Now this is commercial software. But on archive.org ...

Mods: Feel free to delete this posting, but my guess it's a legal offering.

Archive.Org seems to skate under the Fair Use defense for everything that they do. Mirroring web pages without prior permission is not sanctioned by the copyright laws either.
They have a project to upload and share every CD-ROM ever published.

Looks like a good site where things like hotmix titles could find a home...

I tried to google specific SGI CDROM's and google returns a link to the archive.org entry. So posting links to these entries at archive.org doesn't seem to be a problem, and shouldn't get you into trouble.
You can actually download CDROM images, although i'm not completely sure these images works, i.e. contains all the files and information.

Among them is an IRIX 6.5.6 installation and overlay, 7.3 compiler execution environment, various 3rd party software, various hotmix CD's, 1600SW drivers, basically the works.
Needless to say, i am a bit surprised :)

Disc images appear to be straight 'dd' style images.

If they manage to keep this online I've got a couple of hundred more for them :)

OK, I downloaded a couple of disc images. Most appear to be good, but it appears some of them are truncated.

For example, "O2 Demos 1.1.1 for IRIX 6.3 Including R10000" is a 225MB disc image. It has an SGI disk label (volume header) and an EFS partition. In SGI disk labels, partition #10 is always the entire disc. You can use this to sanity check the disc image length (on Linux):

Code: Select all

dvhtool -d <EFS image filename> --print-partitions | grep "Part# 10" | cut -d ',' -f3 | awk '{ print $2*512 }'

will return the content length of the disc image. The actual disc image file should be at least this many bytes (most are slightly bigger, this seems to be a side effect of how they made these discs back in the day). For the O2 demos, that's some 615MB so this image is well short. An attempt to loop mount it and copy the files will result in I/O errors.

The same applies to:
Cosmo Software May 1996 for IRIX 5.3, 6.2, 6.3 and 6.4
IRIX 6.4 RECOMMENDED REQUIRED PATCHES 4/98
O2 INSERT FIRST

I downloaded only a handful of images -- I had most already. It makes me want to sanity check the contents of the images for CRC errors before I add whatever I got here to my collection ...

..

Did you retry any downloads again just to be sure? I downloaded about 60 scanned PDFs of old DEC manuals from archive.org recently, but I'd say about 15 were truncated. On a second attempt at the bad files, some were ok, but some were truncated again. So it could be due to bad downloads at that site.

If you go to the page for the CD: https://archive.org/details/sgi_O2_Demo ... ing_R10000 and hover over the "ISO image" download link, it says it's 212.2MB. That number is way short.

I was going to respond with a portable version, but there is no portable 'od' or 'hexdump' with correct handling of other-endianness. The best I found was 'xxd' (always uses big-endian), which is not part of POSIX.

Code: Select all

#!/bin/sh
TMPF=`mktemp /tmp/efslenXXXXX` || exit 1
echo "ibase=16;read()*200" > "$TMPF"
xxd -u -g4 -s432 -l4 "$1" | cut -d' ' -f2|bc "$TMPF"
rm -f "$TMPF"

I also found that the "O2 Demos 1.1.1 for IRIX 6.3 Including R10000.img" and "Cosmo Software May 1996 for IRIX 6.2, 6.3, 6.4 and 6.5.img" were too short.

It is worthwhile just trying to burn one of those shorter images to CD to see if it might work? I thought that some CD tools created larger images (with some sort of buffer bytes) - but I am not sure about that (can recall seeing/reading this once)...

We're not talking about some buffer bytes here, but a ~ 600MB image truncated to ~ 200MB. Nu burner can make up for that ;)

I skipped the physical media and tried loopback mounting the disc image in Linux. If you try to copy the files off, you'll get I/O errors at some point.

Archive.org has alot of good stuff. Stuff that would've been quite difficult to get a decade earlier.

Hopefully they add more to the collection. Perhaps I'll offer up some of my stuff too.

My former inside guy at sgi (he's at Cray now) told me many years ago that sgi management had long since ceased to care about Irix installables showing up in the wild. I mean, if you called sgi and asked to buy an Irix license would they even sell one to you?
