This Neoware CA22, Neoware part number DD-L2-GE, was manufactured in February 2007. This is based on the BCOM WinNET P680 (V4) board which is also used in a number of other thin clients such as the Igel 4210LX.

CPU

For those to whom it matters here is some detail from Linux's /proc/cpuinfo

vendor_id:CentaurHauls
cpu family:6
model:10
model name:VIA Esther Processor 1000MHz
stepping:9

Power Supply

This was not included, so I had to improvise. Conveniently the power supply requirements are on the cover +12V DC/4.16A/50W. I just use an old external power supply for the time being and it seems to work well.

Expansion

board

Both the Flash memory and the RAM in the CA22 are easily replaceable.

Flash: The flash is a "DiskOnModule" that interfaces via a 44-pin IDE connector.

RAM: The RAM is a 200-pin DDR2 SODIMM. The 512MB SODIMM fitted to my model is a DDR2-533.

PCI: PCI 2.2 connection which is at a right angle to the slot in the back, I think this would take a proprietary connector to function. Have not had a reason to try this yet.

On Board ICs

List of IC's I have managed to identify so far:

VIA VT8237R Plus- According the the datasheet this chip can do it all; audio, SATA, EIDE, V-RAID, USB 2.0, and sound.
VIA VT6103- 10/100 Ethernet chip
Winbond
W83697HG
- LPC Interface, Floppy Drive, Parallel port, Serial Port, Infrared port, Flash ROM, Game Port and MIDI port interfaces. No idea if any of these are connected to anything.
VIA VT1632A- This is the DVI Interface converter.
VIA VT1612A- Audio Chip... which is odd being that the VT8237R+ is supposed to be audio as well. Who knows which one is actually connected.

Minor modifications

I have added rubber "sticky" feet to the bottom due to the stands being destroyed in shipping. They have come in very handy.
