Alternate SDK 1.0a
the author of this app says:
ASDK is an alternative to the main programming tool for the handheld, a Macintosh application.
ASDK includes an assembler, a resource compiler, a Pilot emulator and debugger, a disassembler, header files, API documentation and a handful of utilities to aid in the development of Pilot applications.
In the future, expect a C compiler and other languages to be added to the kit, as well as more enhancements to make Pilot software development easier.
