System Specifications

• CPU: Toshiba TX3922 129MHz MIPS 1. Little Endian.
• RAM: 32MB
• ROM: Unknown size, has Windows CE and numerous applications burned in.
• Framebuffer: 640x480 12-bit colour. Unknown chipset.

I/O Peripherals:

• LCD Touch Screen & keypad
• 1x RS-232 serial port
• 1x IRDA serial port
• 1x PCMCIA socket

Operating System Support

Natively, they run Windows CE 2.11 H/PC PRO 3.0. There is some resources on the net to suggest NetBSD potentially runs, but I have not succeeded in this endeavour. I'm looking into the feasability of porting Linux onto these devices.

A look inside

I ended up pulling my unit apart tonight... finally got fed up of the wobbly power socket, so I thought I'd take a look. The power socket was fixed very easy... The solder connections were worn... in fact, I suspect a manufacturing fault. Not to worry though, a quick jab with a soldering iron soon fixed up what the ravages of time had slowly worn away.

Motherboard: Top surface

Pulling up the keyboard, you'll see the top surface of the motherboard... shown in this photo.
