This can be used in your Amiga 1200 if you have the modulator box removed. It en houses a microSD extender, that you can ordered cheaply from internet. Since the modulator is fairly close to the IDE connector, this is ideal to use it for the main drive with an IDE to SD and an SD/microSD adapter (use a 15cm extender) It's not perfectly centered for the hole in the back, because the original modulator is asymmetric, and the sd slot barely fits the space as it is. It doesn't cover the top of the hole. You can mount the bottom part with a pair of M2 screw to the motherboard and put the top on with 4 M3 screws. Length of the screws should be 4-8mm. Only printed parts, hardware NOT included.
