The back panel of an Itona fitted with a PV3B-VXL motherboard
I believe this motherboard to be fitted to the TC35xx and TC36xx series. What I have is a TC3541 and a TC3641.
The basic specs are:
Model TC3641 TC3541 Processor Type
Via C3 Nehamiah
Via C3 Nehamiah
64MB (max 1GB)
1600 x 1200 16-bit colour
4 x USB1.1
Kybd & mouse
Dimensions W x H x D 26.5cm x 5cm x 24.5cm Manufactured May 2005 February 2005
[*] My TC3641 has a dead PSU. Readings were taken using an external PC Supply.
Both units run Windows CE.
Linux's cpuinfo tells us:
TC35xx TC36xx CPU family : 6 6 model : 7 9 model name : VIA Samuel 2 VIA Nehemiah Stepping : 3 8
The motherboard has P3VB-VXL printed on it. It is fitted with either an 800MHz or 1GHz VIA C3 processor. It uses a VIA VT8601T northbridge with integrated graphics and a VIA VT82C686B southbridge. It has 2 dimm slots for low density (32x8) PC-133 memory. Each slot can handle up to 512 MB. In additional to the usual ports the rear panel also has a game port. (Some information on this board used be found at http://jim.geek-republic.com/ [Link found to be dead in 2016 and removed]).

As it is based on a mini-ITX board both the Flash memory and the RAM in the Itona are easily replaceable.
Flash: The flash memory is a Disk-On-Module plugged into the red 40-pin IDE connector. Unlike a lot of similar thin clients where the DOM is powered through pin 20 on the interface this is not the case here. The pin is missing and the DOM is powered externally via a separate connection to the power supply. There is a second 40-pin IDE socket on the board.
RAM: The board is fitted with two 168-pin PC100/PC133 sockets. While checking things out I added a 128Mb PC133 memory module to the second socket to provide 192Mb in total. A 256MB PC133 DIMM also worked ok, but I had problems with a double-sided 512MB DIMM. http://jim.geek-republic.com/?p=64 reported that "...It has 2 dimm slots for low density (32x8) PC-133 memory. Each slot can handle up to 512 MB".
PCI: The board does have a PCI slot on it, but the case is not engineered in a way that would let you make use of it.
