thank you for your info, i will try soon

any instructions or detailed photos ?

hi
is there an Irix application similar to Autodesk 123D Design ?
if so, which one ?

unfortunately it's to applicable to electronic =(

i mean EagleCAD, OrCAD, Altium, Tina, etc: i can't see any equivalent software for Irix!

@vishnu
Ayam : nice to meet an other open source App

my purpose : i want to design an enclosure for my new SoC toy. When completed i will ask a service to print it. I think that asking a service to print an object (in ABS) is better then cutting and Dremmel-handling a plastic enclosure in order to make it to fit the electronic inside.

motivation : if Autodesk 123D is for PC and MAC (and it comes for free) why not a PC/MAC instead of an IRIX box ? Well, simply because i do like this way

more motivations : also may be because i do not have a serious Apple/PC, i mean i am equipped with a lady handbag laptop , and an Apple AirBook can't be really considered a laptop, it's a toy, which i am using like a dummy XQuartz/X11 terminal

yes, buy those applications are targeted for PC , while I wish i had these applications for Irix.

Dina is more productive than PSpice, and EagleCAD is more interesting than OrCad, especially for PCB 2 layers design, small projects (~ 160x110mm ), this because It costs the less, 300 euro for a decent license, and it does a great job! I had a macOSX basic license of EagleCAD on my laptop for hobby purposes.

The only open source CAD i know is KiCad, but i haven't tried to compile it for Irix, yet, and probably can't justify the use of Irix instead of linux on a common PC.

i am looking for purposed Applications for electronic & mechanical CADs, if they exist, for Irix.

up, still available, also i have a brand new (boxed) motherboard for C3600, the CPU is installed

UP, i have 2 units for sale

@guardian452
never tried, yet, but about kicad, why and what don't you like ?

i don't like Eagle/CAD so much, especially when i have to design a package like i had to do for the Playstation1's PAD and AVIN connectors (1). Also i do not like that packages are not exactly legacy-driven, i mean i have found a legacy-old-package for 68EZ328 (it's a pretty old CPU designed by motorola and used in PDA, it's 68000 core + built-in peripherals ) but i was not able to import into the current Eagle/CAD just because they completely changed the package-format without any feature to "import" legacy things.

That caused me to spend days re-designing all the packages from the scratches, and i had to use the Motorola/Freescale data sheet to have mechanical informations and quotes. Too boring, especially if i consider that the current OrCad for Windows is perfectly able to import everything i did on OrCad for DOS, and we are specking of projects done 20 years ago!



(1) it was a MAD project: the main purpose was to put an FPGA SoC inside the plastic case of the PSOne just to have a carrier for the RGB-S PSOne-LCD, i mean something portable to experiment HDL algorithms about … VDUs and graphical pipelines. The two Playstation connectors, the AVIN and the PAD, were used to connect the portable LCD, and "something" that provides a console. I routed two uarts in the PAD connector, one was used by the debugger, the other was used like CLI.

Adium on MacOSX seems to be working but i can't see anyone on IRC, i mean i am usually contacted by friends that see me on the channel while i am not able to se anyone. If you see me and want to have a call, feel free to call me as i do not see any events (people entering a channel, people leaving, i do not see anything)

sometimes i am used to use a more serious irc client on linux, but it's a more rare event

vishnu wrote: I remarked to Dennis that easily half the code I was writing in Multics was error recovery code. He said, "We left all that stuff out. If there's an error, we have this routine called panic, and when it is called, the machine crashes, and you holler down the hall, 'Hey, reboot it!'"

that's the pure Truth !

and that's the motivation why i have added a pretty motd to the kernel/panic.c, when the kernel panics it says " have you muued today? ", then forcing an auto-reset due to the watch dog timer (1), that's because using a panic is a dumb-cow method


(1) it's possible on a SoC, you always have a WDT on a SoC, and if it's enabled … you have to reset it within a window-time, if the kernel panics there is no WDT reset, if there is no WDT reset … the WDT will trigger, so everything causes a panic will also cause a reset of the (remote) machine

guardian452 wrote: I tried out adium and it had no trouble connecting and joining the channel (the latest version 1.5.10)

it joins, it connects, but i can't see any events, also the user list is empty
i know it is working because when i am online a dude i know is able to contact me

btw, i have the mac-port, i think i will emerge a better client

foetz wrote: after connecting you have to join a channel to actually see something

already done, but sill not working, also sometimes it crashes
i have emerged irssi /MacOSX (mac-ports), and it's working good, i can see the #nekochan channel
=)

i don't know what is wrong with adium, but i am removing it

so i was talk not correctly, thank you for the fix up!

I am interested in the DCD only.

TeamBlackFox wrote: This is the second time I"ve had to explain to you how rude it is to ask someone to part out a complete system when they're selling it as a uni

Hey ? take it easy, this is the first time i ask you something similar! Never asked you "to part out" anything before. And here i am not asking to part out a main part (like CPU, GFX, PSU), just an add-on (the DCD is not a main part). Last time i asked you to exchange (2) a cpu for an other, more specifically giving you an IP22/R5K@180Mhz fan-cool-less and receiving a fan-cooled. It was for a friend of mine, i wanted to give him a gift.

Also i do not think it's rude (1) "to ask", it's simply "a question".

To ask is lawful, to respond courtesy.


(1) with the meaning of "offensively impolite or ill-mannered"
(2) exchange, an act of giving one thing and receiving another

I can't use them. Italy plugs are different)

Damn the poor soul who takes apart an Onyx2 or Octane in this condition because that crap will ruin your compression connectors and/or make them fail intermittently.

so the IP30 is a bad system from this point of view because disassembling the the gfx out of the chassis is a trouble due to the dust, and you'd better put a protective cap on the compression connector. The same should be done by who wants to sell, before putting in the parcel.

I had dust troubles with the compression connector on the pci cartridge, solved blowing air compress.


i have to remove a gfx, when can i get a few protective caps ?

jan-jaap wrote: I think the problem is more that a dirty system is best left undisturbed because once you pull the thing apart the dust goes everywhere, including the compression connectors

Onyx2 is not a piece of cake, not a walk to disassemble, I understand, IP30 takes 4 houses for that (disassembly the PSU, all the coolers, front plane, and cleaning them carefully), but i think the dust problem hits us if systems are carefully careless. i often clean my machines, before disassembling I use to blow air compress, setted to "caress", strong enough to let the dust to go away, and so the dues does, it goes away, for the most.

but personally i had troubles only with the PCI cartridge, and air compress has reached the purpose.

Toshiba RISC 2xR14000 @ 600Mhz with FPU -> BogoMIPS 899+900 (SGI Octane2 with SMP CPU module)

I got an old CRT tube, it's 1bit of color (amber/black) with CGA timing, so I have to adapt it with an FPGA, designing my personal VDU (video display unit). I am also going to build a box-computer which aims to mimic the first Apple Macintosh

and obviously the actual result doesn't look like at all

I do not want to have to deal with Basilisk and macOS/Classic , the Woody Box aims only to mimic the design of the Macintosh/SE, I am going to use an fpga in where to design the VDU and my personal soft core, something that is a mash-up between R2K and m88K

the fw will be written in assembly, so It will be a toy, off course

It may be I will also interface the VDU with my 68060 board, in this case I will port XINU as ROMed OS.

edit:
this is a good lecture, other answers come from the wiky .

like that , it sounds <Happy>

above I asked which applications you could eventually find and run on Prism machines, and how good/bad is having to deal with *EFI.

uunix wrote: no doubt has a problem with English and …. his humour is utter crap

Ironically we get along for this reason, because your humor is different light years ahead than mine while my English course is really a utter crap, so we get along because you are the One I trust when you appreciate any progress

thank you =)

the Xinu port involves a ROM emulator I am building in the free time, while the SoftCore involves a TAP and a debugger interface I haven't completed yet. So in both cases it will be a long story.

For the near future I have other plans. I am waiting for an old CGA-ISA/16bit card I have bought from ebay. This way I will be able to test the CRT's electronics, then I will use my DSO to understand the CGA-timing. I still have a few (a lot) of dubs about. The CGA-ISA/16bit card can be plugged into a PC, so I cold run linux, or DOS. Just to see how pretty or ugly it goes on the CRT's screen.

I'd like to see an ADA compiler on Irix.

..

About Irix: i'd like to see "geany", as I feel I miss an useful IDE. I am a bit busy with other things at the moment, to care about Irix, also my Octane is still dead, and my friend doesn't want to put his IP28 online for more than 2 days a week (yesterday it was Online, I was lucky)



Geany is a powerful tool, unfortunately has to deal with GTK+, so … it may hurt hard. I am used to use it under linux just because I do not have to care about GTK+, ubuntu already has things configured and installed.

amazing

edit:
p.s.
I bought a paper copy of an old the Byte Magazine which talks about 68K unix ($5 on ebay), the first implementations. dr dobbs has a similar article. Byte Magazine issued also 2 marvelous articles about R5K, and R10K. Unfortunately I do not have them, but I read them in my university. They have a copy in their library.

I am on the road again, but hey guys ? Don't tempt me to power its gears with a steam engine, the EAT circuit is still missing of any feedback, so ... the technology behind the electric bean is '50 (and any other atavic regress, could send it back to 1800)

No doubts Steve Wozniak, at the beginning of Apple, did prettier woodworking. I was able to hit all nails with the hammer, without hitting (too much) my fingers. I made progress.

@Cory5412
I am still waiting for a working ISA16/CGA video adapter in order to have something already working to repair and tune the CRT electronic. It needs a lot of tune up, and I have to learn about CGA timing, then I will switch to an fpga to develop a custom VDU.

hamei wrote: People getting a degree in computer science should be required to pass a course in remedial English

here we are required to both pass the TOEFL Test of English as a Foreign Language and the the A.I.L1 (Artificial Intelligence, Level1).

In the first case the minimum acceptance threshold is 1/4 of the TOEFL full scale, if you get a better result, you can claim money back (it's 180 euro), in the second case you have to write an App decent enough to demonstrate you have a few skills in Natural Language Processing.

If you pass both of them, you can get your L2 degree, so I have already bought a full Oxford CDs set, an English Grammar and Dictionary for Dummies, a few movies with subtitles (e.g. Matrix Reloaded, Sex&TheCity), and In am seriously thinking about simplifying the whole English Grammar in order to make my NLP program able to handle it with simple pattern matching techniques

I am afraid that passing the TOEFL and the A.I.L1/NLP will not save you if I will ever be asked to write a piece of computer software

I haven't checked Insignia SoftWindows95 yet (because I am still without a working SGI box), but probably the answer to my question is: do not expect anything serious about the handshake, the breaks, and everything needs more lines and attentions than a NULL-modem.

I have posted in the RiscOS topic a few links about all the troubles I have found with GEMINI. Who? What? In short GEMINI is what happens when you try to share the serial line between a dosbox and the physical machine (horror story, be warned)

I have a marvelous m68K development toolchain, SierraC, and this toolchain is fully working without any limitation of the demo version that Motorola (today acquired by Freescale) was used to include with the EVS board. The demo limitation was related to a 100 lines in every C file. No more than 100 lines per module, plus other limitations with the linker script. When I bought my EVS board from a dude on ebay I was lucky and the the parcel came with a full working Sierra C disks, plus other floppies with debug processor interface (similar to DDD + GDB) and a few professionals tools, that is a pure WOW, but … the bad side is that all of these things work only for DOS. Wine (under linux) is not fine with them, while Windows95 (aka MSDOS7) is fine too, so I was thinking that Insignia SoftWindows95 was great!

Well, from the the pure software side, Insignia SoftWindows95 is really great! the problem is .. you are fine with the toolchain, you can compile and build whatever you want, but then have to talk with the board, and … the debug processor is a very horror story because it uses a full-modem connection, with DCD, DSR, DTR, RTS, CTS, all of these signals plus "breaks".

Under RiscOS, there is a GuestCard with a 486DX4 CPU, plus an ASIC chip, called Gemini, that performs

• Bus translation ARM <-> Intel (luckily they are both Little Endian)
• Interrupt delivery and mailboxes
• Address space trapping -> emulating ISA peripherals, UART, LPT, pATA, sVIDEO, kb/mouse

!PC/Pro is the software side, and it's able to control the x86 card, and to share all the host resources. Everything is fine with the LPT port, I can attach a BDM cable and use a DOS program to control it. Unfortunately the serial line has other troubles because Acorn didn't respect the RS232 standard, and also they did not use 8250, 16550 chips.

under !PC/PRO, every DOS program makes a BIOS call for a serial service

• the “BIOS” pushes the data to the ASIC
• the ASIC works a bit like the Pi GPU with a mailbox scheme, it would probably be able to raise interrupts on either processor and pass data between them
• RISC OS will respond to the ASIC, read the data, perform the service, and pass data back if appropriate

In the theory this working scheme seems fine, but ... I have understood the supporting DOS Applications that directly access the PC hardware sounds more complex than how it seems, so actually I have bought a genuine 586 PC from ebay, and I have loaded it with OS/2 Warp3: the OS/2 legacy DOS support is working good, and I am able to multitask up to two BDM DOS applications , that is extremely good if you want to toy with 2 target boards at the same time

extremely interesting thread, unfortunately I can only contribute like one of your fans =)

wikipedia
Freescale was one of the first semiconductor companies in the world, having started as a division of Motorola in Phoenix, Arizona in 1948 and then becoming autonomous by the divestiture of the Semiconductor Products Sector of Motorola in 2004

good to know, I was wrong

I was focused on the MC68332UM: with the EVS I got a lot of books, and I have noted that all of these old paper books marked " Motorola " have been renamed " Freescale " without any other difference in the context of the new digital form (PDF).

Unfortunately Freescale says that, from their point of view, 683xx and the EVS are legacy products, so probably there is no way to open a technical ticket to ask their dudes for a few informations, software, or tips. I have already tried, and … they have said they can't help.

Sorry the DIBUG tool is quite old and EOL for many years. We do not provide any technical support for this tool any more. I do not know from who you got the DIBUG tool, I had tried to find the tool from our data base, but found nothing.

Technical Support
Freescale Semiconductor

The guy from who I got the DIBUG tool was an old Motorola semiconductor employee.

I was struggling to realize an engine that needs 40 Ampere, I was thinking that 40A were strong enough for a poor IGBT when I met a dude on the freenote: he works for CERN, he said that, from their point of view, this IGBT is for "low power" equipments.

It's 2500 Ampere 1200 Volt , my universe has warped, cracking up, I need a pill X________X
