Sega’s FD1089 security module reverse engineering part 2:
The FD1089 module variants from Hitachi / SEGA were fabricated in a plastic case, on the back of the module a epoxy layer is visible together with two rows of pins arranged as DIP64. This arrangement mimics a standard 68000 CPU as intended by SEGA.
The sample shown below features the SEGA code 317-0013, this indicates the module was used as part of a Enduro Racer game board.
