Fujitsu Siemens A250: Hardware

The Fujitsu Siemens A250 is a small and neat unit that is similar in
style to the VXL Percio. There is no date of manufacture on the unit
but the BIOS carries a date of 2007 and the data sheet on Fujitsu's
site is dated January 2008.

The basic specs for the A250 are:

Processor
	Type	Geode LX800
	Speed	500MHz

Memory
	Flash
	RAM	256MB (max 1GB)
Video
	Chip	CS5536A
	Max resolution	1600 x 1200 32-bit colour

Ports
	Network		10/100/1000
	USB		3 x USB2.0
	Serial		1
	Parallel	0
	PS/2		Kybd & mouse

Power
	Supply	12V 1.6A (Label)
	Plug	Coax 5.5mm/2.1mm
	Off	0 W
	Running	~9W

Dimensions
	H x W x D (mm)	195 x 152 x 43


The operating system is eLux NG. (Support now migrated to
unicon-software). I actually bought this unit new for £10 plus postage
and it comes with unlicenced software - you can apparently run it 38
times before it goes on strike if you haven't entered a valid licence
number by then.

Power Supply

The A250 uses a small external power supply that provides a 12V 2A
supply. The plug is a standard 5.5mm/2.1mm coax plug.

Expansion

Flash: Like the VXL Percio the operating system is stored on a Compact
Flash card that is concealed behind a cover on the left-hand side, so
a change of operating system/flash memory size is just a matter of
what is inserted here.

RAM: The RAM is a standard 200-pin SODIMM. The one fitted carries a
label 256MB DDR 333 (aka PC-2700). In October 2016 Darek emailed me to
say that he'd successfully installed 1GB of RAM.

IDE Interface: Unusually for modern thin clients the on-board IDE
interface is a 40-pin one (CDROM/3.5" drive) rather than the more
usual 44-pin laptop style.

Links: mfd emailed me to point out that jumper J3 - located at the
corner of the board by the power switch - makes the system auto boot
following a power failure.
