The Fujitsu Siemens S200 is one of the larger thin clients around. It's neatly packaged and, although not as power hungry as the s400, does carry the same warning label about using it vertically with a stand.

A datasheet I found on the S200 is dated July 2004.

Specifications

The basic specs for the S200 are:

Processor
Type    Speed	Transmeta TM5800 800MHz
Memory
Flash    RAM	32MB CF 128MB (max 512MB?)
Video
Chip    Max resolution    Connector	SiS315? 32 bit colors, 1600 x 1200 / 85 Hz VGA
Ports
Network    USB    Serial    Parallel    PS/2	10/100 4 x USB2.0 1 1 Kybd & mouse
Power
Power    Plug    Off    Idle    Running	100-240V 50/60Hz IEC 2W 13W 16W
Dimensions
H x W x D (mm)	246 x 48 x 177

My S200 came with eLux NG as the operating system.

Power Supply

The S200 has an internal power supply and uses a standard IEC connector.

CPU

The S200 is fitted with a Transmeta Crusoe clocked at 800MHz.

Disassembly

This is fairly straight forward. First remove the two screws that hold on the front cover. The front cover can then be gently slid forward. I found it to be a snug fit and it needed a bit of gentle encouragement to move. Next remove the two screws on the rear that hold on the top cover. This can then be removed.

Motherboard

The motherboard is labelled as a TR5670 Rev 1.33. Click on the photograph to get a more detailed view of the circuit board.

Expansion

Flash: The board is fitted with an Compact Flash socket so increasing the size of the flash is easy. There is also a 40-pin IDE socket. I haven't yet experimented with that.

RAM: The board has a single SODIMM socket for DDR memory. Mine came fitted with a PC2700S 128MB part - MT4VDDT1664HG-335F3. A 256MB part worked. Currently I have no 512MB part to try. I believe the integrated northbridge of the TM5800 will only support up to 512MB of DDR RAM.

USB: There are two USB 2.0 sockets on the front and two on the rear.

PCI: There is a PCI socket. My S200 came with a riser card.

Note: The power supply in the S200 delivers only +5V. However the PCI bus standard does include -12V on pin B1 and +12V on pin A2. These voltages are absent on the S200. This may affect any PCI expansion card you fit. A prime example are PCI sound cards where the +12V supply line is often used to power the on-card audio amplifier. You may think there's a software problem as you have no sound, but in reality it's the final amplifier stage that isn't working.

There are a couple of ways out of this:

1. Some users have found that connecting the +5V line to the +12V line is all that's required. The on-board amplifier still works reasonably even though the power supply has been dropped to 5V.
2. You can fit one of the many small and cheap DC-DC step up converters to provide the requisite 12V.
