I'm new to SGI systems, can somebody help me find out what I've got?

Hi everyone! I just bought an Indigo 2 from craigslist and I'm having a tough time figuring out specific hardware is inside this thing. The guy said was that it was owned by General Motors and that it was maxed out.

The model number is CMN8007Y75

Sorry if this is the wrong place to post this!

Greetings!

This is the right spot, yep - though the model number itself unfortunately doesn't have much insight as to what's inside of any given system. (Especially these days, where things have been more than likely swapped about at some point in the last 30 years.) Assuming the system powers on, there's a few ways to learn what's going on without opening it up, such as connecting everything up and running the hinv command from the program monitor; beyond that, the best thing to do is to take a few pictures of it. You can determine what graphics card you have without taking the cover off, just by looking at the ports on the back - and inside you can see things like a guess on how much RAM it has and what generation of CPU is installed.

There's some good resources here, or you're welcome to send us some pictures and we can help out.

You can connect it to a serial terminal or USB to serial on your laptop - at 9600/8/n/e and boot without keyboard or video connected. You can hit ESC and in the PROM menu that appears you can enter the Command Monitor and do a 'hinv' command to print out what is in there.

System Maintenance Menu

1) Start System
2) Install System Software
3) Run Diagnostics
4) Recover System
5) Enter Command Monitor


Option? 5
Command Monitor. Type "exit" to return to the menu.

like that.
I don't have the right kind of monitor to plug it into at the moment, but I'm looking into adapters.

I took a few pictures of the inside. Should I take the big heatsink off and take a picture under that too? I didn't want to damage anything.

Part number of the CPU is -> IP22 R4400 250mhz (2mb SC)

Hard Drive is XP32150 Quantum 2.1GB SCSI 50-PIN HARD..

Memory is full but you'd have take a few out to see the size....

Thanks Mike, the first bank appears to be Kingston KSG-16/R40A modules. I'm not sure if the whole bank is 16MB total or if they are each 16MB.

The second bank is a much thicker module but it is also labeled KSG-16R40, and the third bank is what appears to be single rank NEC modules with this code printed on it:
MC-424000A36FF-70
9524YE1611

Do you know what capacity these NEC modules are?

Looks like 16MB x12 -= 192MB in the system. I've never had an Indigo2 so someone else might chime in. I read they can have up to 384MB , or later models 512MB (which might be the R10K versions).

Ian Mapleson has been along time reseller of all things SGI his site is filled with useful stuff.

The Indigo2 Buyers Guide is probably a good place to start.
