The collected works of StephenT

Hey all! I represent the Goodwill Computer Museum in Austin, Texas. We've got a sizable collection of most of the usual SGI workstations, but we're interested in restoring a Power Challenge GR and Onyx that we've got in various stages of disassembly. We have the entire enclosure for the Challenge, but only the front panel for the Onyx. All of the boards were removed from both systems and came to us in dusty boxes when we received the collection. We could really use y'all's help identifying exactly what we have in the way of hardware before we get started.

THIS GALLERY contains photos of all of the boards and hardware from those boxes. I omitted photographing boards of which we had multiple identical copies (such as what I believe are memory boards). Each photo has a 3-digit number at the end, so when identifying a photo please use this number. At the bottom of every photo's page is a link to download the full resolution, in case you need to identify chip labels or other surface writing.

We're looking to put a full system back together from this hardware if possible, and this would give us a great start. Thanks so much for your help!

UPDATE: Here are the parts that have been identified so far:

016: Bottom of 015
015: SCSI hard drive [PymbleSoftware]
014: SCSI hard drive [PymbleSoftware]
013: 030-????-???: Quad IP19 processor board for onyx/challenge, missing a bus heatsink [freq]
--^-- Based on the fact that 010 is a 150MHz board, is this one likely also 150MHz?
011/012 : 030-031?-004 unknown backplane [kshuff]
010: 030-0374-007: IP19 Dual R4400, 150MHz, 1MB SC [freq]

008 030-0614-004: MC3 memory board, looks like 256MB installed [freq]
--^-- I will check on the memory modules to confirm the amount.
007: Close-up of 006
006: 030-0607-001: MC3 with a laughable amount of memory on it
--^-- Oddly enough the 0607 # doesn't appear on the Wiki page as a board the Challenge/Onyx used.

Yep! "The" Goodwill. And yeah, we do get most of our stuff via donations. We share the building with the regional computer recycling center, so we naturally get quite a bit of vintage stuff just showing up on our doorstep. Occasionally we get straight donations to the museum though, and those tend to be in better condition. You never know what's gonna come through those doors, though! It's like Pawn Stars for geeks.

check out the Onyx wiki page, there is a partial list of Onyx and Challenge boards including part numbers.
http://www.nekochan.net/wiki/Onyx

This is almost fun.

I do not. And thanks for crushing it with the identifications! I found a lot of the part numbers by cross-referencing the wiki and your initial info. I agree, this is kinda fun!

kshuff wrote: 012 and 026 are backplanes aren't they? Why would you remove them?

Originally the Onyx had a cracked backplane, which the owner removed to install a replacement he bought. He never put the new board back in. The Challenge does have a backplane installed in the chassis. I need to take a photo of it and check the part number.

Thank y'all SO much for the quick responses! I am going to create a new thread in the hardware section geared toward determining what all we can do with this hardware.

jan-jaap wrote: Looks like a Challenge GR is an Onyx stripped of it's graphics boards. Since you have the graphics boards and Onyx front panels, I'd turn it into a real Onyx You're going to need several OLSes (power supplies), power boards and a system controller that plug into the back side of the backplane.

Another invaluable source of information about Challenge/Onyx and Crimson systems is Simon Pigot's old site. It's no longer live, but mirrored here: http://www.sgistuff.net/mirrors/sgi/

Good luck!

Thanks a ton! Looks like I have a LOT of reading ahead of me before I get to plugging boards in. We do have 3 OLSes in another box that look to be in decent shape. I think the System Controller board is in the Challenge chassis, but I'll have to check on that. I would love to turn the system into basically an Onyx rackmount. From what I'm reading it looks like we have most of what we need to make that happen.

Oh, if only you could see what we've got on our pallets. I'm not sure what terminal that is on top of the SGI but I'll check next time I'm in there.

sybrfreq wrote: The list on the wiki is incomplete, I threw it together one day when I got bored. I've added the 0607 to the list.

One thing that would be nice would be to organize photos and link them in the wiki page. We could do this for other machines too

Agreed! I will work on uploading my photos to the wiki and linking them to the appropriate entries.

Just checked today. Turns out it's a Heathkit "H9 Video Terminal." Not sure how long we've had it or how it ended up on top of the SGI. Pretty sure it doesn't have a 13W3.

Hello everyone,

Sad news. The Goodwill Computer Museum is shutting down and getting rid of their whole collection. There's a complete Onyx rackmount system with RE2 (in a Power Challenge chassis) that was being restored. It'll get recycled unless one of y'all would like it.

Relevant Threads:

Onyx Rackmount Restoration (includes list of boards)

Help identifying some SGI boards (original thread)

No idea on the functional status, but the system has been kept indoors, stationary for about 10 years.

Available for pick up in Austin, Texas (or you can pay for LTL shipping). DEADLINE FOR INQUIRIES: TUESDAY, MARCH 17th

Please PM or email me at [email protected]

Thank y'all for the quick responses. Totally understand the distance issue.

The rest of the collection is being sold via the Goodwill eBay account:

Many items have sold already, others are being added almost daily. Keep an eye on it!
