    Hi all!
    I like your forums here.
    I am a bit new to the whole tablet computer side, although i have been wanting one for several years now, i finally broke down and bid on one on ebay. I won this Itronix Go Book Duo Touch tablet pc. and me being the type of person that likes to take stuff apart and modify it. i was eager to take a screwdriver to it and see what is inside.
    My normal forums ( ) that i hang out at is more for audio and computer recording and i doubt that the folks over there would appreciate the information so i am posting the information here.
    I do hope someone finds the information useful.

    here is a link to my page detaining the disassembly of the PC.

    very interesting... whats the performance like, and what kind of OS is on it? It looks like windows because of the program title... It might be a not too shabby UMPC.

    hey, thanks for responding,

    the Itronix duo touch uses the Intel® Pentium® M 733 Ultra Low Voltage at 1.1 GHz Processor. there is 1280 MB of ram (256 MB of internal memory soldered on to the MOBO)

    here is what the detailed specifications say:
    512MB (PC2700) DDR SDRAM Standard (DDR333)
    Upgradeable up to a Maximum 1280MB (with one 1024MB SODIMM)

    with a memory slot nestled above the soldered in memory. this particular PC has a 1024 MB DDR card installed. the specs say that this is the most amount of memory the pc can handle. but the chip set is the Mobile Intel® 915GM and intel says "the 915GM Express chipset supports up to 2 GB of DDR2"

    This PC has a 40 GB shock mounted Haitachi 5k400 hard drive and there is room to place a hard drive heater under it which ironically is the same size of another hard drive. I called the manufacturer and they dont know what the second connector is for under the HDD. they suggested i contact the the design team. (although i serously doubt that they will give me any information relating to that.

    The hard drive is partitioned so that there is a recovery partition.
    the installed operating system is Microsoft® Windows XP® Tablet PC® Edition 2005 and is not embedded.

    you can boot to the bios post screen just by pressing the enter key when it is booting up. another thing to note is that the bios detects any memory storage device that is attached to the PC and they can be configured to be bootable. if you have a multi card reader hooked up the the usb port, the bios shows the card reader as an option for boot sequence.

    these computers have shown up on ebay recently as factory reconditioned units selling for about 600 bucks.

    my general impression og the Go-book Duo touch after having it and working with it for over a week now is a bit of a "love-not so much like" relationship.

    I love the fact that you can switch between the touch screen and the digital wacom pen with a touch of the button. this makes using the digital ink easy and typing is easy by switching to the touch pad option.

    the computer is quite powerful. i loaded Adobe Production Suite CS2 with Premiere and Encore. the programs could be faster loading but i think that is a bottle neck in the Hard drive interface, maybe a faster hard drive would help.

    but when loaded, there seems to be no problem with working in photoshop on medium sized files (800x600). and premiere seems to zip along well without to much of an issue. until you unplug the computer. the the processor goes into super slow mode and the clock frequency drops to 600 mhz to conserve battery life. but on a side note, i found an application that lets you throttle the processor speed either dynamically or manually depending on the work that is needed for output.

    The screen size is quite small with an 800x600 8.4 inch vertical viewable area.
    but the specifications of the PC and the software state that a secondary display through the expansion port supports:

    "a maximum of QXGA (2048 x 1536) resolutions up to 100-Hz refresh rate, dependent upon external monitor capability, and resolution and color depth settings"

    I have to wonder if the monitor can be reconfigured to take advantage of this secondary display option.

    here are the published specifications of this PC.

    Hi sabianq,
    Thanks for sharing the info.
    I plan to get a IX325 for its advertised ruggedness and outdoor readability (DynaVue). However, I am not sure how sensitive is the passive touchscreen (don't care much for the digitizer).
    I would like to know if the IX325 is sensitive to the finger tip. I use touchscreen computers (a toughbook CF-18 and a Fujitsu Stylistic 3500) for outdoor animal behavior data recording. The problem I have is that some (passive) touchscreens are designed to use a fairly sharp pointer to register pressure on the screen (like the Stylistic 3500). Others use less pressure (like the CF-18). The problem is that if high pressure is required I must use a sharp stylus, and I may lose real time data (we time the actions as they occur) when the touch is not recorded. I prefer to record accidental touches rather than lose data.
    So, how sensitive is the IX325 to the finger tip (in passive mode)?
    Second, I understand that the IX325 uses DynaVue technology for sunlight readability (about 300 NIT). The CF-18 does not have such feature, and I have to crank up the brightness to max 450 NIT to see the screen (also in black/white for contrast). The Stylistic 3500 is the R version (outdoor visible, reflective screen). It looks good outside even in color, and has long battery life due to lack of backlight. Have you tested the outdoor visibility on the IX325? How is it in full sun?

    i have damaged my screen and i have had no luck in finding a direct replacement. :(
    (my son dropped a big rock on the face)

    so far a mod may be the only solution

    however my touch screen still works and the rgb screen still works
    the piece that broke was the glass in between the touch part and the rgb screen
    i am thinking that it maybe possible to replace the broken glass with a piece of polycarbonate the same thickness.
    if i do the modification, i will post it here

    I bought 3 pcs of itronix duo touch IX325 with broken touch screens, without hard disks and cables for them. They were very cheap - 20 usd each :) but without hdd cable they were useless.
    So i have searched some information about them and found that chipset used in this tablets have support for Serial ATA. But how to connect SATA drive to mainboard ?
    On the PCB there was interesting brown connector (near ATA connector), i checked it with multimeter and bingo :) - this is SATA connector.

    So today i constructed a SATA cable, connected SATA drive and everything is working OK. Tablet found new hard disk as ATA HDD and booted from him.

    Here is pinout:

    1 - GND
    2 - A+
    3 - A-
    4 - GND
    5 - B-
    6 - B+
    7 - GND
    8 - +3.3v
    9 - +3.3v
    10- +3.3v
    11- GND
    12- GND
    13- GND
    14- +5v
    15- +5v
    16- +5v
    17- GND
    18- NC
    19- GND
    20- NC

    And some pics ;)


    PS - sorry for my english ;)

    Greetings ! I saw your posting on the disassembly, well done ! I also have one of these fine tablets but am in need of a replacement display for it. Other than Itronix, do you know where I may be able to obtain a replacement display for the IX325 ? I'd sincerely appreciate any leads !
    Best regards, ComputerMedic
