It's been a while since I contributed anything, but today for some reason I just visited the forum and saw the simpad community alive.

Wow. This is so nice! I gave my 128 Mb RAM simpad to Koen Koei, in the hope he would develop some stuff so that the platform would not end up dead.

I don't know if it helped, but I'm happy to see so many people doing so many great things with the simpad, even so many years after it has been discontinued.

Wish you all good luck!

Due to a lack of time with my Zaurus activities (I'm just starting to live normally now), I am selling a Sharp IRIS prototype. Basically, it is a SL5500G (german SL5500 ie with a QWERTZ keyboard) with a GSM module. The GSM module has been tested in France - it is working fine, without simlock.

The device itself is flashed with a demo OS that I didn't have time to remove. There's no apparent easy way to reflash it but JTAG, so I'm including a parallel port JTAG reflasher if you don't have any, along with a linux kernel sourcetree supporting the Iris, and the documentation I have - the hardware manual of the LinkUp L7200, upon which the Iris is based.

The Iris uses standard SL5500/c7xx batteries and a similar 5v charger, which has been replaced.

Could be fun to have for anyone wanting a treo-like zaurus, and with enough knowledge to do the reflashing. It was never mass produced and is quite "rare". It is *not* for end users. If you don't do JTAG, don't get it, unless you want to have a vintage item for your Zaurus souvenir shelf.

It's 200 eur + real shipping costs. More pictures (including internal pictures) can be sent if necessary. Paypal or bank wire only.

Thanks to the generous loan of a C750, I could start experimenting with software "enhancements".

After some research on the forums, I found there were many discussion about video playback on the C7/8x0, with most people using 320x240 only. Well, looks like you can do much better than that ! Maslovsky and kfetisov reported vga playback at 248 kbps with mono audio, but that too can be improved.

After some tests, I could succesfully achieve 640x352@25 fps, with 500 kbps and stereo 64 kbps audio. You simply have to overclock with CCCR=163 (edit /home/zaurus/Settings/freqchange.conf to add a line above the "Overclocked"/162 entry with "Max overclocking" and 163)

Here's the script I used for encoding, along with the command line for playback. I recommand mplayer-w100_1.0pre5.2-1_arm.ipk.

I put the files on a 1GB CF, so the space constraint is not existant. I will now try to reproduce that on a 2.6 kernel, which I patched to add overclocking support.

Just a quick email to let you know I had a car accident in october, and I'm in the hospital until dec/jan with many broken bones. I've had a real net access since last week, and I first tried to sort of everything before passing the information.

As a consequence, development of the ROM has been fully halted. It also damaged the Acer N30 project I was working on.

Sorry about that. I will try to come back on the handheld linux world as soon as possible.

Regarding NAND upgrades, here is a pic of what I found in a Garmin GPS memory stick...
I am eager to try soldering a replacement. uboot from sashz could help, in the case the default bootloader don't recognise that chip.
