I have gotten my hands on a Trusty 1.4GHz interposer and am in the process or reproducing it. I already have a schematic and partially routed, but the design is going to take a significant amount of work, and I am looking into getting it professionally delayered and scanned.
I am a Physicist, and electronics enthusiast. One of my biggest passions is in the Original Xbox. Many of the modifications that have been done in the past (primarily add on boards, CPU upgrades) have been a closely guarded secret... My goal is to rediscover, re-engineer, document the requirements and release as much information on all of the hardware designs that have been lost. I build and sell many upgrade parts for the original Xbox including HDMI adapters with integrated digital audio, OGX360 controller adapters, and much much more.
