SD/MMC Card Connectivity: Card Readers

ASUS Eee PC 701 4G	Some internal upgrades: to install devices internally, more USB-connections are needed this can be achieved by routing the D+/D- signals from the southbridge/controller to a 4 port USB-hub.

SD/MMC Card Fits in Floppy Edge-Connector	You can attach a SD memory card to any homebrew DIY project that has a few I/O pins, using ordinary connectors you probably have right now. SD cards are very popular for this purpose, because they only need a few pins (using SPI mode), and can be driven with simple "bit-bashed" SPI serial communications protocol, using free device drivers. An unused 5.25" floppy drive card edge connector just hanging off the end of the floppy drive cable, may be used as a cheap connector.
