[rescue] SGI

[Thomas Pelki]

Hi John-Paul,

Thank you for all the information, Below is what I know about mine so far:

The model number is CMNB007Y100

has the 3 card set graphics (extreme graphics) 013-8764-001
Missing whatever the card was below the graphics and no i/o plate
12 sticks of RAM (still trying to figure out how to remove the CD-ROM base
so I can get to the CPU and the RAM)
No CDROM or CDROM sled
9Gb Hard drive in the sled.

broken keyboard and mouse (UPS now has in their possession for a claim)

-Thomas
