Model No: J400, Product ID: WT941GXL, Part No: 902073-29, Manufactured January 2007.
I've included this here as it is branded as a Winterm. I assume who ever named this product had a sense of humour and picked the XL suffix as, in terms of size, it is definitely not 'thin'! The right-hand photo above contrasts it with a Neoware Capio. When you look inside (see photo below) you can see why. The steel case carries a standard VIA EPIA Mini-ITX motherboard, a separate large heatsink connected to it via a heat pipe, a power board to convert 12V to the voltages needed by the motherboard and, finally, a lot of fresh air.
BIOS/Drivers/Manual et al used to be downloadable from the Legacy Product section of the VIA website. It looks these days you'll have to search and see what you can find. A copy of the motherboard manual is here.
The basic specs are:
VIA C3 Nehemiah
256MB (1GB max)
integrated Trident Blade 3D
1600 x 1200 @ ?-bit colour
4 x USB1.1
2 (Kybd & Mouse)
Dimensions H x W x D (mm) 68 x 300 x 290
The embedded operating system is Windows XPe.
My one came without any operating system installed - the flash memory had been wiped clean. A copy of XPe can be downloaded from the Wyse website if you wish to reflash the unit with the standard software. (I haven't done this).
The VIA Nehamiah comes in a number of flavours (see Wikipedia). There are:
On my unit /proc/cpuinfo reports a family/model/stepping of 6/9/4. According to sandpile.org this signifies a C5XL core.
The unit requires a 12V supply. Mine came with the official Wyse unit (part CFI941GXL) which is rated at a beefy 5A. This particular power brick actually draws ~4W without the Winterm connected.
There is an internal board that converts the 12V input to the various supplies required by the motherboard. This would appear to be a proprietary Wyse board.
Everything you need to know is in the motherboard manual.
The flash is a DOM plugged into one of the two 40-pin IDE connectors.
The RAM is a conventional stick of 168-pin PC133 SDRAM. According the manual each DIMM socket (there are two) will take upto 512MB DIMMs giving a 1GB maximum (2x512MB).
One thing to note is that there are no spare power connectors other than a small two-pin connector that matches the one connected to the DOM.
Note: The keyway pin on the IDE connector is missing. In some thin clients this is present, at least on the first IDE interface, as it is used to directly power a DOM. In it's absence you have provide power to a DOM through a separate connector.
There is a small riser board carrying a PCI socket so that a small expansion board can be added - such as another ethernet interface or wireless LAN card. What with that and the available internal space there is considerable scope to turn this into a useful appliance of some kind.
