Amiga 1200 Backdoor Extender kit 4 functions

thingiverse

Updated 25. January 2024 with the U3AF USB Adapter.This is a remix of Amiga 1200 Back Door for HDMI and Micro SD Card Extender but with added USB and Tactile switch (for reset button or RGB2HDMI control etc). There are 6 variants + a Tactile blanker if not needed.The variant is about with or without brim and the shape for the lower HDMI connector.By "brim" I mean a brim that goes a bit outside the 1200 case which is normally fine but I chose to leave options without it for those who wants limited to only the cutout space.This should fit a Pistorm 32 light nicely…I am using Variant #1 (and tested #2), the others are optional for you if needed.Pay attention to the MicroSD Card to make it fit properly inside (and test the memory card) before gluing with some superglue underneath the extender. The MicroSD card might be a bit stuck in the start but should loosen up when used a bit.Its quite crowded inside so be prepeared to cut a bit on the plugs for a tight fit.I have used machine screws on the USB connector and some small wood screws for the HDMI. For the bottom screw I use a PC powersupply screw, or you can cut a larger wood screw.Solder wired in on the Tactile switch before snapping it in place.
