Amiga 600 Accelerator And RAM Expansion

Mounting holes on the Accelerator PCB match with the HDD cradle and accommodate a M2 screw to provide stress relief for the PLCC68 socket. SukkoPera has a great guide on how to prepare the PLCC68 socket as some small modifications are required. His how to guide is linked here;
