Pi slave board for model B is under built and test.
some pictures of the prototype PCB, routed for model B :

The mainboard bare PCB

The optional 20x4 LCD display module

In the same time, a real time 3D user interface’s library is under development ( early stage picture of 3 surfaces acting like console’s char displays on the raspberry pi :

small window at back: 80x20 chars, wide window : 80x20 chars, a 3D object at top, and finally a rotating cube composed of 4 faces (12x8 chars) : about 6500 openGL polygons drawn and update in 13ms

August 28 : first assembly tests:
The assembly is ok , and the first tests to the development GUI are all ok also.

Some pictures of the device follows..

the LCD module stacked onto for the I/O mainboard.The LCD module is used for debugging purposes when code for the mainboard needs to be tested

The back side of the mainboard. the PI is plugged there using the GPIO port connector.The mainboard powers the PI. the mainboard's internal regulator generates 5V @1amp max from a DC source in the range 7 to 35V

For now, the application used to develop and test programs on the mainboard is using the SDL layer ( but a 3D gui is under development ).The upper window is the mainboard's program editor. the middle 2 window are dumps of the the 'compiled' code of the program on the upper window. finally, 4 little windows on the bottom are dumps of the mainboard's RAM datas, wich include 4 blocs : _PROG, _BLOCA ,_BLOCB, and _PARAM.
