The REAP tools by InterGlossa Ltd support reverse engineering services, especially for microcontrollers such as the Zilog
Z80 and Intel 8051. These tools can be used to translate assembler and PROM formats to maintainable C and high level
forms and can also produce both off-line and interactive documentation for assembler programs.
The tools make use of the XANDFArchitecture Neutral Distribution Format.
