C700
From OESF
Copied from the zauruszone wiki!
The C700 is the VGA resolution swivel screen Zaurus only available in Japan, or as imported through www.dynamism.com which has an english localized version. Basically it is way beyond cool. But it is hard to find information on it. TEST Links to info Using Babelfish...
1. Rom images:
To reflash the kernel, you need to reset and power on while holding either OK key (one is below the space key, the other is next to the power on in back) in to get the "maintainence menu". Then select menu item 4 (I can't read japanese so I don't know what it or the other three say). Then select CF or SD (it also has USB?) depending on where update.sh and zImage.bin are (there are two more files, but I was afraid of losing my english localization), then there is a final screen with japanese and a Y or N button. Do the Y button to update the kernel.

Other Miscellany:
The Yen and Backslash keys (requires the function key) are reversed.
Function-Shift generates most control characters (e.g. Fun-Shf-R will do control-r). To get the grave accent, use shift minus (next to space, Function gives @), For braces, do function-shift ,/< for { and function shift .?> for }. The backspace and arrow keys will also generate other VT100 or PC ANSI escape sequences (delete? home? end? page up/down?) when used in combination with shift and function.
Even if a network link is up (e.g. ppp on ttyS0 - the serial port like for my LG 5350 Sprint PCS cell phone), Qpe won't recognize it unless you do
qcop QPE/Network "up()"
as user zaurus (sudo is not there by default, so you have to do pppd as zaurus or switch). The console will work, but NetFront (the browser) will say the network isn't up until/unless this command is issued.
The sound input has higher fidelity and supports sampling rates of 8khz, 44.1khz and 48 khz.
The stock kernel has a well known bug that prevents the serial port from setting custom or very high (non-vanilla unix standard) baud rates (in drivers/char/serial_pxa200.c at the -EADDRINUSE around line 2650 - the Arm is memory mapped so the if port==port always causes failure since both are set to zero). You can go 115200 or slower as long as it is a standard rate. You cannot do 28800.
There is an entry in the file /home/zaurus/Settings/qpe.conf controlling the AC "screensaver" (the clock that comes up). Interval_AC_Screen Saver should be made very large if you don't want it (I don't know if you can shut it off entirely).
The charging circuit is more sensitive to too much voltage - it will blink if a 6v radio shack car power cord is used.
The Socket / Spectrum 24 CF Wireless card acts wierd - there was some support in the kernel or modules but it won't configure right.
The DLink 660WCF worked, though I don't remember if I had to tweak anything in /etc/pcmcia.
The windows driver can switch between network and IO modes. I set mine to network and disabled the checking service and other stuff, so it now always comes up just like any USB network adapter. It uses Samba to display the local storage as well as the SD and CF cards if inserted, and you can do ssh or other things if you install them.
You can add aironet and some other drivers without reflashing the kernel, though you will need the source and do enough of a make to put the configuration (.config, include/linux, etc.) files together and making modules.
However you can add extra filesystems, drivers, etc. and make others modules if you do reflash, and you can fix the serial port problem noted above.
The hostap, spectrum24 (with snax patch for kismet, using the orinoco driver), and everything else I have on my 5500 works on my C700.
