Stephan Fuelling

Hi, my name is Stephan Fuelling. My church has an FX-20 with an MDR-1 3" floppy drive. The floppies are slowly failing, there is music on from an organist that passed away a few years ago. I am in the process of conserving the recordings by downloading the data from the MDR-1 to an SD card. I have successfully interfaced the MDR-1 and just today was able to load down a 25 minute recording. I used a Kingst Logic Analyzer, 16-bit, to first understand the data structure and the handshaking. Then I interfaced it with an Arduino Mega 2560, since I needed a complete 8-bit port to interface with the MDR-1. I simulated the Yamaha clock output with a 555 timer but in the final design I want a more stable clock. I plan to build a customized 'shield' for the Arduino, with a DB-15 jack so it can be connected to the MDR-1 or the organ. Just to let you know...
