Reverse engineering of Sega’s System 16 Hitachi FD1089 cpu security module by Eduardo Cruz:
I’m glad to announce the successful reverse engineering of Sega’s System 16 cpu security modules. This development will enable collectors worldwide preserving hardware unmodified, and stop the general discarding of Hitachi FD modules.
The project is right now involving external testers so expect further details and full disclosure over the coming weeks.
