The most interesting part is probably the main board.
DragonBall MC68EZ328 microcontroller, 8 MB GM71VS65163CL DRAM and the 2 MB AM29LV160DB Flash.
How to use this for own projects?
- The easiest option is to write a program which is then run by normal application by the Palm operating system. It should be possible to use the whole screen with its touch screen for a custom GUI. The real device is then connected via RS232.
- It would be way more interesting to use one's own firmware for the DragonBall microcontroller. This is quite complicated, because the development tools are only available at the original construction office.
