## Tandy 1000HX Floppy Mount for Gotek Emulator Board. This project requires various modifications to the Gotek, including soldering: ### Parts Needed: * A Gotek floppy emulator compatible with FlashFloppy firmware. * Two identical OLED 0.91" 128x32 screens. * Seven 2.5mm self-tapping screws. * An amber or yellow 3mm LED. * A USB flash drive, preferably flat or micro-sized. * Black electrical tape. * Custom wiring and soldering are required. ### 3D Print Notes: * The front face should be printed facing down. * Printing without supports is possible, using low infill settings. * BuildTak-like build surfaces work well for the front face to match Tandy plastic. * Buttons may need sanding to fit properly. * The platform STL includes a small standoff for mounting in drive bay A or B. * The USB Surround STL should be printed in black or painted black. * The wedge can help align the front face up and down. ### Gotek Modifications: You must make several physical modifications to the Gotek before using it in a Tandy 1000 HX. See Adrian's Digital Basement YouTube video "How-to: Installing a Gotek in a Tandy 1000HX" for technical details, including: * Several pins need to be removed from the Gotek. * Power must be provided from the existing drive or extracted from the ribbon interface. * Use FlashFloppy 3rd party firmware to support OLED screens and 720k disk images. Additional modifications are also needed: * Additional wiring is required to support two OLED screens connected in parallel. * The existing up/down buttons on the Gotek PCB must be un-soldered and removed. * The existing access LED must be un-soldered and removed. Suggested FlashFloppy FF.CFG settings: ```bash display-type = oled-128x32 oled-font = 8x16 ``` ### Build Notes: * Create custom wires to connect the two OLED screens together in parallel, following the directions listed on the FlashFloppy site at https://github.com/keirf/FlashFloppy/wiki/Hardware-Mods. * If soldering pin headers to OLED modules, try to keep them short and flush in the front. * Before fitting OLED screens into the front face, use electrical tape to cover up the bottom line of text on one screen and the top line on the other. * Mount the correct OLED into the correct position on the front face, using hot glue if necessary. * Insert the desoldered Gotek up/down buttons into the platform with the buttons facing forward. * Suggested to cover the underside of the Gotek with tape to prevent shorting against the buttons relocated below it. * Wrap a little bit of electrical tape around the 3mm LED light so it only shines forward. ### CAD Files: * The original Fusion 360 F3D file is provided, along with an exported STEP file for other CAD programs. * The CAD files use an OLED reference CAD drawing by Stilet Fox at https://grabcad.com/library/oled-0-91-128x32-1
