fast interface.

I don't get how the machine-interface (IBM calls it "MI") works. They say the AS/400 is somewhat unusual because there are two machine-levels that play a role in practice. The upper one is called the MI-level and the lower one is the CISC/RISC platform, therefore MI, the Machine Interface, is in a very real sense what makes your machine an AS/400 rather than just a souped-up PowerPC. AS/400 is made in layers, and the operating system does not depend on the lowest layer (the hardware), therefore you can change processors (e.g. from CISC to Power) without the need of touching OS/400, and applications (the highest layer) are also independent.

How is it possible? Doesn't it sound like "java"? And exactly, what is the Machine-Level? And what is above and below the MI?

So, is it similar to byte-code?

How have you made labels? I wonder why don't (if it's possible) put a micro drive (through a USB-CF adapter) inside the case. Can I see the inside? Is there a mechanical drawing sheet?

Nice project

Yup. The same here with OrCad and Tina.
I don't care if the underlying OS is Windows.

Who did manufacture the best X window system terminal ever in 90s?

Weren't 68Ks (020? 030? 040?) a bit slow ? Never seen any 88K model, what does it run? VxWorks?


HP Envizex, here it is a video, it shows a unit booting up (ENWARE X-station software. Release 7.0, maybe)
What about HP-Agilent Entria? Any feedback? I know they exist, never seen/tried one.

p.s. the brochure says HP ENVIZEX "p" series and ENTRIA"Plus" users who purchase an optional MPEG accelerator card can now view full-speed MPEG videos with synchronized CD-quality audio.

Interesting. Network Computing Devices was a company founded in 1987 in Mountain View, CA, and when it closed it was headquartered in Beaverton, Oregon. At some point NCD purchased PCXware, which made an X Window System for Microsoft Windows, and the TekXPress X-terminals line from Tektronix. NCD ceased operations in 2004, but a few of the company's employees have set up a new company, ThinPATH Systems, to provide former NCD customers and others with service, support and products.

kjaer wrote: What is it you think they needed to be "fast" to do, exactly?

By judging *how slow* is X11 on A/UX 68K, and comparing the behavior of an xp217c (tektronix/tekxware v7), which has a MIPS3 @ 20Mhz, with an xp417c(tektronix/tekxware v8.1), which has a MIPS3 @ 40Mhz, there are so many differences in 20Mhz that you feel more comfortable on xp400s, especially if you want to have a native Netscape browser with Java v1 (you need NCBridge)

kjaer wrote: 1-bit X server

XPs are pseudo color.
They do a lot of tcp/ip connections.

kramlq wrote: M88k

Never seen one. According to its manuals it's a superscalar RISC. I assume it's faster than 68k. But I wonder how comfortable was the software if there wasn't WxWorks (not existing for 88k, right?) under the hood.

kramlq wrote: We'd have loved XTerms to stay using slower M68k rather than the newer 133MHz MIPS R4300i

Why? For the software? Talking about HP products, the old Enware v7.1 supports i960-based terminals, including the HP Envizex pSERIES, which was the top gun, with the fastest CPU available and maximized ram. The next step of HP software was Netstation Version 8, supporting MIPSR4300-based terminals.

Talking about CPUs, no doubts MIPS R4300s are faster than i960s, but Enware v7.1 is more comfortable than Netstation Version 8, more optimized, it eats less ram, and it adds less whistles and bells (e.g. HPUX CDE-like objects)

kramlq wrote: the company I was working for was Motorola

Have you ever seen IDP products? I read a brochure by Motorola and Motorola DNA, it talks about a development board with expansion cards. One of these cards is a video display unit, basically an interface to VGA, PS/2 mouse and keyboard. A second card is a 10MBit/sec lan adapter. The rom is composed by two UV-ROM of 512Kbyte each. The total memory was expandable up to 8MByte on the motherboard, plus other 16MByte on a dedicated memory-expansion card. And the built-in firmware (like in ColdFire-v1..v2 boards by Axiom) was able to tftpboot.

So, I wonder ... have ever been used for prototyping Xterminals?

Shiunbird wrote: I guarantee you will get a fantastic job in the future

Bah, I am afraid nowadays all the knowledge acquired on how to reinstall windows doesn't pay you back, especially if your salary is three times expensive than employing three Chinese guys for the same amount of money. They have also mastered how to reinstall Windows (and also Linux, LOL), and they are more efficiently and cheap than you. Today you are requested to do more advanced stuff, and it happens that almost the most part of the serious part of engineering is made abroad, imported, so again and you won't be paid of it (thanks to China, again).

Life has become complex. Especially life on computers. Therefore a fantastic job should be searched in the field of food, since you can stay without a computer, but everybody must eat!

Knowing how to prepare delicious dishes, and ice-creams, can't be overridden by the so called "Chinese's art of being masters at copying for replicating and releasing cheaper".

Sure, everyone needs a hobby. Sometime a hobby can make you more strange.

My next-door believes she can have an artist profile feature, so she’s now following the surrealist painter and sculptor H.R. Giger, the one who created all the alien creatures we can see in Ridley Scott’s sci-fi/horror classic Alien.

I don't know why she loves H.R. Giger’s style, for me it's one of nightmarish and surreal landscapes and figures which some have described as Satanic, perverse and disturbing.

She has changed, her hobby has changed her style, converting her flower-power picturing style (at the beginning she was attracted by flowers, like an hippie) into something in where she emulates Giger in combining biological anatomy with the mechanical to create works of art that have become favorite of certain death metal, and she is now experimenting strange airbrushing techniques to create monochromatic pieces she has, of late, switched over to using pastels, markers and inks.

Last time I said "disgusting", she replied “ all the beauty lies in the eyes of the beholder. And that's my hobby, in first place ".

Sure, her terrifying hobby.

We go in circle.

Modern computers are boring and less interesting, but they have power and software, which makes them more interesting for practical purposes, e.g. if you have to design your own PCB and build your own HOME made electronics.

Old computers doesn't have enough power, and when they have enough (e.g. Octane2, Tezro, Onyx2) ... they don't have software and they cost a lot of money (e.g. a Tezro is $2000 at least)

Even for my hobbies, I need OrCAD, I need Altium, I need SolidWorks, I need ISE (to play with fpgas). I can run none of them (and there isn't alternatives for IRIX) on any SGIs.
