The Axel AX3000 M75C pops up from eBay from time-to-time. It is a small and light unit in a slim metal case which has obviously been designed by an engineer - just two sheets of bent metal! The thin client is based on the ST Microelectronics Atlas chip. The data sheet describes this as "X86 Core PC Compatible System-on-Chip for Terminals". Although the unit I have was manufactured in October 2008, the Atlas Datasheet I found is dated July 2002. On the ST Microelectronics website you'll find the data sheet in the obsolete products section. The CPU's part number is STPCI2HEYCE which breaks down as:
ST Prefix ST Microelectronics PC Product Family PC Compatible I2 Product ID Atlas H Core speed 133MHz E Memory speed 100MHz Y Package 516 Overmoulded BGA C Temperature Range Commercial
The CPU has no heatsink and does get quite hot.
The basic specs are:
1024 x 768 24-bit colour
2 x USB1.1
Kybd & mouse
Dimensions H x W x D (mm) 30 x 270 x 216
The AX3000/M75C has an internal power supply. It requires a clover-leaf style mains connector.
Neither the Flash memory nor the RAM in the M75C can be changed. The circuit board carries two 64MB RAM chips so there would appear to be 128MB of onboard RAM. With the flash there is a socketed chip (I haven't removed the label) which is usually the 'BIOS' chip. Other than that there is a 4Mbit flash memory chip. I have no idea how the firmware and non-volatile storage is spread between these.
