My rarest is almost certainly the NTT Indy (thanks to Elf! More info here), but a one-of-350 Crimson Jurassic Classic earns an honorable mention.

Also worth an honorable mention is an O2+ that I'd happened to score an awesome deal on, thanks to the magic of Yahoo Auctions Japan. It took three months to arrive via barge, but it showed up in immaculate condition -- and with the original hard drives.

So it turns out that this particular O2+ doesn't boot into a normal IRIX login prompt: it has a copy of CARTO, which is a wildly specialized piece of cardiology software designed to measure and display the movement of voltage across a human heart for the duration of a heartbeat. The colorful object in that third image there is a real human heart scan: this one was post-surgical, as the red marks show where a surgeon had cauterized the heart. The most recent scans on the system date back to 2008: I have no idea how a piece of decommissioned Japanese hospital equipment got out with all of its data intact, but it came as a total surprise to me when it arrived at my door.

It's certainly the machine with the most unique and slightly eerie history in my whole collection; computers with a story are always more interesting.

Hi Elf! Its a great case but heavy as a tank though. I picked it up around 2002, fired it up to make sure it worked at the time and it has been sitting since. Looks like the mainboard may be custom. Ian Mapleson list an IP22 variant on his site and Mashek has an IP22 version on ebay, but I haven't run across info on an IP28 version of the GEMS I2. I need to still pull the mid-plane to get at the main board part number. The the db9 on the back runs into the custom electronics in the first picture below. Looks like there was some control boards in the card cage that I didn't get, based on the schematic.

From Ian's page:
"Motherboard for R4K Indigo2: 2750 UKP (SGI PN 030-0844-004. V11 PROM fitted, but add extra for CPU if required. This is a special board for medical systems) "


this was definitely from a ge cat scanner console, the motherboard had some "special" trace wiring on it to force people to pay ge 35k for a replacement. There might still be someone still using this old tech

Out of interest, is it a R12k system or RM5200/R7k system?

I've just bought a pair of RM11's to upgrade my Onyx2 desk side to IR4.

I've never seen this hardware demonstrated, so it must be pretty rare!

Just found this topic, trully impressive stuff like the proto indigo1 with Pi color....

For my own, I think my Pi 4D/20 from 12/1988 (one or two mothn after introduction if I remember correclty, no TFLU chassis) is my "rarest machine".
