I like the dual carrier you have, it allows to have two LCDs on the same frame … umm is it a custom frame or a commercial one ? I'd like to pick up one.

From the price list I have seen around, I am afraid the price will be ~250..300USD, without the TRAM :shock: :shock: :shock: :shock:

so kind, thank you =)
hey oh? Swimming pool & Racing bicycle.
have you already tried to threaten it ?

something like - dear HP715, you should stop expecting from me to be patient about things you believe I will not put in practice if you do not obey my orders, so you have two choices: or you choose to put the damn console on the damn serial port, or you will be have a " full-immersion " about your duties -

sometimes, it works :D

I have bought a MaxImpact for a friend who is not familiar with ebay/dealears/forums but good at OpenGL programming, so I contacted a dealer in USA and I had a discount: 90 days of warranty included, we payed 300 USD shipped plus the 22% of fee to import, which is, from my point of view, too much money! I mean I think Octane is a better and cheaper system, especially considering I have for sale an Odyssey V6 GFX , asked 50 euro, and V6 against MaxImpact , comparing gfx about the perfromance/cost ratio, the Odysseay wins, it's staggeringly { faster, most featured, cheaper } by several orders of magnitude different.

in my head, the idea I have, is something like the following

  • 100000000000000 points / 250 euro asked for a V12
  • 1000000 points / 50 euro asked for a Odyssey V6 <--------- it looks the best Trade-off
  • 1000 points / 250 euro asked for a MaxImpact
  • 250 points / 20 euro asked for a SolidImpact

let me understand, is it GNAT ? if not, how have you integrated the ADA core inside the gcc tree ?

I need GNAT for mips32/BE, but I do not have a bootstrapped so I am blocked, while I have already completed on PowerPC.

Which applications :shock: :shock: :shock: ?

I know the real problem is with LCDs, I mean V6 needs more care about choosing the compliant LCD, I haven't experimented other troubles with any of these applications[]={ Mathematica, Illustrator, Photoshop, WordPerfect, MIPS/Pro, Premiere }, mainly I was using MIPS/Pro + OpenGL + gcc to develop something cool, but in my signature you can see what is in my wish list :D

( Ansys, Catia, Pro/E, FiberSIM, AutoDYNþ )

Well done! I bought an old MGRAS_SE gfx to develop around X11 with linux, but I still have to use seriously.

Vladio wrote: I noticed a lot of ebay sellers don't ship to Italy...why is that?


I still have to understand, overseas sellers have different opinions about europe and italy, sometimes it happens that parcel go lost, and in their minds "sometimes" becomes "too often", so they want to avoid to have troubles

the forget there is a solution for that problem, two solutions available
  • use the ebay-shipping program, if you agree, a guy will pick up the parcel at your address, and then they will apply the fee, and then the parcel will be in its way, handled by USPS airmail and, once delivered in italy), by SDS van, so you will receive it safely with the full tracking (and in case the parcel is lost ... there is an assurance with the full refund)
  • use USPS/Fedex by yourself, which seems more expensive then the ebay-shipping program because executives guys on ebay get discounts as they ship a lot of things

I have already bought a VPN accelerator card and a router from USA, the seller did agree to the ebay-shipping program, so I paid the import-fee in advance, ebay prepared the full shipping documentation, both the USPS and the SDA carriers did they job properly, and as result I had no trouble, and a fast delivery of just 1 week to get the parcel

dust bunnies, buddy ? were there no dust bunnies until computers arrived! ? Oh, does it sound like Alice in the dust land, like follow the dust bunny, and then tumbling down the dust hole. I wonder if there is a wonderland over there, the why on the why on the mystery of the why the dust exists, it might hide incredible secrets that your computers don't want let you know :shock: :shock: :shock: :shock: :shock:

vishnu wrote: I wish I had one room big enough for all my computers, currently they're spread over three rooms and they're all dominated by dust bunnies. :shock:


the logical consequence might be: try to reduce your computers to the number you can really care, or simply to the number of dust bunnies you can catch :D

I had this problem, and I took that decision: cary just one IP30, plus Cerberus and a RiscPC, I do not want to see other machines around, and no machines I can lift (under 40Kg)

p.s. the attic (where the IP30 lives) has less dust bunnies, than the living room, there should be a scientific reason for that :shock: :shock: :shock: :shock:
hey oh? Swimming pool & Racing bicycle.
understood

the attic has
  • no plants
  • no cats
  • no dogs
  • no human beings
so, no bunnies dust exist there

logical consequence: put all your machines in the attic :D

off course possible but it costs human resources, the time is one of them. Developing things in fpga takes time to debug them, a lot of time, and the hardware takes more times and money.

e.g. we (a friend of mine and I) have been developing a MIPS3 softcore for 4 years, it is working, but ... it needs more effort to be "validated". I can, in the theory, synthesize the whole MIPS cpu, adding an FPU, adding peripherals, and then I might build a "system on chip" able to run "nuttx" (similar to linux but real time OS), or I can quote the OpenMIPS project and their new RISC ecosystem, but ... that RISC soft core can obtain some 150 MIPS in a Cyclone V FPGA, while the SoC version (hard CPU core, ASIC) achieves some 4000 MIPS. That's a pretty good FPGA vs. ASIC speed illustration. It makes sense when you have custom tasks, and a customer that refunds your effort.

Hobby is completely different, and practically .... it requires organization, motivation, specialization, e.g. someone has to do testbench and it's a boring activity, nobody wants for her/his hobby


cybercow wrote: The other way would be possibly to translate GIO64 to something else


possible, but difficult, e.g. the RiscPC has a simpler bus than GIO32 (indy) and GIO64 (indigo2), it has a cheap connector, better signal integrity constraints (also because slower), but it required a lot of effort (and money) in order to interface the AGP bus. The final kit is still listed at 300 euro (with a 32Mbyte AGP card, only a few models are supported, and they must be flashed), just to plug-in a 30 euro AGP card. PCBs are expensive when the request is not in term of thousand of units, and on the software side it was difficult too, and we have sources about RiscOS (OpenRiscOS, v5/v6), while Irix is closed, it means reversing, which implies more effort, more motivation, …

uunix wrote: and probably stuff you could get on a PI


In an imaginary " celebrity deathmatch " in computer science, computer against computer, Risc PC/700 against Raspberry PI
they both run RiscOS , but the PI wins 1:10, it's 10 times faster, and it costs 1:10 :lol:

but … the PI misses the voodoo inside the Gemini chip inside the Guest PC Card
so, the fastDOSbox (~dosBox) can't compete with the magic of " !PC/Pro " :D

do you think it's possible and reasonable to redesign the heat sink ( MaxImpact Tram option) with a modern CAD/CAM process, then to provide it as "kit" or provide the full service (something like … you send me your MaxImpact card, I will replace the heat sink for you, you pay the kit and the effort) ?

I am thinking about companies like Daystar (USA), sometimes it's " Vaporware " like the news - Daystar Turbo 060 - sometimes it's the Truth. I do not know about Apple/68k, but know they offered something similar for Apple: PowerPC CPU upgrade, BGA package desoldering, chip swapping, and re soldering (with a few hack, off course, e.g. the PLL, and the Vcore), and with new heat sink design , mainly because the new CPU might need a stronger heat sink (e.g. from PPC750, 6Watt to PPC7410,12Watt). Sometimes they offer a completely brand new design, e.g. the SMP CPU kit 2x7450@2Ghz (designed from the scratch) for the Mirrored Doors PowerMAC (dual G4 1.6Ghz, the last one G4 machine before G5), but … that kid was extremely expensive (and more expensive than the cpu-swap kit) because they didn't make hundred thousand units, just thousand.

Contacting them, and buying a few CPUs from them, I did something similar (I have created a topic, just to post a few photos and comments) … the result is fine, not excellent because limited by the poor technology we used for the heat sink: we didn't use super heat-pipes (every modern laptop uses them), we just redesigned the previous heatsink and switched from aluminum to copper, and adding more copper and more "exchange surface". We didn't get the thermal resistance reduced by the magnitude that a super heat-pipe can offer, so it's not efficient, but it works!

The point I want to ask: today should be easier and cheaper, because there are more CNC and know/how: what do you think?

"handicraft", no cost analysis, no industrial process analysis, just do something cool, just do it, ten years ago I wanted to put my hands on G4 but I had no money to buy one, so I tried to hack my second hand PowerBook G3. It was in 2005, gentoo/PPC was a young child. I had a teacher in my university that helped me a lot with the design and thermal simulations, he was extremely good in CAD, and the CAM process was free because done inside the campus: we used the equipment of a laboratory in our free time.

Definitely not brilliant, the result is fine, no doubt limited by the poor technology we used for the heat sink: we didn't use super heat-pipes (every modern laptop uses them), we just redesigned the previous heatsink and switched from aluminum to copper, and adding more copper and more "exchange surface". We didn't get the thermal resistance reduced by the magnitude that a super heat-pipe can offer, so it's not efficient, but it works!
Please do not laugh too much (it's difficult, I know) about the little fan-cooler installed, It's funny, it's madness, but I can assure it's useful. Oh, and note the power on button, it has been installed under the little white apple in the top center of the screen border, you just need to touch it to switch the machine on.

that /etc/motd - Message Of The Day - file comes from what I have found inside a NetBSD hard drive
they gave me at the C.C.C. event ( C.C.C. stands for Computer Chaos Camp , it's an hack-camping event in Germany)

let me show you the evolution: Minerva is the next step!
  • completed in 2009
  • improved head sink
  • the fan cooler has been removed
  • holes on the bottom and on the top
  • a big heat sink grid has been built with aluminum and installed on under the top plastic
  • it's still laptop-shape, while Alice was converted into tablet-shape

Minerva is a PowerBook G3-PPC750@400Mhz, converted into G4-PPC7410@500Mhz (it's unstable >=@550Mhz)
it runs gentoo with a pretty and useful stage4 (with Xorg/x11 nanoX-profiled)

that's all, folks :D

tekterm, someone has mooed somewhere in the attic


It may be that I am too X11 addicted , but I guess the best practice to silence your gear is to put it in the upstair room and sit to an Xterm console . An xterm has no noisy hardrive , no noisy PSU , while it supports PS/2 kb & mouse, headphone and microphone, XDM, and it can have a very fast lan. My best experience is with Tektronix Xterm , I am very happy with it, the only defects are the pseudo-color support and the 10Mbit/s lan, I have found the cheapest model, but a pro model exists and adds 100Mbit/s and true-color. I hope to find, sooner, or later :D

of course, there is always a price to pay, " The end justifies the means " (cit. Machiavelli ), and the point is: you still see (the console) while you will anymore hear :D

Instead of having troubles with fan/disassembly/reassembly in order to replace older fan with modern fan (which potentially means being looking for more troubles if the Indigo2 is equipped with the MaxImpact gfx, also known as lord "heat maker" ), you can ease your troubles and enjoy the double with " Tektronix/Xterms " which have written, in their manuals, " compatible with SunOS and Irix " (they do not tell lies, their XDM is really really excellent, except (1)), and it should mean that they ( Tektronix dudes) sold their xterm as "solution" for who needs to have a console for bigger systems (Onyx2 ?), so it's not a modern approach to a vintage system, the Xterm has the same ages of the Indigo2, and was sold in the same years.

oh, well it seems I am attempting to get my degree in law in order to find a job like devil's lawyer (emm, and about that … I guess I have put the wrong English CD on, it's not " learn/improve your English ", that CD is talking about Machiavelli and Perry Mason :shock: :shock: :shock: so I decline every responsibility for the above content, it's that CD fault ), while I have written the above for those guys who are afraid to replace their fan-coolers (especially if they need stronger air flow because their GIO64 slot has met lord "heat maker" ), or for those simply want a simple alternative solution.

my 50 cents :D


(1) you also have to consider the other side of the coin
  • OpenGL is partially supported, cheaper Xterms may do not support it at all, e.g. my XP217 has no support for that
  • IRIS GL is not supported
  • Advanced Xterms have multimedia support (headphone, line-in, microphone, stereo)

is there a grammar mistake in the MOTD?

is it " welcome to Hell " (without "the") ?

I see " Welcome to the Jungle " (Guns & Roses song), " Welcome to Hell " (Spawn Comics)
funny grammar, like " happYness " vs " happIness " (used in "The Pursuit Of Happyness", Gabriele Muccino & Will Smith movie)

well, linux has a few troubles with X11 in order to support an XDM session which has to be compliant with Irix (especially with modern version of Xorg/X11 ). Of Course You can, no doubt about that, but you have to work hard to achieve the purpose, and you might be required to hack some lines in X11, while a tekXterm is ready out of the box fully compliant with Irix. Personally I do not like to hack things like X11 .

Personally I like Irix as software , and I like it because it's not linux, and I like SGI/MIPS as hardware , and I like it because it's not a PC, I have interest to study and hack the hardware, but I do not want to have the physical computer near me because it makes to much noises, and because I do not like to provide too many explanations about " what the the frog " I am doing. Also I'd like to be able to switch-on and then to access the hardware, from my smartphone , when I am out.

So this hack makes sense: sit in front of your tekxterm (when you want to access the full desktop, I mean when an ssh console is not enough), access the PSU_controller (1), tell it to swith-on the Octane , wait until the machine has booted, and enjoy (without any noise).

does it make sense ? oh man, yes, here it does :D

I'd like to know the reason why the IP28's PSU is warm (not hot but warm) when you forget to unplug the power cord while the machine is off: it means there is flowing current somewhere, that is also the reason why you'd better unplug the power cord once the machine is switched off.

In the PC world, every ATX psu has a circuit that always provides 5V@100mA to the motherboard, the real reason of this was just to feed a circuit that continuously monitors the LAN, listening for "wakeup on lan" packets, and in case of such an event, the circuit does switch electricity to the second stage of psu, so the machine turns on.

All the ATX power supply units do not really switch off like AT, and a 100 mA current flows through them, while all the AT units are really switched off, and no current flows through them.

Good theory, confirmed by the practice experience: I agree with the following!

Every electronic component eventually dies, but the expected lifetime for electrolytic capacitors is quite a bit shorter than most parts you'll find in the average computer. Unfortunatley, these capacitors play a vital role in the functioning of the powersupply of your computer.


mean time between replacements, MTBF, everything can be expressed by a Weibull Distribution , very useful tools come when probability theory and statistics are applied to electronics, topics like … using WD "to evolutes" reliability systems, charming math!

Electrolytic capacitors rely on the surface area created between an etched metal electrode and a liquid electrolyte (which forms the other electrode) to function. Unfortunatley, this liquid electrolyte has a nasty habit of evaporating over time, which can range anywhere from 25+ years for a very large/cool capacitor to 5 or fewer years for a small/hot cap.


sadly the Truth with old technology, especially about electrolytic capacitors: I got very bad experiences with IBM S/36, I mean I found a lot of dead electrolytic capacitors, so the 99% of the fault was related just to them.




fingers crossed
good luck =)

Man & Machine

In the beginning was man, and man wanted to know, and so man learned, and the Universe was thus deciphered, or plausible substitutes for the indecipherable presented. And when man mastered " the physical " he looked to his own soul and saw it could not be explained quite so easily. How did a vast collage of atoms and molecules develop a consciousness and intelligence? Here, now,was the challenge to rival all others, here was a chance to become God and to make others in man's own image. But how?

interesting :D

here I have to play with PCI 5v @33Mhz on an Atlas board for job purposes, firmware fun, but I am planning to attach a pci-fpga board, and when I will be skilled enough It may be I will think about the Shoehorn in order to provide a few new peripherals to Octane :D

@cybercow
what @miod has pointed out is the reason why I was talking about fpga: custom bus needs custom design :D

p.s.
it's not SGI, but about having fun with HW (without the complexity of SGI), this seems a good wicked plan

Lady Death is a fictional wicked woman, appearing in American comic books published by Eternity Comics . Created by Brian Pulido and Steven Hughes , Lady Death first appeared in Evil Ernie #1 in December 1991, while Lady Demon came about when Lady Death realizes she is a mistress of puppet , and all her life in hell is all a plan by Lucifer. So bored, and frustrated, the journey of self realization was so traumatic that her demonic person came to a life of its own. So Lady Death became Lady Demon , and true wicked blood stories came.

There is an episode, Lady Demon was looking for a body to inhabit, otherwise she would be pulled back to Hell. She found one woman who has killed her husband and then herself. This body suits Lady Demon better than the last one. So hidden inside a human body, she became a free witch. The body to inhabit belonged to a she-lawyer.

Does Lady Death really exist? Did she really exist? Let's ask the Science about!

Image
Lyudmila Pavlichenko was called " LadyDeath "

For all the devils of the Hell, the Science has found a match , even if I believe there is a misunderstanding, she is not THE " Lady Death " whose story is a good way to learn English, that's an other story which reaches a more violent and bloody peak during the World War , a true horrors being wrought upon everything, including their own life, the freedom, the honor, everything may be lost forever.

Ukraine's Crimea peninsula during World War Two , battle for Sevastopol in May 1942. A key port city on the Black Sea, came under attack from five Nazis divisions, supported by Luftwaffe bombardments. Lyudmila Pavlichenko was sent to the frontline in 1941 at the age of 25 after being trained as a sniper, and she is said to have killed no fewer than 309 Nazis during the siege of Odessa and later the strategic city of Sevastopol on Ukraine's Crimean peninsula .

The close up shot of newspaper section politics got shot at title " Lady Death: the nazi killer who become guest of U.S. president "

So we have a proof, the science has demostrated that Lady Death, actually existed , but what about Hell ? The science is now wondering the reason why also Hell exists, because a proof of the Hell existence is the following

Code: Select all

void reset()
{
void *jump[] = { halt, soft_reset };

/*
* what the frog is this ? assembly branch?
*   looking at the asm level
*   it is translated into "bra address"
*   which is an uncodnditional branch
*   it's not a function call
* so what about the stack?
* no doubt it gets compromised
* does it make sense? so why they allow this crap?
* oh, just to invoke the soft_reset
* so it really makes sense
*/
goto *jump[1];
}


Code: Select all

void soft_reset()
{
/*
* hAllo, buddy
* the stack is now compromised, completely gone
* but don't worry I am the machine reset
* see you later, reset is coming ^_^
*/

die(); /* Just kidding! Say hAllo to lucifer, you are going to pass through Hell */
}


and .. it's not a comics, sadly the Truth ... GCC implements the "goto" and the above wicked code is perfectly compiled without a warning, the demonic person of gcc came to a life of its own, gcc came to a life of its own, Hell in town, Hell in console, Gcc is looking for a body to inhabit and if you try to execute the above code on a bareboard machine (without an OS that can handle memory protection), you will see how deep Hell's throat goes. May you save your *** from the suicide rabbit.

Image
never follow the suicide rabbit down into Hell's hole

corollary : GNU guys are really wicked , more maleficient than Lucifer (even if their girls are less sexy than Lady Death , of course, except girls in BSD, which are really sexy witches), I suspect that only devils hidden inside a human body could think such a maleficent.

Image
never follow the suicide rabbit down into Hell's hole, even if you are tempted to escape away from Gcc

my humor, I am upset by the code I've seen: can I pay now someone to cut mr Stallman 's beard ?
Can I offer him a copy of Lady Death as motivation to remove the above wicked-goto-feature from GCC?
I wish I could enter into the vegetable garden of William Gibson , on the right of a director, to decide how a film is ultimately released for public viewing, but I am not a nor Cyberpunk writer neither a dude in Hollywood , and my * flawless English * still looks like an old rusty trailer which needs a fix-up, so my personal wonderland begins with a pill ... tumbling down the rabbit hole , where the sky above the router port is the color of television, tuned to a dead channel and some gears still need a debugger there.
yes, SierraC can't do that, while gcc can, so it really seems specific to gcc, which might break the portability, increase the entropy, and I can't find NO reason for that: it should be banned and removed!

p.s.
I have found " goto " inside the source code of VxWorks v5 , linux , and Integrity , I am a bit shocked to see that (" goto " has been banned by Misra ), even if none of them used the wicked tricked above , whick allows you to jump from a function into an other , with a so dangerous conseguence for the stack that crashing down the machine has a very high probability of disaster.

see the wicked example above, "goto" is always implemented with an " unconditional branch " (often called "bra") which "jumps". It means, the "program counter" (cpu.register.pc) is reloaded with a new value, and this value is the address of the next instruction to be executed, there is no stack manipulation (stack push, pop, sp--, sp++, nothing of these), so .... if you jump within a function there is no problem, no trouble, because the stack is not compromised.

Using "labels" is an admission of guilt , you have failed to design your code in the properly way , it will never pass the MISRA check which bans every goto, but formally it's a valid code without hazard.

Code: Select all

void *jump[] = { halt, soft_reset };
...
goto *jump[1]; /* it's not a label, it's an explicit address, which points outside the function you currently are in */


But what happens if you attempt to jump outside the function you are in? It happens that the stack is smashed, invalidated, gone, garbage!

It's insane! SierraC refuses to compile every "goto *xxxx" simply because it's dangerous, while gcc implements an extra feature that enables you to jump outside the function you are in, jumping directly into an other function but without closing the stack, and without preparing the stack of where you are going: the result is a catastrophic hot jam, a situation in where you have completely lost the return address, the frame, and all the local variables !

edit:
a few weeks ago, I opened a discussion here , about the C language, It might be interesting.

robespierre wrote: Gotos to other functions happen naturally once you have first-class functions


first-class functions , but

bra is different from jsr , and the machine layer of a C compiler implements differently
  • goto *xxxx -> bra -> no care about stack -> the invoked function can NOT return, and can NOT use local variables, foot shot
  • function call -> jsr -> care about stack, return address, local variables, frame, everything allocated in the properly way

as far as the " freedom ", if you really need to " jump " into an other function, do it in assembly -> which means explicitly defining and using an " unsafe piece of code " as it's called by ADA.

interesting

find that developers use goto in C files for error handling
and cleaning up resources at the end of a procedure




btw, this topic is LOL collections of motivation to prove that Hell actually exists :lol:
