here I have only these machines

• Cerberus , which serves the whole local infranet, exporting NFS (Irix and linux filesharing), SMB/CIFS (Windows filesharing), SSHFS (RS/P, over FUSE), HTTP (personal wikipedia, personal blog), and RAID mirroring on a pool of 3 pairs of hard drives. It's located in the living room, it does makes no noise, it has a 7" LCD with touch screen on the front, and it's easy to control, so my girl friend is happy with its wikipedia and blog full of fashion things (OMG, I have reserved a pair of hard drive, a.k.a the whole pool0, to her needs)
• Octane2 , aka the big iron in blue hulk skin, currently does not wear any plastic and it lives hidden in the attic, attached to a control box with a lot of thin cables and wire going in and out its front-plane. I was said that it looks like a troll in its cyberpunk cave out from a Gibson's story (o'really ? )
• RiscPC/600 1 Slice, it lives in my little office standing vertically, looking for a second slice in order to hide an MC68332 inside, plus its equipment. I have hidden an embedded linux board inside with the purpose of providing a better file sharing (may be VNC) to RiscOS, which runs a true DOS box over gemini_II chip (486DX4@100Mhz). It's a very nice, quite, fast, and funny machine, especially if you install a DDE kit
• RS/P plus its external harddrive, it is so tiny and smaller than hulk by several order of magnitudes, that it can live in the living room, hidden under the hifi box, like a dwarf in its cave. It's MIPS32-R2, it shares a part (compiled as MIPS1) of its rootfs with Octane2 (MIPS4), oh well, but it worked only with kernel 2.6.17, cause kernel 4.1.* does not work with binaries compiled for PAGESIZE=4Kbyte, it wants PAGESIZE=64Kbyte. I am distilling a new stage, which does work
• XP217 Xterm , located in my little office, near RiscPC, no bigger than a toaster, it's tftp-bootstrapped by Cerberus, employed as console of everything, including Irix

my girl friend said
- chaos is not allowed, things must be in order!
- things here (especially things in the living room) must have a purpose

corollary: if she doesn't see, then it's ok
consequence: things must be hidden, like Transformers or dwarfs in their cave

so, can I use Lord Crimson as "wine refrigerator" ?

kubatyszko wrote: "stripped" not "striped"

I have written

I can make it "stripped"

which is the right form ? the verb is "to strip"
as examples my dictionary says

• a) "the lieutenant was stripped of his rank", with the meaning "to deprive someone of { rank, power, or property }"
• b) "her body was striped with bands of sunlight", with the meaning "to mark with stripes"

" to be stripped " (double "p") means to remove clothes(1), "clothes" in this case means extra-features, like what glib adds, a lot of features which makes binaries bloated. Symbols do also make them bloated, in this case applications do not need them, while shared libraries do need.

/usr/bin/strip can purge

(1) the funniest example ever, it looks like a survival English dictionary, the best purchase ever
it reports this practical sentence: "Is there a striptease bar in the town? where girls get stripped"

kubatyszko wrote: Stripping binaries (often via 'strip' command) or OS means removing all non-critical stuff, essentially making it lighter which is likely what you want to achieve...

I guess the meaning is clear, the purpose of "to strip" aims for reducing the data stream size over the lan because the IP22 comes with a built-in 10Mbit/sec NIC, which can be expanded up to 100Mbit/sec by G130 or G100 or TI gio32 boards, but the PROM (ROM firmware) comes with no drivers, so, you can use these Fast-Ethernet cards only once Irix (or Linux) has completed its boot: you'd better (and best) reduce the data transfer!

practically a bloated rootfs implies the usage of two network cables, the first connected to the built-in lan in order to tftpboot the kernel, the second cable connected to the Fast-Ethernet board in order to upload the rootfs at decent speed

the problem is: I can handle the above diskless setup with linux (the worst choice ever on these SGI machines, especially on IP22, it's too slow and X11 comes with a poor frame buffer which makes the machine slower and not comfortable with X11-stuff, I know, I know, but ...), I can (it means am able to) rebuild the whole stage4 (including X11) in uclibc way, which is smaller than glibc by different oder of magnitude, I am also able to tftpboot an IP22 width such a stage included in the kernel as ramdisk (and I might implement a custom earlyrootfs with a NFS client), while I do not know how to do something similar with IRIX

deadline respected by the end of the year:
completed 20 minutes ago
we have a working kernel v4 with a working uclib-rootfs
Yahhhhooooooo

+H~a~P~p~Y~n~E~w~Y~e~A~r+

" stripped " in order to reduce the data-transfer.

In this case, I wonder how much smart is to look for a striped -ram-rootfs with an MIPS3

I agree this is not simply a spelling error or typo

I don't really know why GaGa hates everything that looks like a blue-hulk, she was not showing so much anger against the Red-Fuel when a friend of mine parked his red-box on her living room, perhaps because she knew it was not permanent (it went out in a few days, I just needed to install him a full and fresh Irix 6.5.27), perhaps because the Fuel didn't make all the noise that Octane does, perhaps becuas Octane is blue while Fuel is Red, and she hates blue cause "I feel blue" means "I feel unhappy", who knows

Irix@XDM over XpressWare

smj wrote: archaic version of X

in my practical experiences Tektronix XpressWare v7 (the running firmware in my XP217) is perfect for my purposes
and it supports Irix over XDM.CP

XpressWare is smaller and lighter than NCBridge , even if this one has more bells and whistles (nothing really better in my opinion)
The Boot Monitor is a built-in command line utility that provides easy way to input boot commans.
When turned on, the XPterm obtains its IP address and other information via BOOTP, then load the software from the server using TFTP
while if stopped by a key pressed then the BOOT> prompt is displayed on the screen, waiting for commands.

The OS is a Wind River VxWorks v5.* real-time OS, and the file format is MIPS ECOFF/big-endian

Practically a very good dog, never had a trouble with a software which comes under the definition of "Open/Motif compliant"
my problem is just this: XP217 is 10Mbit/sec & pseudo-color, and … I'd like to have a 100Mbit/sec & full-color!

I mean, 8-bit visuals and palette-swapping, said pseudo-color, oner 10Mbit/sec is good for light remote terminal work, but!
but don't expect to be able to use graphics-intensive applications or watch video on them!

smj wrote: Something to be said for finding or making a stripped down Linux or *BSD image to run on them.

In this case I am able to build a stripped linux distro uclibc based with X11 included (1)
so the best choice comes with the use of a board like this
x86 compatible and low cost (brand new for 180 euro, second hand for 50-70 euro)

but (2) I am simply too bored about that

p.s.
a friend here has converted his old & obsolete Apple Book Air into a pretty X11-term
he just needed to install "XQuartz" (which comes free for a personal usage) on MacOSX v10.7.5.
I can confirm it works fine!



(1) already built for my job (x86), used by Cerberus (PPC), used in my RS/P (MIPS32)
adapted & rebuilt a few days ago for Octane2(MIPS4), and in 2007 I did something similar for HPPA2

all of the above is practically used as "net boot", usually for first-aid purpose
I mean it bootstraps from lan, then the core runs entirely in ram and boots very quickly
it's a good tool when you have to repair a filesystem, or when you want to fix/upgrade/backup stuff
currently it's text console based, I might add X11 nanoX profiled to the userland but (2)

I owned an LC475, hacked to be a 68060 gentoo/m68k machine
mac OS 7.5 did no longer power-on, due to the fact I re-programmed the 4 ROMs
because 68060 needs a special support pack in its early bootstrap

that machine was then swapped for a RiscPC/600 machine
that is more useful for my 332 development

A/UX on a good 68K machine is still on my wish list
still tempted even if it will probably never happen (it has no real purpose)

robespierre wrote: The O2000 and Onyx2 (and by extension the Octane and Tezro) are based on an academic computer design from Stanford called DASH. There are many papers about it on citeseer. This design uses directory memories to produce coherency from a loosely-coupled mesh of processing nodes (each of which has several CPUs in a traditional SMP arrangement).

Stanford DASH

Stanford DASH was a cache coherent multiprocessor developed in the late 1980s by a group led by Anoop Gupta, John L. Hennessy, Mark Horowitz, and Monica S. Lam at Stanford University. It was based on adding a pair of directory boards designed at Stanford to up to 16 SGI IRIS 4D Power Series machines and then cabling the systems in a mesh topology using a Stanford-modified version of the Torus Routing Chip. The boards designed at Stanford implemented a directory-based cache coherence protocol allowing Stanford DASH to support distributed shared memory for up to 64 processors. Stanford DASH was also notable for both supporting and helping to formalize weak memory consistency models, including release consistency. Because Stanford DASH was the first operational machine to include scalable cache coherence, it influenced subsequent computer science research as well as the commercially available SGI Origin 2000 . Stanford DASH is included in the 25th anniversary retrospective of selected papers from the International Symposium on Computer Architecture and several computer science books, has been simulated by the University of Edinburgh, and is used as a case study in contemporary computer science classes.

any good book & paper to learn about that ?

- 10/100 Ethernet { G130, G100, TI#9210110}
- second Narrow SCSI
and an upgrade ram kit, 256Mbyte

can someone confirm me that XP400 needs Tektronix XpressWare v8 ?
does somebody use it ? It seems that XpressWare v7 does not support XP400

I am a bit confused about XpressWare

XpressWare V8.0


it doesn't say which XP terminals it supports, while the following is what I have in my XpressWare V7.0 CD





I have a table which says what is supported

• os.010 -> { xp11, xp12, xp13, xp18, xp19 }
• os.330 -> { xp334, xp336, xp337, xp338 }
• os.350 -> { xp100, xp114c, xp115m, xp117c, xp119c, xp119m, xp217C , xp350, xp354, xp356, xp358 }

so, as described here , my xp217c requires os350, I can confirm it works good
but I have no idea, and no documentation about xp400


Pages like this do not help, while the Entropy is growing up X___X


googling I found an article, written in Spanish

... estos terminales requieren el software XpressWare v8.0 o versiones posteriores.

it says that these terminal require XpressWare v8.0 or above (which means v8.1, the last one, or NCDbridge)
so no chance with my XpressWare v7

I do not know, but I can say that the old rootfs is working fine with MIPS32r2, successfully used with kernel 2.6.39 and v3.* on my routers, so, I suspect the kernel v4.* is bugged somewhere as I can't run the last 2015 MIPS4- glibc -stage3 made by Catalyst with PAGESIZE={ 4K, 16K }, while it works fine with PAGESIZE=64K

Concerning XP400 && Xpressware v8 , it seems that computerequipmentwarehouse has it, but … they said that they are used to be reps for Tektronix and their deal with them was to sell the machines and load software rights on there, so they can't sell just the software , they can program authorizations for the softwares and make them talk to dec sun etc but they cannot sell the main system software they load them on.

in short Xpressware v8 + XP400 takes 598..698 USD

Yes : in Europe.Italy we have 240V
No : but my IP30 system is powered by a diesel generator (2), which comes with 120V setup
so I modified the IP30 PSU instead of buying a more expensive converter for the generator (1)
it's 5Kwatt diesel generator, paid 200 euro for the whole as second hand




btw, things within the range { 200, 300, 400 } Watt are greater than things within the range { 20, 30, 40 } watt
corollary: RSP & Cavium Octeon eat less electricity -> they are 10x better dogs !


(1) here the electricity costs a lot , so I applied a wicked trick to be minded about that
my power generator eats diesel as my car eats petrol, and my car does 16 Km with 1 liter of petrol
so, I have to be careful how far I am used to go, and how many times I am used to drive
and how many times, and how long, I am used to use the IP30

I happen have three of these strange MicroDrives, look at the picture, they don't come with a CF interface
so I do not really know how to interface them

Microdrives are used to have a CF interface (including its mechanical connector) and comes with a subset of pATA
don't you guess why I have posted here ? for a reason: someone might have already used or might have already found a solution (1)
or might have already tried to hack them (wiring out into a connector ?) or just might need them

(1) ebay does not have these ZIF adapters

the real problem is: what do you run on them ?

HC11 EVBU replica, RAM, NVRAM, expansion BUS, built in serial + second ACIA, ROM containing BUFALO & noICE11's stub

Olimex Arm kit, DMA, SDRAM, usb-host, DSP acceleration etc etc etc including an hardware debugger usb driven

I happen to come back to my university for a second degree
(I already have a degree in Computer Science, I can obtain a bachelor's degree in Electronics Engineering in 10 examinations,
as I already have a bonus from my last degree, don't ask my WHY, it's an hot jam caused by my university, already paid taxes)

so, properly sitting in front of the blackboard, I was asked " Which MCU would you choose if you could redesign Arduino today? "

oh Hell, in first place why on the why should I have to re-design Arduino?
Should I aim for getting Massimo Banzi kicked out of his lies business over open source(1) ?
oh Hell, what a wonderful wiched plan

I was dreaming about the the most evil plan ever against Banzi, when professor said " can I have your attenction, please ? "
"yes, off course, I was carefully thinking about the answer"
and as answer I showed him my pretty HC11 EVBU replica, claiming it's better than every Olimexduino ever
(including my marvelous voltage pump, home made, from 5V to +/- 12V, used to power the RS232 circuit
it's stored in the plastic cylinder you can see in the picture, it looks so profession that it needs to be closed with a tape )

and professor mr WasteMan asked "are you serious ?"
and I answered "yes, I am"
and mr W-Man said "so, go out!"
so I asked "with or without whistling ?"
and he screamed "Go Out, Nowwwwww!!!!"

and so I did, whistling better than Scorpions in Wind Of Change

the House where I live is property of my girlfriend, and even if I pay half the electricity she doesn't like the IP30, in first place

she understands Cerberus because she uses that machine for her personal photos album and mp3 playlist player
while doesn't understand the BlueQueen (aka IP30) because she sees a strange iron that has the only purpose to eats electricity
so the Queen must be hidden in the attic, and remotely controlled over the lan

she can't understand what goes through the lan, encrypted by openSSH, and she is not familiar with lan-sniffers
but if I use the house electricity to power the big iron then she catches me immediately !
due to an electronic main control I have installed in her house (d'oh ), she can check the electricity, room by room
so I'd better use a diesel power engine, which is outside the house, hidden in my garage, literally my personal Neverland

so, "the cause" sounds like Peter Pan vs She-Captain-Hook

even if, some days she makes herself called "Hook" as the wicked woman in Piracy ever

oh, also I have installed a few solar cells over the garage's roof
they recharge a big battery (still experimental), which comes also charged by the power generator

this equipment can't be hosted inside the house, and I can't stay in the garage
it's too cold over there (-7 C), so there is a big hidden power cable between the garage and the house
it comes to the attic (over a groove) and it feeds the IP30. That room is never less than +8 C, even if … there is too much dust

Kumba wrote: The power supply is auto-sensing and should handle either 120 or 240 just fine. And what did you modify on the PSU?

my Diesel Power generator comes with a very bad designed output stage, in first place it seems it has a too poor output filter
and as results its signal shape is not a sinusoidal wave, it has a lot of components at low-middle-high frequency spectrum
which is OK for an electric drill while it's very very bad if you want to power supply a computer equipment
(this, even if the switching stage inside the IP30 PSU comes already filtered)
so I added another strong filter in order to suppress them and the BlueQueen is feeling fine

if a machine like my RSP eats less than 50 watt then I can hide it from the electricity meter, so it's a "good dog"

about electricity, I measured a Seagate ST3146855LC , it's 147Gbyte, 15000 RPM

so, I can deduce that having 3 SCA hard drives in Octane means something like ~3x15=~ 45Watt

Never used a DAT before, never toughed a DAT cartridge, I wonder how much safe they are as backup-media if compared with hard drive, CD, DVD, and USB pen drive (for these one, IRIX needs to pass through a PC over NFS, as IRIX does not support USB-BULK in her boxes). I have read that cartridge has been stored at the correct temperature and humidity, this prevents condensation.

Also, what is the price of cartridges ? And where do you store them once they got written ?
