Rand,

A quick followup to my last e-mail.

You should be using this part to duplicate the functionality of the
netmicro-sd interface.

Available at Mouser (assuming you in the States or can order from here)
http://www.mouser.com/Search/ProductDetail.aspx?qs=eXyjQBh9UFiI%252b3ceHxy2t
w%3d%3d Check this is the TVSOP48 package if that is what you used. Same as
netmicro-sd card.

instead of this
