For those that want to know,
After reading over the CD that came with the device I found the source site which is https://www.sd2iec.de/. While the ebay auction I found the thing at was http://www.ebay.com/itm/SD2IEC-SD-Card-Reader-for-Commodore-64-1541-Disk-Drive-Emulator-C64-C128-VIC-/282408379384?hash=item41c0d9e3f8:g:izMAAOSwA3dYiLz7
My question is would we need to replace this or upgrade to a better one?
