Hi I've just bought an MZ-NH700 from ebay, it did not come with a USB cable or a rechargeable battery. I've looked through the forums here and it seems that I need a USB Type A Connector to a standard USB Mini B Connector. However looking on ebay there are 2 types of USB Mini B, a 4 pin type and a 5 pin type. Which one should I buy? Also I'd like to buy a rechargeable battery for my MZ-NH700. In the minidisc.org browser it says "Rechargeable NiMH AA formfactor battery (NH-7WMAA)" I can't find any NH-7WMAA, so I was wondering which rechargable battery to buy? I look forwards to your help, and using my MZ-NH700
