<h1>Modification and Upgrade DD90 352</h1> <p>To modify the DD90 352 floppy disk drive for Thomson computers, so as to avoid disconnecting the DIN 14 connector during use of the CS91-280 controller and sdmoto.</p> <b>Warning:</b> <p>This modification is done at your own risk. Modifying the drive may damage it, which will void your warranty;-). You assume full responsibility in case of malfunction or if your drive/computer is damaged or no longer functions.</p> <p><b>How to Proceed</b>:</p> <p>+ Identify the two points on the PCB (see photos). + Desolder properly. Use a cutter to cut the contact between the two points. + Solder two wires into these holes and check with a multimeter that there is no contact. + Solder them to the switch + Print the facade, put everything back together and you're done!</p> <u>Note:</u> <p>I use these switches purchased on Aliexpress <a href="https://www.aliexpress.com/item/New-10pcs-21MM-15MM-Red-Black-each-5pcs-Push-Button-Mini-Switch-6A-10A-110V-250V/32680087856.html?spm=a2g0s.9042311.0.0.27424c4dBvJVzN">Switches</a>.</p> <p>If you use a different size, be sure to modify the provided OpenSCAD file and generate a new STL file.</p> <p>Depending on your 3D printer calibration, you may need to adjust the width of the facade and the holes. I intentionally added a small margin for this purpose.</p> <p>I printed this facade in PLA, but due to its thin thickness, ABS might be more suitable as the facade tends to bend (but remains stable once installed).</p>
