Hi Barry and others, I'm still looking for connectors, right now I'm using a 100 mils edge connector saved fro an old cable, but any floppy disk cable will do. You can try to buy a MMC connector from AMP p/n# 97-8415-01-1 Please let me know if you were successful buying it. Would you mind to share your code to access the MMC? I also doing a PC reader for it.
