I'm coming into possession of an Octane2 so my Octane is no longer needed by me.
Specs:
300MHz R12000 MIPS CPU ( Upgradeable to 2 x 600MHz R14000 )
1GB RAM ( Expandable to 2GB )
V6 Odyssey Graphics 32MB
72GB 10k7 RPM SCSI HDD ( Takes up to 3 80 pin SCA UW SCSI drives )
IRIX 6.5.30 or can come without an OS
Free PS/2 SGi Keyboard
I used this as a daily driver, it can browse using the Firefox port on IRIX well, even with JS enabled, play 480p XviD video and function as a fast and powerful UNIX workstation while embracing the concepts that made the Amiga great.
You can use Photoshop 3.0 and Illustrator 5.5 on it, as well as Pro/E and Maya. Definitely a great workstation for any retro computing enthusiast.
