The Norhtec MicroClient exists in a number of guises and it's not immediately obvious what you've got hold of. The MicroClients I have seen carry no labelling. There are some differences in the packaging which may help you decide which of the various models it might be. Each model also had a number of options - Serial ports, WLAN etc which may or may not be fitted.
The MicroClient series are packaged in a case that's 11.5cm x 11.5cm x 3.5cm. There are occasional differences on the front panel such as the relative positioning of the Compact Flash slot and the USB ports, and the presence (or absence) of an on/off switch.
The back view appears to be same across the range. Exactly what is fitted to it will depend on the options taken up when it was bought.
This my best guess based on the information I can find on the internet. Please feel free to email me with any corrections if you know better. The various data sheets I've found have been devoid of any dates and, unlike with many other products, there seems to be a dearth of press releases or catalogues to help sort out the timeline.
The original [http://www.norhtec.com/products/mcrn/details.html] MicroClient was launched in 2005.
This was followed up in 2006? by the [http://www.norhtec.com/products/mcjr/index.html] MicroClient Jr. It was based on a 200 MHz SiS 550 CPU (x586 CPU with MMX extensions). It had 128MB of RAM onboard and 3 x USB1.1 ports. It had a Compact Flash card slot and an internal IDE connector.
Looking at the front panel the Compact Flash slot is below the USB ports and there is an on/off switch.
This was followed up in 2007? by the [http://www.norhtec.com/products/mcjrsx/index.html] MicroClient Jr SX. This was based on a "System on a Chip", the Vortex86SX, that integrates a complete computer on a single CPU. (NB No floating point support). The CPU clock rate was 366MHz and there was 128MB of onboard RAM.
Looking at the front panel the Compact Flash card slot is above the USB ports and there is no on/off switch.
The MicroClient JrSX boots directly off CF (Compact Flash), LAN or USB devices. Optional RS232 ports are also available. There are options to add 2.5 IDE drives, WiFi, etc. Due to space limitations if internal IDE drives are installed, you cannot install WiFi or serial ports.
In 2008? the [http://www.norhtec.com/products/mcsr/] MicroClient Sr appeared. This was based on the a VIA ULV CPU clocked at 500Mhz coupled to the VIA CX700M. (VIA UniChrome graphics engine). Originally this shipped with 521MB of memory but subsequently there was an option for 1GB of RAM.
It was fitted with 3 x USB 2.0 ports and a Type I/II CF Slot
