The operating system of the SIMpad SL4 is Handheld PC 2000 with parts of platform
builder both based on Windows CE3.0. The platform builder is a development platform
for putting together a tailor-made operating system for the desired application. The
Platform Builder itself is only the framework, and provides neither application programs
nor a graphic user interface.
Also based on Windows CE3.0, the Handheld PC 2000 platform has a complete set of
APIs and connectivity options. For a detailed description of Handheld PC 2000 see 5.3

In accordance with the modular concept of the Platform Builder, the operating system
is adapted to the hardware in use, particularly to the processor type. Executable
software for the SIMpad SL4 must therefore be written for Windows CE3.0 for
Handheld PC and for the StrongARM SA-1100 processor family.
