Bosanova RBT-802: Hardware 


 


 

 



Bosanova RBT800

This Bosanova (now 10ZiG) thin client is a small and neat unit. The label on the bottom of the unit identifies it as an RBT802. It also carries a label on the side identifying it as an ION A603. This is a Mini PC manufactured by First International Computer Inc (FIC) in Taiwan. I guess it was rebadged by Bosanova who launched the RBT-800 series at the start of 2007.

If you Google for ION A603 you'll find stuff about various mini PCs that were based on the same board.

Power Supply

The unit requires a 12V supply and uses a conventional 5.5mm/2.5mm coax connector.

Disassembly

You remove the back panel and then the circuit board can be slid out of the housing.

The back panel has a top and bottom strip of metal fingers that make contact with the inside of the housing. There are also a couple of plastic lugs that locate into slots in the base of the housing. The first time I took the unit apart I peeled back the self-adhesive rubber strips on the bottom to reveal these slots but subsequently realised this wasn't necessary. If you start by pulling back on the top edge of the back panel to get it at a suitable angle the lugs come clear of the slots and the back panel can be removed. There should be no need to poke a screwdriver through the slots.

Expansion

RBT-802 Circuit Board As usual, clicking on the photo (right) will take you to a larger scale photos of the top and bottom of the circuit board.

It is fairly compact in size so there is little space to fit anything internally. However, when I opened it up I found that it was fitted with a tray that would take a 2.5" disk drive that could be connected in place of the flash memory. There is space for this tray as, due to the low power of CPU, there is no heat sink on the CPU or the accompanying support chip.

Flash: The Flash memory is replaceable. It's a DOM plugged into a standard 44-pin IDE connector. If you decide to go down the Compact Flash route there is the disk tray that makes an excellent mounting point for your adaptor.

RAM: Having slid the board out there is no immediate sign of any RAM. It turns out that it's a conventional 200-pin SODIMM plugged into a socket fitted on the bottom the board.

The fitted SODIMM is marked A+ND333-56. This is a 256MB DDR333 (PC2700) 200-pin SODIMM manufactured by Aplus Technology Inc.

Wireless: The data sheet does mention an option of "Internal Mini PCI b/g wireless adapter". However I can't find any trace of any expansion connector on the board.

Link J7: This link controls whether or not the system will auto-boot when power is applied.
