Neoware CA2: Hardware 


 


 

 



Neoware CA2 thin client

Specifications

For the Neoware thin clients there is a handy document from HP which you can use to identify exactly what you have. In my case the label on the side of the case just says CA2. The HP document tells me that this is an early E100 model with a P620 board type and the Model Type is BH. There is no XX-XX-XX style part number on the unit. From the serial number it was manufactured in May 2003.

Powering it up I find that it's running XP Embedded Verison 2002 service pack 2.

The basic specs are:

The case size is identical to the Eon and larger than a lot of thin clients.

Power SupplyCA2 power

Unlike the Eon the CA2 uses an external 12V power supply. The power connector is the same style as used on the Compaq Evo T20 and some Wyse models so there is the possibility of some confusion here as those models run off 5V!

Expansion

Both the Flash memory and the RAM in the CA2 are easily replaceable.

Flash: The flash is a "DiskOnModule" that interfaces via a 44-pin IDE connector. There is also an alternative DiskOnChip DIL socket. (These are at the top right of the picture).

RAM: The board has two sockets that take 168-pin PC100 DIMM RAM. In the photo you can see these at the left-hand side between the heat sink and the power supply.

ISA/PCI: The board carries what looks like a PCI slot into which a small riser board may be plugged. The riser board carries an ISA slot and a PCI slot and allows an expansion card to be fitted within the CA2.

I occasionally get emails from people who have found that their recently purchased CA2 does not have one and wonder if I know of a source - I don't. However, after a recent email (June 2012) I did look a little further. As far as I can see this riser card is identical to the one fitted in the Eon. The CA2's BCOM number is E100. If you Google "neoware eon e100 riser" (or similar) you'll get a number of hits for people who are advertising them. The odds are very much in favour of these being ancient history and stock levels have been zero for years - but you never know. Also don't be surprised if the price is (very) significantly more than you paid for the CA2 in the first place! You may be better off buying another complete CA2 or EON.
