Re: Installing SunOS 4.0.3c on SPARCstation IPC

Found this reference to the "patch" for 4.0.3c: http://www.sunmanagers.org/1991/0313.html It turns out that if you have Sparcstation IPCs (or SLCs - 4/20?) with CPU board numbers 501-1680-03 and greater 0MB Sun-4/20 CPU Board 501-1748-03 and greater 0MB Sun-4/20 CPU Board 501-1689-08 and g...

Re: Installing SunOS 4.0.3c on SPARCstation IPC

Thanks! I do have 4.1.2 running on it now but I was hoping to go older simply for the sake of going older. Sounds like it's not worth the hassle on this machine, though. I'll probably just put 4.1.4 on it and call it good. I believe at release it shipped with 4.1.0. I put some info/pictures of the m...

Installing SunOS 4.0.3c on SPARCstation IPC

I recently revived a dead SPARCstation IPC (bad output caps in PSU) and wanted to get the oldest possible OS running on it, which as far as I can see *should* be SunOS 4.0.3c. I have the 23-floppy install distribution (readily available online) but it seems to give me all sorts of problems. I can bo...

Re: Vintage Computer Festival August 5 and 6

Nice pictures! It was someone other than smj who was kind enough to offer to ship the machine to me, though. Was it you who was selling the HP Integral as well? or was that smj's too? Wish I'd known so many nekochan folks would be there, I didn't even think to check here until after I got back. It w...

Re: Vintage Computer Festival August 5 and 6

I really wanted that Solbourne, hope it went to a good home! Would have been a little awkward carrying it through TSA though.

Ended up taking one of the PA-RISC boxes in the "$5 donation" pile after someone was nice enough to offer to ship it to me. Not sure if he's on nekochan or not.

Re: Unhappy Octane frontplane, capacitors leaking. Anyone spec'ed replacements?

Thanks, I did measure the diameters as shown above, but I'm trying to definitively determine the capacitance and some other parameters (like ripple current rating, ESR, etc.) I suspected they were 6.3V based on the '6' markings but thanks for confirming that! I guess I should probably just select th...

Unhappy Octane frontplane, capacitors leaking. Anyone spec'ed replacements?

I have an Octane FP1 that doesn't go, I think it is a very early version: REV A with a 9726 datecode on it. It seems like it almost wants to work, but I can't get it to boot farther than lighting up the BaseIO and QA LED (no Heart LED). I've tested all of the other components (IP30, PSU, graphics) i...

Re: Octane MXI board TRAM problem - any fix, or is my TRAM toast?

After doing some more experimentation I'm back to thinking one of the TRAMs is indeed bad. I haven't worked out a way to figure out which one is bad (aside from either buying a SI card to see which one doesn't work right in it, or buying another TRAM that is hopefully good). I think it definitely is...

Re: Octane MXI board TRAM problem - any fix, or is my TRAM toast?

the IDE tests do not reveal which TRAM is bad, it simply says "tram test failed" and says the whole MXI assembly is bad: http://i.imgur.com/gTB0huP.jpg 030-0957-003 is the SSI/MXI mainboard, of course. When running IDE without the TRAMs it passes all tests. I've done some swapping around o...

Octane MXI board TRAM problem - any fix, or is my TRAM toast?

So, I picked up an MXI board for relatively cheap but I think one of the two TRAMs is bad on it. It fails IDE in "mg_tram_rev_nobuff", and any GL stuff using hardware textures shows up "interlaced" - see photos for examples. http://i.imgur.com/DCGjZnr.jpg http://i.imgur.com/JUHd0...

Hey guys, thought I'd drop this here as some folks here may find it useful as an alternative to DINA - my IRIX netbooter called 'irixboot': https://github.com/halfmanhalftaco/irixboot It uses Virtualbox and Vagrant to launch a disposable VM for netbooting IRIX installs - including extracting EFS dis...

Re: WTB Indigo2 Teal Feet/stands or cdrom sled/drive

Sorry about the confusion, I updated the post to say sled instead of tray. I'm definitely looking for the proprietary sled with the 80-pin backplane connector. I'd generally call the thing that you put a CD in to a older cdrom drive a "caddy" and not a tray.

Looking for the teal plastic feet/stands and/or the cdrom sled with or without a compatible CDROM drive for an Indigo2.

Re: Indy memory problem - runs with 4x32, but not with 8x32

Ran memtest, dram and ldram and they all passed. I let it run the normal bank of tests including the graphics tests and those all passed as well. I can also boot into fx just fine, but booting into IRIX installers fails - kernel panics each time. I tried IRIX 5.3, 6.2 and 6.5.22. The miniroot copies...
