Sharp Mebius PC-NJ70A Resource Page

A remarkable oddball already on the first sight this small laoptop (Netbook) features a color TFT touch screen as the touchpad. And it gets even more interesting under the hood since the touchpad is actually a complete Linux PC itself with ARM processor, RAM, Harddisk(Flash), network and USB. It even seems to have a sound card (Which is not used afaik). Originally just PC-NJ70a (Without Microsoft office) and PC-NJ80a (With office personal). Sometimes also written with a "B" or "W" added like PC-NJ70A-B where "B" stands for black and "W" stands for white. there are also the PC-NJ70B and PC-NJ-80B which are the same machines, just with Windows 7 starter instead of Windows Vista Home basic.

Additional Applications

Tweaks (Attempt to turn some stuff to english)

General Tips:

- You can turn the japanese Vista into the english one without re-installing by using Vistalizator, a free tool to change the Vista (Or Win7) OS language
- The Touchpanel Display actually has its own CPU and memory. It seems its a USB device. I suspect you could communicate with it using the SPA.dll, but i havent researched much further yet. Yet there was no SDK released.
- The PC-NJ80A is the same model it just comes with Micosoft office.
- Installing Windows XP or Windows 7 is quite easy as the supplied drivers work on both of these systems as well.
