It looks like something is missing on my Disco Fever back-box. The MPU is only secured at the top. Looks like there should be something to secure the lower part of that board. When I got it the MPU only had two screws - the driver board had no screws - it was just hanging by the interconnect. If I secure the driver with 4 screws do I need more than the two screws on the top of the MPU?
Thanks
Bob
