I sold executor some devkits for programmable SATA-2-SATA bridge chips which (if developed) could have become some great 360 products.
A banked hard drive. Would allow you to use literally any model and any size hard drive but cut into multiple 120GB areas (switchable offline). It would have a USB connector for easy transfer of files to/from the PC.
A DVD-ROM bridge. Basically it sits between the xbox and the DVD-ROM on the SATA connector and intercepts all traffic, effectively replacing patched firmware, no need for key extractors etc.
But things went silent over a year ago

First the RROD kit and now this. Team Xecutor what happened to you?
