GN has been following the Xbox 360's various hardware alterations for quite a while now, and it's been a pretty interesting story so far. From the original, RRoD prone Xenon mobo to the Zephyr and Falcon successors as well as the upcoming Jasper design, there's been no shortage of news in the field. Today, as a matter of fact, we've got a look at another Xbox 360 chipset, the extremely rare "Opus" as discovered by member Electric Tunder on the Xbox-Underground forums.
Designed specifically to help Microsoft recoup losses on RRoD'd hardware that's been returned for repairs, the Opus chipset is a Falcon-generation mobo that'll snap into original Xenon Xbox 360s. Because it is installed in refurbished Xbox 360 launch chasses, the Opus lacks HDMI-out. It does, however, feature the Falcon-era HANA video chip that supports digital output, which means a really skilled modder could potentially retrofit such a connection.
The Opus also looks to be sporting the 65-nm CPU from the Falcon chipset due to the new-style heatsink mounted on chip. The Opus is, in essence, simply an HDMI-lacking Falcon chipset that'll fit in original Xbox 360 cases. Owners of pre-HDMI Xbox 360 consoles who send in dead systems for repair should expect to start seeing these guts in their repaired consoles.
