Zaurus - pdaXrom / pdaXrom Calculator with RPN ported
« on: June 25, 2004, 12:06:38 am »
695K for a calculator!!! I'm guessing you linked all the libraries in statically.

Calcoo looks like a nice simple RPM calc. What I really want is to have the HP48GX Emulator, x48 - and I do - lardman has compiled it for arm and it works great. Only problem is it doesn't fit on the screen  

If I ever get any spare time, I'm going to have a go at re-arranging the layout of x48 so that it fits nicely into 640x480.

Since they don't support SDIO, your only choice for wireless cards is CompactFlash
According to this post:

a company called Mobile Link Technology does have a SDIO wireless card that is compatible with the SL-Cxx0 series Zaurii.

General Discussion / Zaurus as general PDA

You make a lot of very valid points. It's a good thing I don't want a general PDA, but rather I want a linux box in my pocket   For this there is no equal to the C series Z.

dh: thx for the info. I went back to the Panache site and was amazed to discover they make all sorts of very nice pen/pencil/stylus combos - just what I wanted.

1 - Has anyone here tried Toshiba SD cards?  Are they to be trusted?
IMHO Toshiba are the only SD card manufacturer to bother with. They developed SD cards (together with Matsushita (Panasonic) and SanDisk). Toshiba manufacture Panasonic branded cards, including their high end brand "Hagiwara". All their SD cards are made in Japan.

The price of US$90 is excellent, so I figured I'd try to find out exactly what was for sale. The seller has their 512Mb SD Toshiba OEM card on this website: which doesn't really have much info. They also have the card on eBay at which states they will ship worldwide for US$15.

Unfortunately they don't give a product number, but they look visually idential (but without the Toshiba brandname) to the cards on the Toshiba product info site here [Note the 2Gb SD card - mmmmmmnn].

There is another online seller (very similar name) that is also selling 512Mb Toshiba OEM SD cards here They are a little more expensive at US$96, but they do have a product number SD-M512B1. A little more searching turns up Toshiba's product release web page on SD-M512BX here: Note that these cards were only announced a year ago, and are capable of 10Mbits/sec, whereas the SD-M512B1 is 2Mbit/sec according to Digi4All.

Going off on a tangent a bit, I'd like to point out that Hagiwara have been making 10Mbit/sec SD cards for quite a while. They have their standard 2Mb/sec "T-Series" cards here: and their 10Mbit/sec "M-Series" cards here: (Of course the zaurus can't use the card at 10Mbit/sec).

I have had a 256MB Hagiwara "M-Series" card for about 10 months and it has performed flawlessly - I want to get a 512MB one, but they are very expensive:

So, getting back to the card have on offer, it is my suspicion that their Toshiba OEM 512Mb SD cards are old stock that pre-dates the announcement of the SD-M512BX 10Mbit/sec cards, and that they are rated at 2Mbit/sec.

It would cost me about AU$150 to get hold of these or AU$300+ to get a Hagiwara 10Mbit/sec card or AU$200+ to get a no-name card. Hmmn, I think I'm gonna buy one...... thanks for the tip-off

PS: After a reasonable amount of listening to hearsay and conjecture, it's my opinion that you should only buy SD/CF cards that are made in Japan - the rest have a much higher failure incidence.

Nice work offroadgeek - there are quite a few nice features with the new board - the "My Assistant" is great, and being able to get a comprehensive listing of all the recent posts is gold. I miss the quick reply box at the end of each page though.

Can I request that you install some more skins - neither of the two current are particularly appealing for me.


Zaurus - pdaXrom / HOW TO: Brightness Buttons
« on: June 23, 2004, 10:36:00 pm »
Very nice job Zazz. There's a similar thread with code at, but fl is a little bit more user friendly.

The thread by jgraves seems to have gone walkabout, but the benefit of setting up the key mappings for FN-3 and FN-4 in xkeymouse is that it will work under any window manager.

Code: [Select]
# /etc/xkmc snippet
# keycode, modifier, action, action arg, extra parameters...
keycode=51, Mod2Mask, Exec, /usr/local/bin/fl -, NoFork, NoAutoRepeat
keycode=52, Mod2Mask, Exec, /usr/local/bin/fl +, NoFork, NoAutoRepeat

Will using the 4.5 V adapter longterm cause any damage?
The meager limit of my knowledge has been reached and I'm afraid I can't give you an answer to that. However, I personally would seek out a 5V adapter rather than use a 4.5V one for the long term - the extra dollars are worth the peace of mind IMHO.

Angstrom & OpenZaurus / wot no bash shell?
« on: June 21, 2004, 05:30:11 am »
sh (the bourne SHell) is proprietry, bash (The Bourne Again SHell) is free. bash has a heap of additional features over sh, but because a lot of commercial systems only have sh and not bash, sh is still considered the standard. If your shell scripts are never going to come into contact with any corporate big iron, you don\'t need to worry what the differences are. For all things linux, there is only bash - sh is just a symlink to bash. (Of course, there are dozens of other shells you may wish to expore, csh, ksh, zsh, ash to name a few)

Now I don\'t know what is going on in OZ with sh - try sh --version and see what you get.

It depends on which side of the fence you sit. If you\'re used to a single user environment (ie: PC/Mac), then your agument stands. If you\'re used to multi-user systems, then running a multi-user OS in single user mode as root is a heinous crime.

Even though I trust myself (despite the fact I once wiped out a 1000+ user /home with rm -rf ../*), I really hate doing normal user tasks as root, and there\'s quite a bit of software doesn\'t like running as root either. There\'s a long established, proper way to do things - making life easy by running as root is a cop out - but I guess these days, on a personal single user system, it doesn\'t really matter.

<rant>there was a time, pre-linux, that having root access was akin to being a god</rant>

Accessories / Car power supply for C760
« on: June 20, 2004, 11:54:19 pm »
There\'s an eBay seller \"peakcloudy\" that sells very nice quality stuff for the zaurus at excellent prices - I got a car charger and a couple of external battery packs and they all work great in my 760 (I also got a couple of external power supplies, but wouldn\'t recommend these as they are only rated at 500mA).

As for a standard \"plug in the wall\" power supply, I recommend getting the biggest amps rating you can find. I sourced a nice 2 amp unit from the local electronics store and it charges the 760 fully in a couple of hours.

Be aware that the Z (or any device in fact) will only draw the current that it needs. So, if you give it 2 amps, then when it needs it, it will use it. If it\'s battery is fully charged and it\'s just idling, then it might only be drawing a few hundred milliamps - but the extra current is there if needed. On the other hand, if you plug in a power supply that is only rated at 500mA, then your Z will definitely run out of power. From memory, the Japanese supplied PS is rated at 1A, so I wouldn\'t go any less than this.  In fact, the 500mA PS I mentioned above tend to cut out - which I\'m assuming is because the Z is trying to draw more than 500mA from them. A cheap and nastly power supply will let a device draw more current than it is rated for - and that leads to power supplies overheating, meltdowns and even fire.

Of course, you also need to make sure the output voltage is within +- 5% of 5V. As for the input voltage, it\'s best to get an \"auto switching\" world wide power supply that is rated from 100 - 260V input. This way, you know you\'ve got all bases covered, and don\'t have to worry about voltage fluctuations in the local grid. My mobile phone has a 230V charger, but the local grid is 240V and can peak upto 260V - the 230V charger get real hot real fast! I would guess the reason your original PS died is because of this (What\'s it rated at, and what\'s your local grid providing?)

Accessories / Perfect Stylus
« on: June 17, 2004, 01:58:03 am »
I got a Pentopia from conics I was amazed at how much difference a decent stylus tip made. The lip where the thin inner shaft slides into the outer shaft is quite sharp and can be a bit uncomforable after extended use. I gotta admit, the panache looks more comfortable in this regard.

The biggest problem for me is that all the stylii available have the same outside diameter - obviously, so they can fit into the zaurus. After an hour or so of frantic note taking, my hand gets extremely tired from gripping such a thin pen.

Does anyone know of a stylus that is the same thickness and length as a normal pen?

Faster processor, graphics chip, more memory, bigger screen, etc. are a given, as are features like integrated wifi and bluetooth - it\'s just a matter of time. The only extra thing I want on my z right now is a back-lit keyboard - it\'s a real hassle to use in the dark.

General Discussion / VI: what\'s the big deal?
« on: June 13, 2004, 09:08:54 pm »
This thread sounds like a troll, but I\'ll bite. I\'ve been using vi for about 15 years and now I can\'t live without it. Yes, it is initially hard to use (took me a couple of years to get proficient) and has all sorts of obscure editing modes and commands, but what you can do with it is simply amazing - from a programmer/sysadmin point of view.

Lets put it this way, if pico, joe and nano were family hatchback cars, then vim would be a formula one racing machine. Anyone can drive a hatchback, but few would be able to handle a F1 racecar.

My advise is use the right tool for the job. If all you\'ve got to do is edit the occasional config file, then use something simple. If you\'re spending 8+ hours a day in front of an editor and need some real power, vim is worth the steep learning curve.
