Hardware

 * 2x DDR3 Brand unreadable
 * ? NAND
 * AXP209 power management
 * Realtek RTL8188EUS wifi on separate PCB
 * USB OTG HOST (only with the adapter)
 * FocalTech ft5x TouchScreen

The usb (OTG ?) port can act as USB HOST as long as you have the correct adapter. It's really easy to make one: it's just a matter of shorting together pins 4 and 5 on the mini-B plug. I made my own for the Zaurus C1000 many years ago and I'm using it on this tablet now. You cab read more on usb connectors on Wikipedia.

Booting ordinary linux
I'm a Slackware enthusiast so I put up an article on the Docs Slackware wiki where I documented what I did to get a custom linux image booting on this device. I've done my best to keep it as neutral as possible. Have a look at the [article].

I've also an image builder tarball [here]. It's using the fedora boootloader and kernel but ships with a slackware mini root image. The image is also built rather then modified. With a little work it's possible to use any other distribution's root image.
